Abstract
A system and method for I/O optimization in a multi-queued environment are provided. In one embodiment, a host is provided that sorts commands into a plurality of queues, wherein a command is sorted based on its data characteristic. The host receives a read request from a storage module for commands in the plurality of queues and provides the storage module with the requested commands. In another embodiment, a storage module is provided that processes commands from a host based on the data characteristic of the queue that stored the command on the host. In another embodiment, a storage module sorts command completions into a plurality of queues, wherein a command completion is sorted based on its resulting status code.
