RAID Array 3000 Controller

This chapter describes the major features and characteristics of the Compaq
StorageWorks RAID Array 3000 Controller (Controller) in the controller
shelf.

Controller Overview

The controller provides high performance, high-availability access to SCSI
disk array subsystems along a Wide-Ultra SCSI bus. With a modular hardware
design and an intuitive configuration utility, the controller is designed to meet
a wide range of storage needs.

The controller consists of a single 5.5 in (14.0 cm) x 8 in (20.3 cm). circuit
board mounted in a subassembly. The package consists of the controller board,
a 300-pin connector, mechanical insertion assists, and a front panel LED/reset
switch interface. All signals to the controller are routed through the backplane
connector.

Figure 2–1 shows a simplified block diagram of the controller and its
interfaces to the major components in the RAID Array 3000. The unit is
configured with two Wide-Ultra, differential, SCSI host channels capable of
transferring data to and from the host at rates up to 40 Mb/s. The host SCSI
IDs are configurable via the host parameters and can support 32 deep tagged
queuing. The controller is also configured with two Wide-Ultra, single-ended,
SCSI disk channels capable of transferring data to and from the disk drives at
rates up to 40 Mb/s. Each channel can support up to 12 drives.
