Abstract
A storage array engine has two single-board storage directors with CPU complexes and PCIe switches that are interconnected by a fabric-less PCIe NTB. IO response times of the storage directors are modeled, e.g., as a function of controller memory interface bandwidth utilization, switch utilization, fall-through time of a non-mirrored segment of the volatile memory, central processing unit complex utilization, number of available data slots in the non-mirrored segment of the volatile memory, and average depth of all IO-related queues. Responsive to receipt of an IO, a data slot in either local or remote storage director memory is allocated based on the difference between computed IO response times of the storage directors. The fabric-less link is used to service IOs using remote memory, thereby mitigating additional loading of the local CPU complex.
