While as I discussed in “The Elephant, The Blind Men and Fusion IO” the jury may be out on Fusion IO as a company it’s indisputable that putting flash right on the server’s PCIe bus keeps latency to a minimum and therefore maximizes application performance. Till now the problem has been that PCIe flash is usually used to emulate wicked fast direct attached storage and that means you have to choose between speed and the flexibility that VMware’s vMotion provides. In addition to acting as DAS EMC’s new Project Lighting will also act as a cache to shared storage enabling vMotion.
