EMC announced VPLEX at EMC world however, it was hinted at during Getstalt IT’s Tech Field Day at least in its asynchronous mode. What does VPLEX do? What does it mean to the virtualization and cloud industries? These were the discussion within the Blogger’s lounge at EMC World.
What does it do?
VPLEX maintains cache concurrency between two geographically separated storage arrays up to 100kms apart. Over that distance and VPLEX changes to an asynchronous mode. This asynchronous mode is not yet available even so, VPLEX offers a degree of disaster recovery unheard of today for non-virtualized loads, but for virtualization loads, it provides improved business continuity.
