Abstract: In an analyzer device, a method for identifying a logical unit (LUN) of a data storage system as a candidate for migration to a second storage group is presented. The method includes receiving, by the analyzer device, a set of data associated with activity of the LUN of a 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.

Abstract: Described are techniques for executing an application on two or more processors. A first portion of one or more modules of the application is determined. A second portion of one or more modules of the application is determined. The first portion of modules is executed on each of the two or more processor. A first of said two or more processor is selected as an active processor. The second portion of modules is executed on the active processor and not on the other ones of said two or more processors.
