Abstract: An apparatus and associated methodology contemplating a data storage system having a group of processor-controlled intelligent storage elements (ISEs). Each ISE in the group individually includes storage resources and a network interface. The storage resources of all the ISEs in the group collectively define a field of storage (FoS).

Orchestration logic executed by one of the ISEs of the group (a recipient ISE), in response to the recipient ISE receiving a storage management operation request via the network interface, queries the recipient ISE's ISEFoS in order to optimally determine which ISE in the group to use in executing the storage management operation request.
