The Virtual Matrix Architecture allows Symmetrix V-Max Engines to interconnect and share resources . This enables a Symmetrix V-Max system to scale to 1024 GB ( gigabytes ) of global memory , with twice as many front-end and back-end connections compared to the industry-leading Symmetrix DMX-4 systems . The ability to interconnect and share resources to easily and linearly scale out is a key customer requirement as virtual machines and applications are dynamically added and shifted .
