Abstract
Systems and methods (including hardware and software) are disclosed where all common RAID storage levels are implemented for multi-queue hardware by isolating RAID stripes to a single central processing unit (CPU) core affinity. Fixed CPU affinity is used for any piece of data that may be modified. Instead of blocking CPUs that must access or modify a piece of data, the request is efficiently moved to the CPU that owns that data. In this manner the system is completely asynchronous, efficient, and scalable.
