This chapter is an introduction to the StorageWorks product line and includes a general description of the products, components, and features. ------------------------------------------------------------ Note ------------------------------------------------------------ The configurations defined in this manual are for guidance only. They are current and correct as of the date of publication but are subject to change without notice. ------------------------------------------------------------ 1.1 How to Use this Guide Use this configuration guide as the starting point for developing a StorageWorks subsystem. This guide addresses the major considerations for designing a StorageWorks subsystem. Consider the following factors when designing your subsystem: · Host Computer System The host computer system to include the operating system and revision level; the SCSI (small computer system interface) controller or adapter used; the SCSI bus speed (fast or slow); and the SCSI connector type (high- or low-density, single-ended or differential, 50- or 68-pin). Each of these are discussed in the detail required for planning and configuring a system. Refer to the host or controller documentation for detailed information. · StorageWorks Subsystem Use A subsystem used for expansion storage does not require as much planning as as a RAID 5 (random array of independent disks level 5) subsystem. · Storage Devices When selecting a storage device you must consider the media type, storage capacity, reliability, and, when using multiple media types, the media must be compatible with the SCSI controller. · FCC Operating Environment All StorageWorks components can be used in a Class A environment. Some of the components can be used in a Class B (home) environment. All the components selected for a home environment must be certified as being FCC Class B compliant. Introducing the StorageWorks Family 1-1 This guide is organized into three major sections: ------------------------------------------------------------ For Information About See ------------------------------------------------------------ StorageWorks products including storage devices, controllers, shelves, and enclosures Part I--StorageWorks Products Digital systems that use StorageWorks subsystems Part II--Digital StorageWorks Compatible Systems Considerations for designing a StorageWorks SCSI bus to include cables and the general rules for configuring a StorageWorks subsystem Part III--StorageWorks Subsystem Planning ------------------------------------------------------------ 1.2 Product Features The StorageWorks subsystem shown in Figure 1-1 has the following features: · Low-cost SCSI device storage subsystems · Snap-in devices for instant installation and removal · The ability to mix 3½-inch and 5¼-inch storage devices · The freedom to design your own system · A redundant power option · Redundant cooling · Vertical or horizontal shelf orientation · Locking cabinets for security of high-dollar value, portable storage devices · Visual indication of shelf status, power supply status, storage device activity, and storage device status · Automatic reporting of shelf status to host · The capability to swap power supplies and storage devices without powering down the system 1-2 Introducing the StorageWorks Family Figure 1-1 StorageWorks Subsystem Components Introducing the StorageWorks Family 1-3 1.3 StorageWorks Building Blocks The StorageWorks building blocks (SBBs), shown in Figure 1-2, are the basic building blocks of the StorageWorks subsystem. They are available for both 3½- inch and 5¼-inch form factor devices. You can order SBBs with storage devices installed or you can install third-party devices in a StorageWorks modular carrier to create an SBB. SCSI bus converters, adapters, and power supplies can also be mounted in SBBs.

Check with your Digital account representative for availability of additional devices. ------------------------------------------------------------ Note ------------------------------------------------------------ No attempt has been made to define StorageWorks compatible third-party storage devices. Devices that meet the basic criteria defined in Table 2-1 may be installed in a modular carrier to create an SBB (StorageWorks building block). ------------------------------------------------------------ Table 2-1 lists the general specifications for all StorageWorks devices. Table 2-1 StorageWorks Devices--General Description ------------------------------------------------------------ Criteria Definition ------------------------------------------------------------ Interface The StorageWorks SCSI bus is SCSI-3 compliant. However, the shelves only support single-ended SCSI-2 devices. Device size (form factor) 3½-inch full-height or low-profile, fixed or removable media devices. 5¼-inch half-height or full-height, fixed or removable media devices. Power The total power requirements for the devices in one shelf cannot exceed 131 watts. To make sure this requirement is met, devices must spin up sequentially at 4-second intervals. Heat dissipation The SBB shelf blowers provide sufficient air flow to cool devices mounted in an SBB. SBB qualification All Digital devices have been tested in an approved StorageWorks configuration (that is, shelf, enclosure, power supply, cabling, sequential device spin-up at 4-second intervals, and so forth) and are in complete compliance with country- specific standards (for example, FCC, TUV, CSA, and so forth) and with Digital standards. Customers are responsible for testing third-party devices for compliance with country-specific standards. FCC certification All StorageWorks storage devices have been certified as being FCC Class A compliant. Some devices have been certified as being Class B compliant. FCC Class B installations require that all components, specifically the shelf, power supply, and storage devices, must all be Class B compliant. Use of a single Class A component in a subsystem requires that the subsystem be used only in a Class A environment. All SW500-series departmental servers and SW800-series data center cabinets can be used only in a Class A environment. ------------------------------------------------------------ StorageWorks Storage Devices 2-1 For information about a specific type device, see the following sections: Cartridge tape drives--Section 2.7 CD-ROMs--Section 2.8 Disk drives--Section 2.5 Magazine tape subsystems--Section 2.10 Solid-state disks--Section 2.9 Optical disk drives--Section 2.6 Information is presented in a tabular form and is organized by form factor, either 3½-inch or 5¼-inch, with their basic specifications (for example, capacity, media, transfer rate, rotational speed, and so forth). Detailed specifications are listed in the Digital Systems and Options Catalog. 2.1 StorageWorks Building Blocks The primary StorageWorks building block (SBB) is a SCSI-2 storage device mounted in either a 3½-inch or 5¼-inch carrier. The first step in designing a system is selecting storage devices with the following features: · Compatible media · Required storage capacity ------------------------------------------------------------ Note ------------------------------------------------------------ The SBB connectors are 96-pin female DIN connectors that provide positive mating with the SBB shelf male connectors. The connector design ensures that dc power is present until after the SCSI bus connection is broken and that dc power is applied before the SCSI bus connection is made. This feature protects the integrity of the SCSI data bus and avoids introducing noise on the bus that could either distort data or cause the bus to ``hang.'' The SBB connector is a simple, highly reliable mechanism that can support 200 SBB replacement cycles. Removing and replacing an SBB constitutes one replacement cycle. Over the projected StorageWorks active product life of 5 years, this equates to 40 replacement cycles per year, or approximately 1 cycle every 9 days. Excessive replacement cycles wear away the gold contact coating and thus destroys the integrity of the connection. The replacement cycle limit applies equally to shelf connectors and device connectors. Environments requiring a greater number of replacement cycles are not supported and are considered as improper treatment or use (paragraph 9.4b of U.S. Standard Terms and Conditions). Products or connectors damaged because of a higher number of replacement cycles are not eligible for return under warranty and standard service plans. Digital Equipment Corporation markets a distinct family of removable storage elements for higher replacement cycle environments.

The power supply type is determined by the internal enclosure power system, either ac or dc. Any shelf can have a redundant power supply to preclude a single power supply failure from disabling the shelf. In most cases, battery backup units (BBUs) can be combined with the shelf power supply to provide extended system data integrity. See Table 3-3 and the StorageWorks Solutions Shelf and SBB User 's Guide for more information about the power supplies. Table 3-3 contains the specifications for the BA35X-HA, the BA35X-HB, and the BA35X-HC StorageWorks power supplies.

The controllers, converters, and adapters are not interchangeable and can be user only with a specific type host. For general information about these devices, see the following sections in this chapter: Model ------------------------------------------------------------ Description ------------------------------------------------------------ See ------------------------------------------------------------ DWZZA-xx A SCSI bus converter for connecting a 16-bit differential SCSI host operating in the 8-bit mode to a StorageWorks shelf operating the single-ended, 8-bit, SCSI-2 mode. Section 4.5 HSD05(TM)-AA A storage array controller for connecting a DSSI (DIGITAL standard system interconnect) host to a StorageWorks shelf SCSI bus. Section 4.3 HSJ(TM)40-AD A CI(TM) (computer interface) compatible SCSI controller that supports up to 36 SCSI-2 disks, tapes, or optical devices. This controller includes a 16 MByte read cache and supports RAID 0 (random array of independent disks, level 0). Section 4.1 HSJ42-AD A CI (computer interface) compatible SCSI controller with two HSJ40-AD controllers. It is used for redundant systems. Section 4.1 HSD30(TM)-Ax A controller for connecting an 8-bit wide DSSI host computer to 3 SCSI-2 single-ended buses. Section 4.4 HSS9X-Ax The HSC controller seven device SCSI channel controller (K.scsi) for use with the HSC95 or HSR95 controller. This controller is part of the HSR95-series HSC rackmount servers. Section 4.7 HSZ(TM)10-Ax HSZ15-Ax A RAID array subsystem SCSI controller that can support up to 30 SCSI-2 devices on six SCSI buses or channels. These subsystems (SZ200-Ax series) are installed in deskside expansion units. Section 4.6 HSZ40-Ax A controller for connecting a wide (16-bit), differential SCSI bus to narrow (8-bit), single-ended SCSI bus. This controller requires using a DWZZA-series signal converter. Section 4.2 SWCDI-Ax The InfoServer controller is a dedicated SCSI storage server mounted in the upper half of a 5¼-inch SBB (StorageWorks building block). It quickly and efficiently transfers data between the StorageWorks SCSI devices and remote network client systems. Section 4.8 StorageWorks Controllers, Converters, and Adapters 4-1 4.1 HSJ-Series Controllers The HSJ controller series (the HSJ40 [6 SCSI ports] and HSJ30 [3 SCSI ports] controllers), shown in Figure 4-1, connect a CI bus to a SCSI bus. These controllers, their cache memories, and the power supplies are mounted in a BA350-MA controller shelf. The SBBs are mounted in SBB shelves. Both the controller and the SBB shelves can be installed in either an SW500-series or SW800-series cabinet. 1 There is no provision for installing these controllers in a deskside expansion unit. ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Installing CD-ROM devices and other storage devices on the same HSJ-series controller SCSI bus can cause time-out problems. Do not install any other storage device on a SCSI bus with a CD-ROM when using an HSJ-series controller. ------------------------------------------------------------ Figure 4-1 Typical HSJ-Series Controller Shelf Installation 4.3 HSD05 DSSI Storage Array Controller The HSD05 array controller, shown in Figure 4-2, connects a DSSI host to a StorageWorks SCSI bus. This 3½-inch SBB connects to the DSSI bus with a 50-pin micro-ribbon cable attached to the connector on the front. Switches on the back of the SBB define the DSSI node identification (node ID), the SCSI ID, and the DSSI bus termination. The DSSI trilink connector and DSSI terminator block provided with each HSD05 array controller are used to either position the controller in the mid-bus position, or to permit its removal without interrupting the bus. The HSD05 has two connectors: a 68-pin high-density DSSI connector to which the DSSI cable is attached, and a 96-pin DIN connector that connects to the SBB shelf backplane connector. The single-ended terminators are mounted internally and the converter can be used in either the end-bus or mid-bus position with an HSD trilink connector. Figure 4-2 HSD05 DSSI Storage Array Controller CXO-4052A-PH_RðTX 4.5 SCSI Bus Signal Converters The SBB shelf SCSI buses are 8-bit, single-ended, SCSI-2 buses. Some controllers and hosts, or their SCSI adapters, use a 16-bit, differential SCSI bus. Singled-ended and differential buses are incompatible and the SCSI protocol will disable both buses when they are connected together. As shown in Figure 4-3, SCSI bus signal converters permit connecting single- ended and differential buses together without modifying the SCSI devices. For an SBB shelf, the DWZZA-series SCSI bus signal converters are used perform the following: · Establish compatibility between the host SCSI bus and the SBB bus · Extend the length of the SCSI bus Two SCSI bus signal converters are used with StorageWorks products--the DWZZA-Ax and the DWZZA-VA. Electrically and operationally, these models are identical. The primary differences are as follow: · The DWZZA-Ax is a desktop model with a self-contained power supply that can be connected to an SBB shelf or a DWZZA-VA converter. The DWZZA-Ax has two female cable connectors--a 68-pin, high-density and a 50-pin, low-density. · The DWZZA-VA is always installed in slot 0 of an SBB shelf. It has a single female cable connector--a 68-pin, high-density. ------------------------------------------------------------ Note ------------------------------------------------------------ The DWZZA-VA input connector is a 68-pin, differential connector. There is no provision for connecting a 50-pin, single-ended connector to the DWZZA-VA. ------------------------------------------------------------ Both the DWZZA-Ax and DWZZA-VA models have internal differential SCSI and single-ended SCSI terminators. These converters can be installed in either the end-bus or the mid-bus position. The mid-bus position requires using the H885-Ax trilink connector block. The primary differences between the -Ax and the -VA convertors exist in the enclosures (the -VA is mounted in a 3½-inch SBB; the -Ax is mounted in a desktop enclosure) and the connectors. All of the cable connectors are high-density (HD). Table 4-1 describes the major differences between these converters.

The controller is only used with RAID array subsystems and is mounted in a controller and SBB shelf. This shelf has 5 SCSI buses, or channels, with one 3½-inch per bus (a one rank\ BOLD) 2 bus) that can be expanded by adding SBB shelves and 3½-inch SBBs up to a maximum of 30 SBBs (5 buses of 6 SBBs each, a 5x6 configuration). All the StorageWorks RAID Array Subsystem shelves are installed in deskside expansion units. The controller and SBB shelf is mounted in two deskside expansion units, as shown in Figure 4-4. The host SCSI channel is a synchronous/asynchronous, 10 MB/s (fast), 8-bit/16-bit differential channel, and supports the SCSI-2 protocol. The host connector is a 68-pin, high-density, female connector. The second connector is a SCSI output connector for connecting another controller or shelf in series. There are five 8-bit, single-ended, synchronous/asynchronous, SCSI-2 channels or interfaces. The controller provides active SCSI termination and terminator power. For additional details, see the StorageWorks RAID Array 110 Subsystem User 's Guide.

These controllers can operate with either a single-ended host or a differential host operating in the 8-bit mode and can be installed in either an HSC controller cabinet, such as the HSC95(TM) or in an HSR95-series data center cabinet. Figure 4-5 HSS9X-Ax ``K.scsi'' Controller Card ------------------------------------------------------------ CXO-4202A-PH ðTX 4.8 InfoServer Controller The InfoServer SW1000 controller SWDCI-AA, shown in Figure 4-6, is an inexpensive means of connecting a remote network client system to a StorageWorks SCSI bus. The SWDCI-AA is always installed in the upper half of a 5¼-inch SBB. The client system is connected to the SBB front panel connector with a thin-wire Ethernet cable. The SBB is always mounted in the the first three SBB shelf slots (slots 0, 1, and 2). The InfoServer SW1000 connector mates with the SBB shelf backplane connector in slot 0. The InfoServer SW1000 SBB device address switch is set to 7, the host controller address, thereby overriding the SBB backplane connector address. A half-height storage device, such as a CD-ROM, can be mounted in the lower portion of the SBB and its connector mates with SBB shelf backplane connector in slot 2. This device also has a SCSI device address switch. Figure 4-6 InfoServer Controller SWDCI-AA 5 ------------------------------------------------------------ StorageWorks Enclosures and Subsystems The following StorageWorks enclosures are described in this chapter: · SW800-series data center cabinets and subsystems (see Section 5.1) · SW500-series departmental servers and subsystems (see Section 5.2) · BA350-Kx-series deskside expansion units (see Section 5.3) · BA353-Ax-series desktop expansion units (see Section 5.4) StorageWorks shelves can be mounted in a variety of Digital enclosures.

A supported system has been evaluated in the specified configuration (that is, the host computer and SCSI adapter, and the StorageWorks controller, shelf, enclosure, SCSI cable, and supported StorageWorks building blocks (SBBs) and complies with country-specific standards (for example, FCC, TUV, and so forth) and Digital standards. ------------------------------------------------------------ Note ------------------------------------------------------------ The information in this chapter is general in nature and is for guidance only. See the Digital Systems and Options Catalog as well as Alpha AXP system, controller, shelf, and enclosure publications for detailed information about each element of the configuration.

Some systems have an embedded SCSI adapter in the host that can be used both for the internal and the external SCSI-2 buses. In many cases, the external SCSI bus requires another adapter, such as the KZMSA-AB, for the SBB SCSI bus. The rate at which the adapter can transmit data over the SCSI-2 bus, either fast (10 MB/s) or slow (5 MB/s), is independent of the other elements in the configuration. However, the devices on the bus, such as an RZ25-VA, may not be able to process data at a fast rate. The adapter identifies the maximum rate at which individual devices can process data and uses this rate for that device. ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ When the adapter can transmit at the fast rate and there is at least one fast device on the bus, the SCSI bus must be designed as a fast bus (maximum length 3.0 meters [9.8 feet]). This bus cannot function as a slow bus. ------------------------------------------------------------ StorageWorks-- SCSI Cable The SCSI cable recommended for connecting the host system to the controller, shelf, or enclosure. The cable length is a function of the physical configuration and the bus speed. SCSI cables are described in detail in Chapter 12. StorageWorks-- Component The information in this column defines the following:  The shelves used for the controllers or the SBBs  The enclosures containing the shelves StorageWorks-- Devices The devices that are supported in a specific configuration. Other devices may be compatible, but have not been evaluated in this configuration. ------------------------------------------------------------ Note ------------------------------------------------------------ Unless specifically stated otherwise, all buses are assumed to operate as a single-ended, slow SCSI bus with a transfer rate of 5 MB/s and a maximum cable length of 6.0 meters (19.7 feet). ------------------------------------------------------------ 7-2 Alpha AXP System StorageWorks Configurations Table 7-1 DEC 3000 AXP Deskside StorageWorks Configurations ------------------------------------------------------------ SCSI Adapter ------------------------------------------------------------ StorageWorks ------------------------------------------------------------ Models Model Speed Cable Component Devices ------------------------------------------------------------ 500 AXP 500S AXP Embedded Slow BC09D-06+  BA350-Kx deskside expansion unit (BA350-Sx SBB shelf) RRD42 RRD43 RRD44 RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B TLZ06 ------------------------------------------------------------  BA353-Ax desktop expansion unit RRD42-VE RRD43-VE RRD44-VE RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B SWXTE-VE TLZ06 TZ30-VE TZK11-VE ------------------------------------------------------------ 500 AXP 500S AXP 500X AXP PMAZ-AA PMAZ-AB Slow Fast BN21H  BA350-Kx deskside expansion unit (BA350-Sx SBB shelf) RRD42 RRD43 RRD44 RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B TLZ06 ------------------------------------------------------------  BA353-Ax desktop expansion unit RRD42-VE RRD43-VE RRD44-VE RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B SWXTE-VE TLZ06 TZ30-VE TZK11-VE ------------------------------------------------------------ + Minimum cable length. ------------------------------------------------------------ Alpha AXP System StorageWorks Configurations 7-3 Table 7-2 DEC 3000 AXP Desktop StorageWorks Configurations ------------------------------------------------------------ SCSI Adapter ------------------------------------------------------------ StorageWorks ------------------------------------------------------------ Models Model Speed Cable Component Devices ------------------------------------------------------------ 300 AXP 300L AXP Embedded PMAZ-AA PMAZ-AB Slow Slow Fast BN21H  BA353-Ax desktop expansion unit RRD42-VE RRD43-VE RRD44-VE RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B TLZ06 SWXTE-VE TZ30-VE TZK11-VE ------------------------------------------------------------ 400 AXP 400S AXP Embedded Slow BC09D-06+  BA350-Kx deskside expansion unit (BA350-Sx SBB shelf) RRD42 RRD43 RRD44 RZ25 RZ25L RZ26 RZ26L TLZ06 ------------------------------------------------------------  BA353-Ax desktop expansion unit RRD42-VE RRD43-VE RRD44-VE RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B TLZ06 SWXTE-VE TZ30-VE TZK11-VE ------------------------------------------------------------ 400 AXP 400S AXP PMAZ-AA PMAZ-AB Slow Fast BN21H  BA350-Kx deskside expansion unit (BA350-Sx SBB shelf) RRD42 RRD43 RRD44 RZ25 RZ25L RZ26 RZ26L RZ28 RZ28B TLZ06 ------------------------------------------------------------ + Minimum cable length.

Some systems have an embedded SCSI adapter in the host that can be used both for the internal and the external SCSI-2 buses. In many cases, the external SCSI bus requires another adapter, such as the KZMSA-AB, for the SBB SCSI bus. The rate at which the adapter can transmit data over the SCSI-2 bus, either fast (10 MB/s) or slow (5 MB/s), is independent of the other elements in the configuration. However, the devices on the bus, such as an RZ25-VA, may not be able to process data at a fast rate. The adapter identifies the maximum rate at which individual devices can process data and uses this rate for that device. ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ When the adapter can transmit at the fast rate and there is at least one fast device on the bus, the SCSI bus must be designed as a fast bus (maximum length 3.0 meters [9.8 feet]).

These rules may appear multiple times in this chapter because some rules apply to multiple products. There are two types of configurations rules--logical and physical. · Logical rules describe items such as selecting a device address. · Physical rules define capacities, cable lengths, and so forth. The following sections are organized by general subject and include both the logical and physical configuration rules. ------------------------------------------------------------ Note ------------------------------------------------------------ Configuration rules for a specific StorageWorks product have precedence over the general configuration rules listed in this chapter. ------------------------------------------------------------ General Configuration Rules 11-1 11.1 Device Addresses The following general configuration rules apply to StorageWorks device addresses: · Either the physical location of the storage device in the shelf or the device address switch setting determines the SCSI device address (small computer system interface) or ID of the following devices: - 3½-inch devices 1 - All 5¼-inch devices The physical location device addresses are assigned from right to left as viewed from the front, as shown in Figure 11-1. Figure 11-1 Typical SBB Shelf--Device Addresses CXO-3617B-PHðTX (7)ðTx POWERðTX 6ðTX 5ðTX 4ðTX 3ðTX 2ðTX 0ðTX 1ðTX ------------------------------------------------------------ SCSIðTx CONNECTORSðTX ------------------------------------------------------------ 11.2 SBB Shelves The following general configuration rules apply to SBB shelves: · Shelf capacity is measured by the number of 3½-inch SBBs in the shelf (refer to Figure 11-1). · Each 3½-inch SBB occupies one slot in a shelf. · All shelf power supplies and battery backup units (BBUs) are mounted in 3½-inch modular carriers. · Shelf power requirements are based on a maximum of seven 3½-inch SBBs. · All devices in a shelf must spin up sequentially under software control at a 4-second or greater intervals. · A 5¼-inch SBB requires three slots for mounting, as shown in Figure 11-2. Figure 11-2 Typical 5¼-Inch SBB Installation ------------------------------------------------------------ CXO-3608A-PHðTX 11.3 SCSI Bus The following general configuration rules apply to StorageWorks SCSI buses: · The maximum number of storage devices on a single SCSI-2 bus is seven. · The total length of an 8-bit, single-ended, SCSI bus is the distance between the two bus terminators. · The total length of an 8-bit, single-ended, SCSI bus operating at 10 MB/s cannot exceed 3.0 meters (9.8 feet). · The total length of an 8-bit, single-ended, SCSI bus operating at 5 MB/s cannot exceed 6.0 meters (19.7 feet). · The rate at which data is transferred over an 8-bit, single-ended, SCSI bus is primarily determined by the capabilities of the host SCSI adapter or controller. A controller is rated as either fast or slow based on the maximum rate at which it can transfer data. Prior to transferring the data, the controller determines the maximum rate at which each device can accept data. If this rate is lower than the controller 's maximum rate, the controller uses the lower rate for the transfer. This capability enables the reliable transfer of data to both slow and fast devices on the same bus, provided the bus is designed as a fast bus with a maximum bus length of 3.0 meters (9.8 feet). ------------------------------------------------------------ Note ------------------------------------------------------------ When the adapter can transmit at the fast rate and there is at least one fast device on the bus, the SCSI bus must be designed as a fast bus (maximum length 3.0 meters [9.8 feet]). ------------------------------------------------------------ · The total length of a fast-wide, 16-bit, differential SCSI bus cannot exceed 25 meters (82 feet). · Both a single-ended and a differential SCSI bus can be extended using SCSI signal converters. A maximum of two SCSI signal converters, including one installed in the shelf, such as a DWZZA-VA, can be used on any one bus. · A single, fast SCSI bus cannot be used for more than two shelves. · All SCSI buses require termination at both ends of the bus. · The single-ended SCSI buses are terminated on the last shelf on the bus. ------------------------------------------------------------ Note ------------------------------------------------------------ SCSI buses must be terminated at both ends for proper operation. SBBs do not terminate a bus; a BA35X-MB terminator board must be installed on the shelf backplane. ------------------------------------------------------------ · The rules for installing SCSI bus terminators and jumpers are shelf specific. · Multiple SCSI buses on a shelf can be connected together using a jumper board (BA35X-MC). For example, two buses can be connected into one; three buses can be connected into two, and so on. 11-4 General Configuration Rules · The target ID addresses for hosts and controllers are normally as follow: - First (single) host or controller: slot 7 - Second (dual) host or controller: slot 6 For a detailed description of the StorageWorks shelf SCSI buses, including lengths, see Chapter 12. 11.4 HSZ-Series Disk Array Controllers The basic rules for configuring the HSZ10-AA and HSZ15-AA disk array controllers (part of the StorageWorks Redundant Array of Independent Disks [RAID] subsystem) are primarily concerned with the disk drives. These rules, listed in Table 11-1, are dependent upon the RAID level (0, 1, 3, or 5). For detailed configuration rules, see the DEC RAID Subsystem User 's Guide. Table 11-1 StorageWorks Raid Array Subsystem 110 Configuration Rules ------------------------------------------------------------ RAID Level Drives per LU 1 Comments ------------------------------------------------------------ 0, 1, 3, 5 N/A All drives within a RAID level must be of the same vendor type and capacity. 0 1 to 5 None 1 2 to 4  Must specify an even number of drives  The mirrored pairs are created by grouping the first and second drive you enter as the first pair; the third and fourth drives as the second pair; and so forth  Mirrored pair drives cannot be on the same channel 3 3 or 5 None 5 3 to 5 Each drive must be on a separate channel ------------------------------------------------------------ 1 An LU (logical unit) is a grouping of drives that has its own device SCSI ID and number. For most purposes, a logical unit is equivalent to an array. ------------------------------------------------------------ 11.5 HSZ40 SCSI Disk Array Controller You must observe the following rules when configuring an HSZ40 SCSI disk array controller: · The HSZ40 supports only disk storage devices. · There is no provision for dual-redundant (two controller) HSZ40 configurations. · An HSZ40 SCSI controller supports the following host adapters: If Your System Is a ------------------------------------------------------------ The Controller Supported Is: ------------------------------------------------------------ DEC 3000 KZTSA Alpha AXP DEC 7000 KSMSA+ Alpha AXP DEC 10000 KSMSA+ ------------------------------------------------------------ +Requires a SCSI bus converter DWZZA. General Configuration Rules 11-5 11.6 HSJ Array Controller Family The hierarchical storage controller (HSC) CI configuration rules for supporting from 1 to 31 host nodes also apply to the HSJ array controller family. See the Software Product Descriptions (SPDs) and release notes for specific configuration rules for the following host adapters: If Your System Is a ------------------------------------------------------------ The Controller Supported Is: ------------------------------------------------------------ SBO-based system CI780 BI-based system CIBCA-B XMI-based system CIXCD ------------------------------------------------------------ CAUTION ------------------------------------------------------------ Installing CD-ROM devices and other storage devices on the same HSJ-series controller SCSI bus can cause time-out problems. Do not install any other storage device on a SCSI bus with a CD-ROM when using an HSJ-series controller. ------------------------------------------------------------ There are two types of HSJ array controllers--the HSJ40-series and the HSJ30-series. The HSJ40-series has six SCSI ports (buses) and the HSJ30-series has three SCSI ports (buses). The basic difference between these two types of controllers is the total number of devices supported. The HSJ40-series supports twice as many devices as does the the HSJ30-series. A single controller shelf, such as the BA350-MA, can contain two controllers and cache memories. Therefore, there are two sets of configuration rules: · Rules that apply to only the single controller configuration--see Section 11.6.1. · Rules that apply to both configurations--see Section 11.6.2. See the HS Family of Array Controllers User 's Guide for detailed information about the HS family of array controllers. 11.6.1 HSJ Single Controller The following general rules apply only to the single-controller configuration: · Install the controller either in the top slot or the right-hand slot. · A single controller port can support a maximum of two 5¼-inch, full-height (FH) SBBs in a single SBB shelf. · A single controller port can support a maximum of four 5¼-inch, FH SBBs in two adjacent SBB shelves. · A single controller port can support a maximum of six devices, using a combination of 3½-inch and 5¼-inch SBBs. · A single controller port can support a maximum of seven 3½-inch storage devices. 11-6 General Configuration Rules 11.6.2 HSJ Single and Dual-Redundant Controllers The following configuration rules apply to both the single- and dual-controller configurations: · The minimum number of power supplies per controller shelf and SBB shelf is one. · The preferred number of power supplies per controller shelf and SBB shelf is two. · The maximum number of SBBs supported by a single HJSJ40 controller is 42 (that is, seven devices per SCSI channel). · The preferred number of devices supported by a single HSJ40 controller is 36 (that is, six devices per SCSI channel). · The maximum number of SBBs supported by a single HJSJ30 controller is 21 (that is, seven devices per SCSI channel). · The preferred number of devices supported by a single HSJ30 controller is 18 (that is, six devices per SCSI channel). · CD-ROMs must be on a dedicated bus. No other storage devices, such as disks or tapes, can be on the same bus. · A maximum of two adjacent SBB shelves 3 can be connected to a single controller port. · Half-rack or full-depth devices, such as the TZ867 tape drives, must have a dedicated controller port. No more than two devices can be connected to a single port. ------------------------------------------------------------ 3 The second shelf is mounted directly below the first shelf with no space between them. General Configuration Rules 11-7 11.7 HSC SCSI Controller This section describes the general rules for configuring the HSC SCSI controller, commonly referred to as a ``K.scsi controller.'' For detailed configuration rules, see the HSC Controller User 's Guide. 11.7.1 HSC Controller SBB Shelf--Single SCSI Bus The following configuration rules apply when there is only one SBB shelf SCSI bus and a maximum of seven SBBs: · Install the terminator board (BA35X-MB) in the backplane connector adjacent to slot 1. · Install the jumper board (BA35X-MC) connector adjacent to slot 5. · The SCSI bus is a slow bus with a maximum bus length of 6.0 meters (19.7 feet). · Place the HSC controller in the end bus position for differential SCSI bus operations with a maximum bus length of 25 meters (82 feet). · Install the DWZZA-VA SCSI signal converter in slot 0. · Disable the DWZZA-VA SCSI signal converter, single-ended terminator when a SCSI ``A'' cable is connected to the upper (JA1) shelf connector. · Disable the DWZZA-VA SCSI signal converter, differential terminators when using a trilink connector block (H885-AA). 11.7.2 HSC Controller SBB Shelf--Dual SCSI Buses The following configuration rules apply when using both SCSI-2 buses on a shelf: · Install the terminator board (BA35X-MB) in the backplane connector adjacent to slot 5. · Install the jumper board (BA35X-MC) in the backplane connector adjacent to slot 1 for safekeeping. This board has no function in this configuration and installing it here does not affect the SCSI bus operations. · The SCSI bus is a slow bus with a maximum bus length of 6.0 meters (19.7 feet). · Place the HSC controller in the end bus position for differential SCSI bus operations with a maximum bus length of 25 meters (82 feet). · Install the DWZZA-VA SCSI signal converter in slot 0 or slot 1. · Disable the slot 0, DWZZA-VA SCSI signal converter, single-ended terminator when a SCSI ``A'' cable is connected to the upper (JA1) shelf connector. · Disable the slot 1, DWZZA-VA SCSI signal converter, single-ended terminator when a SCSI ``A'' cable is connected to the lower (JB1) shelf connector. · Disable the DWZZA-VA SCSI signal converter, differential terminators when using a trilink connector block (H885-AA). · Only the HSC controller connected to the upper SCSI connector (JA1) can monitor the SHELF_OK signal. 11-8 General Configuration Rules 11.7.3 HSC Controller Multiple SBB Shelves Multiple SBB shelves can be used with an HSC controller, and they can be configured as either a single- or dual-bus shelf using the following rules: · The single-bus or dual-bus configuration rules apply to each individual single- or dual-bus shelf. · Use the following rules to configure the first shelf: - Connect the HSC controller to the upper connector (JA1). - Install the jumper board (BA35X-MC) in the backplane connector adjacent to slot 5. - Connect the lower connector (JB1), the output connector, to the upper connector (JA1), the input connector, of the second shelf. ------------------------------------------------------------ Note ------------------------------------------------------------ Installing a terminator board in the first shelf will terminate the bus.

This bus has eight device addresses (0 through 7) that identify devices on the bus. · Device address 7 is normally reserved for the host computer address. · The remaining seven addresses (0 through 6) are used for the individual storage device addresses. StorageWorks shelves use a SCSI bus that can transfer data either at a slow rate (5 MB/s [Megabytes per second]) or the fast rate (10 MB/s). The rate at which data is transferred is affected by many things. However, the two primary concerns are as follow: · The maximum rate at which the controller or initiator can transmit data · The maximum rate at which the target device can process data The rate at which data is transferred over an 8-bit, single-ended, SCSI bus is primarily determined by the capabilities of the host SCSI adapter or controller. A controller is rated as either fast or slow based on the maximum rate at which it can transfer data. Prior to transferring the data, the controller determines the maximum rate at which each device can accept data. If this rate is lower than the controller 's maximum rate, the controller uses the lower rate for the transfer. This capability enables the reliable transfer of data to both slow and fast devices on the same bus provided the bus is designed as a fast bus with a maximum bus length of 3.0 meters (9.8 feet). ------------------------------------------------------------ CAUTION ------------------------------------------------------------ When the adapter can transmit at the fast rate and there is at least one fast device on the bus, the SCSI bus must be designed as a fast bus (maximum length 3.0 meters [9.8 feet]). ------------------------------------------------------------ StorageWorks SCSI Buses 12-1 The maximum length of the fast and slow buses, including all cables and shelf buses, is shown in Table 12-1. All bus lengths are rounded off to the nearest tenth of a unit. Table 12-1 SCSI Bus Parameters ------------------------------------------------------------ Bus Type Transfer Rate Meters Feet ------------------------------------------------------------ 8-bit, single-ended 5 MB/s 6.0 19.7 8-bit, single-ended 10 MB/s 3.0 9.8 16-bit, differential 20 MB/s 25.0 82.0 ------------------------------------------------------------ 12.2 Terminating SCSI Buses The shelf end of the SCSI bus is terminated with a terminator board mounted on the shelf backplane. See the individual controller documentation for termination options. ------------------------------------------------------------ Note ------------------------------------------------------------ All StorageWorks SBB shelf SCSI buses are terminated on the shelf backplane. There is no SCSI bus termination on any SBB device. ------------------------------------------------------------ 12.3 Computing SCSI Bus Lengths Operation of an 8-bit, single-ended, SCSI bus is affected by the total bus length (that is, the total distance between the two bus terminators). Failure to accurately determine the total SCSI bus length can cause signal degradation to the point where the bus is non-operational. Practical experience, especially when dealing with a fast SCSI bus (10 MB/s transfer rate), has shown that the limitations stated in Section 12.1 are applicable for most bus operations. Use the procedures in the following sections to determine the SCSI bus lengths for either single or multiple SBB shelves. 12.3.1 Single StorageWorks Shelf SCSI Bus Lengths As shown in Figure 12-1, the SCSI bus for a single shelf is composed of the following segments: · Segment A--The distance from the controller terminator (T1) to the SCSI bus connector (BC). · Segment B--The length of the SCSI cable from the controller shelf to the SBB shelf (either 1 meter [3.3 feet] or 2 meters [6.5 feet]). · Segment C--For a single SBB shelf this is the distance from the SBB shelf input connector (IC) to the shelf SCSI terminator (T2). Use the information in Table 12-2 and the following formula to calculate the length of a SCSI bus: T o t a l B u s L e n gt h = A + B + C 12-2 StorageWorks SCSI Buses Figure 12-1 SCSI Bus Segments--Single SBB Shelf Table 12-2 Single SBB Shelf SCSI Bus Lengths ------------------------------------------------------------ Shelf Bus Input Slot 1 Slot 5 Meters Feet ------------------------------------------------------------ Single Shelf--Single Bus ------------------------------------------------------------ 1 1 JA1 Terminator Jumper 0.9 2.9 ------------------------------------------------------------ Single Shelf--Two Buses ------------------------------------------------------------ 1 1 JA1 Jumper + Terminator 0.4 1.4 1 2 JB1 Jumper + Terminator 0.6 2.0 ------------------------------------------------------------ + The jumper is placed here for safekeeping and has no effect on the SCSI bus. ------------------------------------------------------------ StorageWorks SCSI Buses 12-3 12.3.2 Multiple StorageWorks Shelves SCSI Bus Lengths As shown in Figure 12-2, the SCSI bus for multiple SBB shelves on a single SCSI bus is composed of the following segments: · Segment A--The distance from the controller terminator to the shelf backplane connector (port) and from there to the SCSI bus connector · Segment B--The length of the BN21H-series cable from the controller shelf to the SBB shelf (either 1 meter [3.3 feet] or 2 meters [6.5 feet]) · Segment C--The distance from the first or second SBB shelf input connector through the jumper (J) to the shelf output connector · Segment D--The length of the SCSI cable (0.5 meters or 1.6 feet) that connects the SBB shelves · Segment E--The distance from the last shelf input connector to the bus terminator on the same shelf. Use the information in Table 12-3 and the following formula to calculate the length of a SCSI bus: T o t a l B u s L e n gt h = A + B + C + D + E Table 12-3 Multiple SBB Shelves SCSI Bus Lengths ------------------------------------------------------------ Shelf Bus Input Slot 1 Slot 5 Meters Feet ------------------------------------------------------------ Two Adjacent Shelves--Single Bus ------------------------------------------------------------ 1 1 JA1 None + Jumper 0.9 + 2.9 + 2 1 JA1 Terminator Jumper 0.9 2.9 BN21H-0E Cable 0.5 ------------------------------------------------------------ 1.6 ------------------------------------------------------------ Total Bus Length 2.3 7.4 ------------------------------------------------------------ + Do not install a terminator here. + From input connector (JA1) to output connector (JB1) ------------------------------------------------------------ 12-4 StorageWorks SCSI Buses Figure 12-2 SCSI Bus Segments--Multiple SBB Shelf StorageWorks SCSI Buses 12-5 13 ------------------------------------------------------------ StorageWorks SCSI Cables The process for selecting SCSI cables is basically the same whether or not the host system is a Digital system. Part II lists the Digital systems StorageWorks configurations to include the compatible SCSI cables. All you have to do is determine the cable length. For a non-Digital system, you must refer to the host system and controller documentation and determine the following: · The SCSI adapter or controller type · The SCSI connector pin configuration (50-pin or 68-pin) · The connector configuration (straight, right-angle) and latching mechanism (thumb latches, thumb screws, bale locks, and so forth) · The controller bus speed (fast [10 MB/s] or slow [5 MB/s]). For all host systems you must then calculate the maximum SCSI bus cable length. This is the difference between the maximum SCSI bus length, which is determined by the bus speed, and the total of the following: · The SCSI bus length between the controller terminator and the controller cable connector · The SCSI bus length between the shelf input connector and either the shelf terminator or shelf output connector · The special cables · The cables connecting the SBB shelves It is recommended that you select the shortest cable possible to connect the host to the StorageWorks subsystem. StorageWorks SCSI Cables 13-1 13.1 SCSI Cable Connectors All BA350-SB SBB shelves have two SCSI, 50-pin, high-density, female connectors. Only cables, such as the BN21H-series, with a SCSI 50-pin, high-density, male, straight connector can be attached to the SBB shelves. The BN-series StorageWorks SCSI cables are built to SCSI-3 specifications and operate reliably as part of either a fast or slow bus. Controllers can have both 50-pin, high-density, female connectors and 68-pin, high density, female connectors. Only connectors with a 50-pin, high-density, male, straight connector or a 68-pin, high-density, right-angle connector can be attached to the StorageWorks controller shelves. The following sections contain a general description of the StorageWorks-compatible SCSI cables for use with the following components: · Shelves · Controllers · Host computers or adapters All of the StorageWorks BN-series SCSI cables conform to SCSI-3 standards. 13.2 StorageWorks Shelf SCSI Cables All the StorageWorks shelves and expansion units, such as the BA350-KB deskside expansion unit and the BA353-Ax desktop expansion unit, have SCSI ``A'' type 50-pin, high-density, female, straight connectors. Only cables with a 50-pin, high-density, male, straight connectors, such as found on the BN21H-series cables, can be used. The following sections contain detailed descriptions of the compatible SCSI cables, to include connectors, typical use, and lengths: · SCSI-2, 50-conductor, single-ended ``A'' cables--Section 13.4 · SCSI-3, 68-conductor, differential ``P'' cables--Section 13.5 · SCSI-2 and SCSI-3 special purpose cables, such as ``Y'' cables, trilink connectors, and terminator blocks--Section 13.6 13.3 Recommendations for StorageWorks Shelves Digital strongly recommends that the same length cables be used to connect all the SBB shelves to the controller shelves in a cabinet or deskside expansion unit. The following advantages can be realized: · The cables between shelves will not be under any strain. · All the SCSI-2 buses are the same length. · The possibility of unbalancing a bus by inadvertently exceeding the maximum bus length is avoided. 13-2 StorageWorks SCSI Cables 13.4 SCSI ``A'' Cables The SBB shelf SCSI bus is an 8-bit wide, single-ended bus with two 50-pin, high-density, female connectors (JA1 and JB1). The compatible cable for these connectors is a 50-conductor cable with a 50-pin, high-density, shielded male, straight connector with thumb latches (also known as squeeze-to-release latches). This combination of conductors and connectors is a SCSI ``A'' cable. The primary difference between the ``A'' cables is the connectors. The following sections describe the different types of SCSI ``A'' cables that are compatible with the SBB shelves. Table 13-1 lists the SCSI ``A'' cable specifications, to include connectors, length, and cable order numbers.

This chapter contains examples of the steps involved in configuring some of the more basic subsystems. To reduce the complexity of the process, the examples are limited to subsystems that use the following: · HSZ10-AA disk array controller · BA350-Ex controller and SBB (StorageWorks building block) shelf · BA350-Sx SBB shelf · BA350-Kx deskside expansion unit with an ac distribution unit · 120 Vac 60 Hz input power 15.1 Before You Begin Before designing a StorageWorks subsystem, you should do the following: 1. Determine the storage requirements, to include the media, the storage capacity, and so forth. 2. Determine the bus type and the device that will control the bus. 3. Select the SBBs, controllers, shelves, and enclosures listed in Part I that meet your requirements. 4. Familiarize yourself with the configuration rules in Chapter 11 for the preferred configuration. 5. Determine which SCSI (small computer system interface) cables, listed in Chapter 12, are compatible with the preferred configuration, taking into account the shelf bus length, bus speed (fast or slow), and cable length. 6. Study the configuration examples presented in the following sections. Designing a StorageWorks Subsystem 15-1 15.2 StorageWorks Controller and SBB Shelf An example of a single controller and SBB shelf with one HSZ10-AA disk array controller is shown in Figure 15-1. Figure 15-1 Typical StorageWorks Controller and SBB Shelf Assumptions: The following assumptions have been made about this configuration: · The user wants one HSZ10-AA disk array controller. · The HSZ10-AA disk array controller is operated from a KZESA adapter. · The user wants a battery backup unit (BBU) to maximize data integrity. · The user needs 4 GB of storage in a RAID 5 (Redundant Array of Independent Disks, level 5) configuration. · The user wants the SBB shelf in deskside expansion enclosures. · The configuration will be used in France. Storage Capacity: This configuration uses five disk drives. Four RZ26-VA disk drives are used to meet the user 's storage requirements, providing 4.20 GB of storage. Because RAID 5 configurations require n+1 disks, an additional (fifth) disk drive is used to meet RAID requirements. Enclosure: Two BA350-Kx deskside expansion enclosures. 15-2 Designing a StorageWorks Subsystem SCSI Connections: In this example, two levels of SCSI connections must be considered: · The first is the SCSI connection from the KZESA adapter to the HSZ10-AA disk array controller. · The second is the SCSI connection from the controller and SBB shelf to the SBBs. The SCSI connection from the KZESA adapter to the HSZ10-AA disk array controller is accomplished with a BN21K cable and a ``Y'' cable (described in Chapter 12). A 68-pin terminator is also needed for this arrangement. The controller and SBB shelf can accommodate up to six SCSI buses. Each disk drive has its own separate SCSI bus from the HSZ10-AA controller. This connection is made on the backplane. Power Cord: A BN19W-2E power cord is used. Parts Lists: The parts list for the controller and SBB configuration in this example is as follows: · One BA350-Ex controller and SBB shelf · Two BA350-Kx deskside expansion enclosures · One HSZ10-AA disk array controller · Five RZ26-VA disk drives · Two BA350-HA ac input power supplies · One BA350-HC BBU · One BN21K-03 SCSI cable · One BN21P-0B ``Y'' cable · One H879-AA 68-pin terminator · One BN19W-2E Central Europe 220 V ac power cord (France) Designing a StorageWorks Subsystem 15-3 15.3 Combination BA350-Ex and BA350-Sx StorageWorks Subsystem An example of a configuration that uses a controller and SBB shelf and a SBB shelf is shown in Figure 15-2. Figure 15-2 Typical Combination BA350-Ex and BA350-Sx StorageWorks Subsystem Assumptions: The following assumptions have been made about the configuration in this example: · The user wants one HSZ10-AA disk array controller. · The HSZ10-AA disk array controller is connected to a KZESA adapter. · The user wants a BBU for the RAID controller and redundant power for the disks. · The user needs 9 GB of storage. · The user wants the SBB shelf in deskside expansion enclosures. · The system will be used in France. Storage Capacity: The configuration in this example has a total of 10 RZ26-VA disk drives, 5 in each shelf. These disks provide a total storage capacity of 10.5 GB: 9.45 GB to satisfy the user 's storage requirements, plus an additional disk to satisfy the RAID 5 requirement of n+1 disks. Enclosure: Three BA350-Kx deskside expansion enclosures. 15-4 Designing a StorageWorks Subsystem SCSI Connections: In this example, two levels of SCSI connections must be considered: · The first is the SCSI connection from the KZESA adapter to the HSZ10-AA disk array controller. · The second is the SCSI connection from the controller and SBB shelf to the SBB shelf. The SCSI connection from the KZESA adapter to the HSZ10-AA disk array controller is accomplished with a BN21K cable and a ``Y'' cable (described in Chapter 12). A 68-pin terminator is also needed for this arrangement. The SCSI connections from the controller and SBB shelf to the SBB shelves are accomplished as follows: · The SBBs in the controller and SBB shelf are connected to the SCSI buses internally, on the shelf backplane. · The SBB shelf is connected to the controller and SBB shelf with a BN21H-02 SCSI cable. Power Cord: A BN19W-2E power cord is used. Only two power cords are needed since the controller and SBB shelf can be powered from one ac distribution unit. Parts Lists: The parts list for this combination subsystem is as follows: · One BA350-Ex controller and SBB shelf · One BA350-Sx SBB shelf · Three BA350-Kx deskside expansion enclosures · One HSZ10-AA disk array controller · Ten RZ26-VA disk drives · Five BA350-HA ac input power supplies · One BA350-HC BBU · One BN21K-03 SCSI cable (for the HSZ10-AA disk array controller) · One BN21P-0B ``Y'' cable · One H879-AA 68-pin terminator · One BN21H-02 SCSI cable for the BA350-Sx SBB shelf · Two BN19W-2E Central Europe 220 V ac power cords (France) Designing a StorageWorks Subsystem 15-5 A ------------------------------------------------------------ StorageWorks Product Specifications This appendix chapter describes the physical and environmental specifications for the StorageWorks products.
