Apparatus, system, and method for using multiple criteria to determine collocation granularity for a data source

摘要

An apparatus, system, and method are disclosed for collocating data. A mode module sets a collocation mode of a storage pool. The collocation mode specifies the granularity of the data to be collocated. In one embodiment, an assignment module assigns a source of data to a collocation group. A collocation module collocates the source's data to a minimum number of storage pool volumes based on the collocation mode of the storage pool and collocation group assignment of the source.
