One or more aspects of the present disclosure relate to dynamically selecting a storage array and corresponding input/output (IO) paths between a host and the storage array. In embodiments, a virtual storage volume (VSV) can be established for a host entity using one or more storage device portions from a plurality of storage arrays. In addition, IO servicing metric parameters can be dynamically measured. The servicing metric parameters can define metrics corresponding to the VSV's assigned ports on each of the storage arrays or network latency between the host and each of the plurality of storage arrays. Further, a primary storage array from the plurality of storage arrays can be selected based on the IO servicing metrics.
