Abstract
According to one aspect, the subject matter described herein includes a method for tier-based slice allocation and data relocation in a data storage array. The method is performed at a data storage array including physical data storage capacity being logically divided into one or more logical units (LUs) and each of the one or more LUs being further subdivided into one or more slices, where the data storage array includes a resource pool being divided into a plurality of resource groupings, where each resource grouping includes one or more resources of a common type. The method includes receiving a slice allocation request for allocating a slice from the data storage array, where the slice allocation request includes at least one constraint. In response to receiving the slice allocation request, a slice that honors the at least one constraint is allocated.
