Data storage apparatus

摘要

Apparatus (1301, 1601) for storing data and supplying stored data comprising a main housing (113) containing control circuitry for controlling signals to a plurality of disk drives (401, 1605). The main housing (113) has a plurality of mounting mechanisms (508A, 508B, 509A, 509B, 510A, 510B) each configured to support a unit of a first type. The apparatus further comprises a plurality of cables (412) each having a first connector (414) for connecting to a unit of the first type for providing signals from the control circuitry. The apparatus has a first unit (1310, 1611), of a first type, having a plurality of second connectors (404) each connected to a disk drive (401) and a fan (601, 602) providing a flow of air for cooling the disk drives and the control circuitry. The first unit (1310, 1611) is connected to a first one of the cables (412) and mounted in a first one of the mounting mechanisms such that the first unit is mounted to slide into the main housing (113). The apparatus (1301, 1601) also has a second unit (1302, 1602), of a second type, supported by a second one of the mounting mechanisms and mounted to slide into the main housing. The second unit (1302, 1602) is connected to a second one of the cables (412) and has a fan (601, 602) providing a flow of air for cooling the control circuitry. The second unit 1302, 1602) is removable from the main housing (113) and replaceable by a unit of the first type.
