Abstract:
1. A computer-implemented method comprising: identifying a specific usage for a storage system; specifying a quality of service (“QOS”) for the storage system; translating the quality of service into at least one performance benchmark; comparing the at least one performance benchmark to at least one performance indicator for a front end LUN, wherein the front end LUN is constructed from a plurality of slices from a plurality of backend LUNs, wherein the at least one performance benchmark is a numerical range that varies based upon, at least in part, at least one of a type of backend device contributing slices to the front end LUN and performance requirements of the front end LUN; if the at least one performance indicator exceeds the at least one performance benchmark, reducing the failure domain of the front end LUN; and if the at least one performance indicator does not exceed the performance benchmark, increasing the failure domain of the front end LUN.
