Description
The StorEdge A3000 controller module (FIGURE 1-1) is a compact unit designed to
provide high-performance disk array management services. Constructed for
installation and integration into StorEdge A3500 systems, the controller module

the same SCSI-2 bus interface for drive trays in the expansion cabinet. There
are two SCSI controllers inside the controller module that use five independent
drive channels to manage data distribution and storage for up to 60 disk
drives.
The controllers perform system status and fault detection functions as well.
The controller module chassis houses several removable, portable canisters:
