Product Overview

Key Features

The key features of the storage systems are:

∙Dual wide SCSI bus, either single-ended or fast/wide differential

∙Two redundant fan modules (shipped standard)

∙Two redundant power modules (one shipped, one optional)

∙Up to eight 1-inch-high, or four 1.6-inch-high slots

∙Optimized for high availability

High Availability

The storage systems are optimized for high availability with the following features:

∙Dual SCSI bus

∙Hot pluggable, front-accessible modules

∙Redundant fan and power modules

∙Can mirror disks in the same storage system

∙Can be integrated with mirrored disks in an HP-UX environment with MC/LockManager and ServiceGuard

∙Can be integrated with diagnostic tools to allow remote monitoring and troubleshooting.

SCSI Buses

The storage system contains two separate wide SCSI buses. One bus is connected to the slots in bay A and the other bus is connected to the slots in bay B. Each bus can be used independently, or can be connected together via an external SCSI cable to form one common bus. In a common bus configuration, four 1-inch disk modules can be installed in each bay for a maximum of eight devices per bus, or two 1.6-inch disk modules or DDS tape modules can be installed in each bay for a maximum of four devices per bus.

Modular Design

Each storage system contains the following modular components: fans, power supplies, disk drives, and DDS tape drives. Each component is housed in a plastic module. Each storage system contains two slots for fan modules, two slots for power modules, and eight 1-inch-high slots for disk modules or DDS tape modules. Each module is easily removed by pulling out a locking lever, is installed or removed from the front of the storage system, and can be used in any of the three storage system enclosures.

Fibre Channel (FC) SCSI Multiplexer (MUX) Connection

Fibre channel host connection is available through a Fibre Channel (FC) SCSI Multiplexer (MUX). Configurations of the FC are detailed in the HP 9000 Enterprise Servers Configuration Guide. For
