ABSTRACT:
A switched architecture for dual, independent storage controllers overcomes latency and coherency problems by an inter-controller command interchange scheme. The switched architecture permits a read or write command to be presented to either storage controller to effect data transfer on the same or the other storage controller. Communication between the two storage controllers is effected through internal Infiniband switches.
