Product Overview
HMM-199-A
The DSS-l disk subsystem provides up to 75 Gbytes of data storage in a compact,
rack-mounted peripheral enclosure. The enclosure contains up to eight 3.5-in.
(8.9 cm) hard disk drives with two separate, common power supplies. Both the
drives and the power supplies may be replaced during normal system operation,
which provides a high degree of equipment resiliency.
The DSS-2 is functionally identical to the DSS-l. The only difference is that the
connectors for the disk drives have a high insertion-cycle rating to enable media
storage between accesses. Disk drive canisters also have high insertion-cycle
connector ratings and the drives are designated RD-318 (equivalent to the
DD-318). RD-318 drives are not interchangeable with DD-314 and DD-318
drives.
Because most information in this document applies equally to the DSS-l and
DSS-2 subsystems, they are hereafter referred to as DSS-IIDSS-2.
