FAN or File Area Network is the latest buzz word for file virtualization, coined by Brad O’Neill, senior analyst at The Taneja Group. (He has some big clients in this space.) In June 2006, O’Neill reported that a Taneja Group survey of global IT decision makers, found that 62% of respondents now identify “file management” as either “the top priority” or “one of their top priorities” requiring immediate attention in their data centers. Meanwhile, Tony Asaro, senior analyst at the Enterprise Strategy Group has just posted an interesting blog on the FAN market, or rather what he sees as the lack of one. So which is it? Where have all the FANs gone?
