The IBM Storwize V5000 is a midrange block-storage system capable of virtualizing all attached disks and other attached storage systems. The V5000 is a storage system based on the IBM SAN Volume Controller virtualization software named IBM Spectrum Virtualize and is best viewed a less expensive version of the Storwize V7000 with a few differences in the features that are enabled. The V5000 is a multi-controller system with up to 504 devices in a cabinet along with the ability to virtualize external attached storage systems. A second cabinet of disks and controllers may be added in a clustering arrangement to scale even larger – up to 1,008 devices. The V5000 has three models that differ in hardware configuration and software features, allowing for different prices to expand the V5000 to a larger segment of customers.
Differences with the Storwize V7000 include the V5000 offers SAS host interfaces are supported, there is no unified offering, and a limit of scaling to two pairs of controllers in the largest model.
Competitive storage solutions for the V7000 and V5000 include the EMC VNX, HDS VSP midrange G- Series, and HP 3PAR 8000 while the virtualization solutions competition includes Hitachi Data Systems VSP G-Series, NetApp FAS8000 with FlexArray, and DataCore.
