FIGURE 1-1 to provide high-performance disk array management services. Constructed for installation and integration into Sun StorEdge A3500 systems, the controller module supports dual SCSI hosts on a 16-bit SCSI-2 bus. In addition, the unit provides 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.
