ALLOCATION AND BALANCING OF STORAGE RESOURCES

摘要

A method and technique for allocation and balancing of storage resources includes: determining, for each of a plurality of storage controllers, an input/output (I/O) latency value based on an I/O latency associated with each storage volume controlled by a respective storage controller; determining network bandwidth utilization and network latency values corresponding to each storage controller; responsive to receiving a request to allocate a new storage volume, selecting a storage controller having a desired I/O latency value; determining whether the network bandwidth utilization and network latency values for the selected storage controller are below respective network bandwidth utilization and network latency value thresholds; and responsive to determining that the network bandwidth utilization and network latency values for the selected storage controller are below the respective thresholds, allocating the new storage volume to the selected storage controller.
