IBM brings to the show, as mentioned, Real-Time compression with full HW assist and Tiering via EasyTier. What was not mentioned is the ability for V7000 to virtualize external storage arrays and use the existing data volumes in place on 3rd party arrays. Over 270+ array types supported. All externally virtualized storage inherits the same rich suite of software features, tools, and data services. This really does add some differentiation to the UCS offering.
