Abstract
A system and method for handling IO to drives in a RAID system is described. In one embodiment, the method includes providing a multiple disk system with a predefined strip size. IO request with a logical block address is received for execution on the multiple disk system. A cache line size from a plurality of cache line sizes is allocated, based on the available memory for allocation to cache line. A plurality of sub-IO requests with a sub-strip size is generated, where the sub-strip size is smaller than the strip size, based on the allocated cache line size. The generated sub-IO commands are executed on the multiple disk system.
