EMC sees Unity as the eventual replacement for its VNX arrays, and its name is fitting. The VNX line has evolved over the past several years and is now available in all-flash configurations, but at heart it’s an aging platform that combines two even older systems: EMC’s Clariion SAN (storage area network) technology and Celerra NAS controller.
Starting fresh with a new design, Unity will be faster than VNX and take up less space. That 75TB all-flash configuration will be two rack units high (1.75 inches, or 44.5mm) versus 7U for VNX, Burton said.
