Abstract
A method and related computer program product for achieving high performance I/O write rates in a redundant array using a fully recoverable communication queue stored in NVRAM on a RAID controller comprising, receiving an I/O write request from an application, determining if the I/O request is an inline write command, writing inline write commands into a command queue stored in NVRAM, notifying the application generating the I/O request of command completion and requesting the operating system for further I/Os.
