Abstract: A cable routing system includes a longitudinally-expanding body positionable within an IT rack having a frame and two or more NEMA rails coupled to the frame. A pair of mounting brackets are positioned proximate each distal end of the longitudinal-expanding body and configured to directly engage the frame of the IT rack. A cable routing tray is longitudinally affixed to the longitudinally-expanding body and configured to rout cables longitudinally along at least a portion of the longitudinally-expanding body. One or more vertical radiused supports are configured to define a minimum vertical bend radius for cables routed through the cable routing tray.

Abstract: A data storage interface for coupling data between processors and a bank of disk. The interface includes a plurality of first directors coupled to the processors and a plurality of second directors coupled to the bank of disk drives. A cache memory is coupled between the plurality of first directors and the plurality of second directors. The interface includes a pair of independent power busses. At least one of the first or second directors is coupled to the pair of independent power busses. One portion of the disk drives in the bank is connected to only a first one of the pair of power buses and a different portion of the disk drives is connected to only the other one of the pair of power buses. A power circuit includes a pair of input terminals, each one being electrically connected to a corresponding one of the pair of independent power busses. The circuit includes an output terminal. A pair of switching transistor sections is provided.
