Dynamic bifurcated bus width raid storage system

Abstract

A dynamic bifurcated bus width RAID storage system includes storage devices coupled to a root port on a processor via a switch that provides a respective bifurcated bus to transfer data between each storage device and the root port. A bifurcated bus width modification subsystem monitors the storage devices during their provisioning of a RAID storage system, determines that a RAID data movement operation is required, and retrieves a bifurcated bus width for each respective bifurcated bus provided by the switch to transfer data between each storage device and the root port. The bifurcated bus width modification subsystem then identifies a first storage device to which data will be written as part of the RAID data movement operation and, prior to its performance, increases a first bifurcated bus width for a first bifurcated bus provided by the switch to transfer data between the first storage device and the root port.
