Abstract
A bus switch providing versatile data path routing between a first group of busses associated with a disk array controller and a second group of busses associated with the individual disk drives within the disk array. The bus switch comprises a plurality of bus multiplexers, equal in number to the number of drive busses. Each bus multiplexer includes a plurality of inputs, each input being connected to a corresponding one of the controller busses. The multiplexers are responsive to select and enable signals to connect selected controller busses to selected drive busses. The bus switch additionally includes a plurality of bus multiplexers for directing data from the drive busses to the controller busses. A parity generator comprising an exclusive-OR circuit is integrated with the bus switch. The output of the parity generator is also provided to each of the multiplexers and can be directed thereby to any of the controller or drive busses.
