System and method of I/O path virtualization between a raid controller and an environment service module in a storage area network |
摘要 |
A system and method of I/O path virtualization between a RAID controller and an environment service module (ESM) in a storage area network (SAN) is disclosed. In one embodiment, a type of I/O request is identified by an input/output (I/O) control engine upon receiving an I/O request from a host computer via a RAID controller. Further, a priority is assigned to the received I/O request based on the type of I/O request by the I/O control engine. Furthermore, the processing of the prioritized I/O request is interrupted by the I/O control engine. In addition, the prioritized I/O request is separated into a command I/O request or a status request. Also, the separated command I/O request or the status request is sent to an associated queue in a plurality of solid state drive (SSD) buffer queues (SBQ) in the I/O control engine.
