EMC VPLEX

[1] VPLEX implements a distributed "virtualization" layer within and across geographically disparate Fibre Channel storage area networks and data centers.

[13] In 2013, a product marketed with the phrase software-defined storage called EMC ViPR was announced, which could use VPLEX for its data movement.

Each director runs a Linux kernel and a specialized storage virtualization environment called GeoSynchrony, that provides proprietary clustering capability.

VPLEX is based on standard EMC building block hardware architecture components such as those used in its Symmetrix product line.

On the front end, VPLEX presents an interface to a host which looks like a standard storage controller SCSI target.
