The IBM Storwize V7000 is a mid-tier block-storage system capable of virtualizing all attached disks and other attached storage systems. The V7000 is based on the IBM SAN Volume Controller virtualization appliance using the IBM Spectrum Virtualize software and with unified file and block storage by the addition of a pair of servers called file modules running GPFS – IBM Spectrum Scale. The V7000 is dual controllers with up to 504 disk drives 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.
The IBM Storwize V7000 includes the licensed option for real-time compression of primary data. Data is compressed as it is transferred from cache to the storage devices or to external storage systems. Use of processor cores and hardware accelerator assist with an add-in card allow the compression to be done inline.
Competitive storage solutions include the EMC VNX, HDS VSP G-series, and HP 3PAR 7000 while the virtualization solutions competition includes Hitachi Data Systems VSP G-series, NetApp FAS with FlexArray, FalconStor FSS, and DataCore.
