Abstract
Disclosed is a computer implemented system, method and computer readable media for facilitating intelligent input/output (I.sub.2 O) message communication between a host computer system and a silicon specific target device without implementing an input/output processor. The system is thus configured to make generic storage silicon appear as though it were an I.sub.2 O capable device, without implementing an I/O processor and associated hardware. The system includes a block storage operating system module (OSM) for receiving a request from an operating system of the host computer system and generating an intelligent input/output message request. Also included is a host-resident intermediate service module driver (e.g., a RAID driver) for translating the intelligent input/output message request into a silicon specific request that is compatible with the silicon specific target device. Further included is a queue for holding the silicon specific request until the silicon specific target device pulls the silicon specific request from the queue via a PCI interface transport. In this implementation, the system also includes an exception handling operating system module (EOSM) driver that…
