Abstract: A disk array subsystem for use in a data processing system. In one embodiment, the disk array subsystem comprises a generally rectangular chassis having a top wall, a bottom wall, a pair of side walls, an open front end and an open rear end. A fan pack is removably mounted over the open rear of the chassis to cool the contents thereof by drawing air into the chassis through the open front end and out of the chassis through the open rear end. Disposed within the chassis are three power supplies, a pair of controller boards, a backplane, and a set of twenty disk drive modules. A mounting structure comprising four first disk drive module guide plates and a pair of second disk drive module guides is fixedly mounted within the chassis for removably mounting the disk drive modules in the chassis through the open front end and for placing the disk drive modules in approximate alignment with the backplane for electrical connection therewith.

Abstract: The invention comprises a storage system that facilitates the adjustment and rearrangement of vertically-stacked components comprising two oppositely-faced panels and a plurality of carriers having opposing side walls and a rear wall to provide a cavity for holding a unit to be stored, the carriers being stacked between the oppositely-faced panels in vertical array and being positioned relative to the oppositely-faced panels such that the carriers may be slidably moved in a vertical direction relative to the panels but positioned against removal from between the panels through the combination of a protuberance and recess interlock between the panels and each carrier, said protuberance being retractable from the recess to allow entry and egress of each carrier from the panels.
