Abstract
A system and method for receiving and responding to issued commands in a storage enclosure is disclosed in which each storage enclosure processor of the storage enclosure is coupled to each expander of the storage enclosure. Each storage enclosure processor receives each interrupt and command issued by another expander of the storage enclosure. In the event of a failure of one of the storage enclosure processors, any interrupts or commands issued by the expander associated with the failed storage enclosure processor will be handled by the operational storage enclosure processor. In this configuration, the storage enclosure processor can also arbitrate or determine the storage enclosure processor that will handle each interrupt and any associated command.
