Methods, systems, and computer readable medium for allocating portions of physical storage in a storage array based on current or anticipated utilization of storage array resources

Abstract

Systems, methods, and computer readable medium for allocating physical storage in a disk array are disclosed. According to one aspect, the subject matter described herein includes a method for allocating portions of storage area of a storage array. The method includes receiving, from a requesting entity, a request for allocation of a portion of storage area of a storage array, the storage array comprising a plurality of storage entities and a plurality of data buses for transferring data to and from the plurality of storage entities, wherein the plurality of storage entities are organized into at least one logical unit, wherein each logical unit is subdivided into at least one slice. In response to receiving the request for allocation, at least one slice is selected for allocation for use by the requesting entity, based on anticipated system resource utilization during access to data to be stored in the storage array.
