Introduction

The HSD05 array controller is the entry-level product of the StorageWorks HSD

family of bus controllers. Installed in a 3½-inch StorageWorks building block

(SBB), the HSD05 array controller is used to connect a Digital host DIGITAL

storage subsystem interconnect (DSSI) bus to up to seven Small Computer

System Interconnect (SCSI) drives.

This chapter presents a basic description of the HSD05 array controller’s

features, performance, and operating environment. The HSD05 array controller

is shown in Figure 1–1; Figure 1–2 presents a typical HSD05 installation,

showing the relationship among basic system components.

1.1 HSD05 Array Controller Description

Connecting to a single port on a host DSSI bus, the HSD05 array controller

provides connectivity for up to seven SCSI or SCSI–2 disk, tape, and solid-state

disk devices. Enclosed in a 3½-inch SBB, it is mounted in a BA350-type shelf

containing up to six drives. Two shelves may be connected together to support

the maximum seven SCSI devices.

A DSSI bus connects to the HSD05 through a connector on the front panel; SCSI

bus connection is made through the shelf backplane connector. The HSD05 is a

TMSCP™/MSCP™-compliant device that performs the translations required to

support devices conforming to SCSI or SCSI–2 protocols.

The HSD05 array controller is shipped with a DSSI trilink connector and a

DSSI terminator that ﬁts on the trilink connector. The trilink connector allows

the HSD05 array controller to be connected as either an endpoint or a middle

(daisy-chain) node on the DSSI bus. Conﬁgured as a bus endpoint, the DSSI

terminator is used to properly terminate bus signals.

One or more HSD05 array controllers may be connected on the DSSI bus

containing RF™xx/TF™xx drives, host nodes, or other DSSI-compliant nodes (up

to eight nodes maximum).

1.1.1 HSD05 Array Controller Features and Capabilities

The HSD05 array controller provides the following features:

• Warm-swapping of attached drives (with a quiesced SCSI bus)

• Support for both OpenVMS VAX and OpenVMS AXP™ systems

• Multihost support for up to three host DSSI nodes in a cluster environment

• User-selectable SCSI and DSSI node IDs

Introduction 1–1

Figure 1–1 HSD05 Array Controller

CXO-4052A-PH

• DUP support for modifying operating parameters, such as DSSI nodename

and device allocation classes

• Host-based striping

• Host-based volume shadowing (with some restrictions)

The HSD05 array controller also exhibits the following performance metrics:

• 500+ requests/second (aggregate)

• 1.7 MB/second sustained throughput (aggregate)

Each device served by the HSD05 array controller is independently addressable.

Attached disk, tape, and solid-state drives appear to the host as standard

DIGITAL storage architecture (DSA™) devices. Disk allocation class is user-

deﬁnable, with all attached disks sharing the class value. Tape allocation class is

independently user-deﬁnable in the same manner.

The HSD05 array controller identiﬁes itself on the CI™ bus as a device of type

RF72; its software revision is RFX B1. This identiﬁcation is in device name only,

and does not reﬂect actual device geometries.
