Abstract (en)
[origin: WO2006036810A2] A system, method and computer program for allocating physical memory from a group of N memory devices to logical volumes. A group of N memory devices are partitioned into a plurality of bands, each of the group of N memory devices sharing a portion of each of the plurality of bands. A cluster map for each of the plurality of bands is generated. The cluster maps indicate the physical address for each of a plurality of clusters. Each of the plurality of clusters are distributed equally over two or more of the N memory devices to ensure a specified level of redundancy for each of the plurality of bands. Each of the N memory devices share an approximately equal number of clusters. Available bands are determined and are allocated to a logical volume.
