Abstract
A system and technique for allocating and balancing storage resources includes: a plurality of storage controllers each controlling one or more storage volumes, and a processor unit operable to execute a management application to: determine, for each controller, an input/output (I/O) latency value based on an I/O latency associated with each storage volume controlled by a respective controller; determine network bandwidth utilization and network latency values corresponding to each controller; responsive to a request to allocate a new storage volume, select a controller having a desired I/O latency value; determine whether the network bandwidth utilization and network latency values for the selected 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 controller are below respective thresholds, allocate the new storage volume to the selected controller.
