Abstract: An air flow distribution system for a plurality of fans includes an air collimator that is operable to pass a flow of air in a linear vertical direction, thereby creating an improved optimal flow direction for cooling device components. The air collimator includes air transfer diverters to redirect swirling air from a fan into a linear flow, thereby increasing the cross-sectional air flow distribution throughout the device being cooled. Self-activating, separately controlled plurality of louver systems automatically close upon failure of an associated one of a plurality of cooling fans to prevent air from recirculating back through the failed fan. Therefore, air continues to move in a linear direction across the device components such that the device components remain at a specified temperature.

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: A disk drive module adapted for use in a data processing system, the system including first and second disk drive module guide plates. The disk drive module comprises an elongated, generally rectangular frame. The top wall of the frame includes a fin slidably insertable into a groove formed on the second guide plate, and the bottom wall of the frame includes a T-bar slidably insertable into a channel formed on the first guide plate. The T-bar includes a detent which releasably engages a pawl formed in the channel for securing the T-bar within the channel. A 3.5 inch disk drive and a regulator card are mounted within the frame. The regulator card is mounted on the frame for movement in three directions using bifurcated squeezable snaps inserted through oversized holes formed in the regulator card. Each snap includes a tab which limits upward movement of the card.

The rear edge of the regulator card includes an edge connector which extends rearwardly beyond the frame a short distance. To ensure that the edge connector is properly guided into engagement with a corresponding electrical connector in the data processing system, the regulator card is mounted on the frame for movement in three directions.
