Abstract
A method selects an interface in a storage subsystem for processing storage operations, each interface associated with a corresponding processor. A management server has plural providers, each for executing storage operations on one of the processors via the corresponding interface. The method comprises: collecting information on status of each of the providers; based on the status of each provider, determining an operational characteristic of operation time as a function of a number of operational units for each provider; comparing the operational characteristics of the providers; for a given number of operational units in the storage operations to be processed, selecting from among the providers one provider which has the lowest operation time for the given number of operational units; and identifying the interface based on the selected provider to be used for executing the storage operations via the identified interface on the corresponding processor.
