Disclosed is a computer implemented system, method and computer readable media for facilitating intelligent input/output (I,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,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 is in communication with the silicon specific target device and the block storage operating system module for efficiently handling event exceptions.
