Patent ID: 8549224

Claim:
A method for identifying a logical unit (LUN) of a set of LUNs of a first storage group of a data storage system as a candidate for migration to a second storage group of the data storage system, comprising: receiving, by an analyzer device, a set of data associated with activity of the LUN of the first storage group; comparing, by the analyzer device, a performance metric value of a performance metric of the set of data, associated with the LUN, to a performance metric threshold associated with the performance metric; and when the performance metric value corresponds to the performance metric threshold, categorizing, by the analyzer device, the LUN as a candidate for storage on the second storage group, the second storage group distinct from the first storage group and having a disk type different from that of the first storage group; wherein the method further comprises, in response to receiving the set of data associated with the activity of the LUN, averaging, by the analyzer device, at least a portion of the set of data over a time period to generate a performance metric value associated with each performance metric.
