EMC's flash storage refresh is more bark than bite, argues Wikibon CTO David Floyer. General availability for EMC's XtremIO flash storage system isn't expected until the summer of 2014 (EMC offers "directed availability" for now), and its XtremSF server flash cards only support the caching/reading of data found on external storage - by comparison, cards from Fusion-io (FIO) and others also support data writes, allowing them to run databases and Web/cloud services. Floyer's takeaway: EMC is still trying to protect sales of its high-end Symmetrix VMAX systems. Update: Floyer responds by stating EMC's XtremSF server flash cards do indeed support full read/write capabilities - a Silicon Angle article discussing his views had indicated otherwise. He also predicts EMC's XtremIO systems "will probably become the leading flash-only array product in the marketplace."
