Patent ID: 7281063

Claim:
An apparatus comprising: input/output (I/O) controller circuit boards; a storage array circuit board having storage device connectors to couple storage devices to the storage array circuit board; and a signal routing circuit board having one or more voltage regulators and connectors to couple the storage array circuit board to the signal routing circuit board, connectors to couple (I/O) controller circuit boards to the signal routing circuit board, and one or more multiplexers to route data signals in a selective manner along one or more first data signal paths between a first (I/O) controller circult board and the storage array circuit board and alone one or more second data signal paths between a second (I/O) controller circuit board and the storage array circuit board, wherein the second data signal path(s) share a portion of one or more data signal paths of the first data signal path(s), wherein edge connectors of the signal routing board removably connect to both the (I/O) controller circuit boards and the storage array circuit board while the storage array circuit board remains connected to a housing of the apparatus, the signal routing board and (I/O) controller circuit boards being horizontally disposed with respect to the storage array circuit board being vertically disposed.
