Abstract
Embodiments are directed to a method of optimizing disk striping input/output (I/O) operations to an array of storage devices, by identifying an I/O request as a full stripe write request that stripes data across a plurality of storage devices of the array, converting the full stripe write request to a SCSI command block (CDB), and putting the SCSI command block in one of a stripe cache or a non-stripe cache that comprises a sorted linked list where each node of the linked list is a link to one of the plurality of storage devices.
