1. A method for sharing non-volatile memory solid state drives across a cluster group, the method comprising: receiving, by a storage management computing device, a request for a block of storage in a non-volatile memory solid state drive in one of the plurality of non-volatile memory disk shelves; obtaining, by the storage management computing device, information associated with each of a plurality of solid state drives in the plurality of non-volatile memory disk shelves associated with the received request; creating, by the storage management computing device, a namespace for each of the plurality of solid state drives in the plurality of non-volatile memory disk shelves using the obtained information; and assigning, by the storage management computing device, the requested block of storage in the non-volatile memory solid state drive associated with one of the created namespace to a requesting client computing device.
