ABSTRACT:
A serial storage architecture (SSA) storage subsystem which includes an SSA initiator and a series of SSA targets which include disk drives housed in a storage pod and an intelligent backplane of the storage pod which houses the other SSA targets. The intelligent backplane includes a controller, a series of status registers, each indicating status of an operating parameter for the SSA target drives, and a series of control registers, each configured to transmit a respective command to selected ones of said SSA target drives. The controller polls each of the status registers and, based on the contents thereof, determines whether an event relating to the operating parameter has occurred. If so, the controller reports the event to the SSA initiator. The SSA initiator may also control the target drives using the control registers.
