Something strange happened last quarter: According to IDC, the total percent of storage revenue--internal and external--that went to DAS increased to 56% of the market, up from 55% the previous quarter. External networked storage decreased from 45% to 44% of the market. But neither IDC analysts nor external storage vendors are willing to concede a trend. "We haven't seen anything that signals a shift in our data," says Jay Krone, EMC's director of Clariion platform marketing. If anything, IDC's numbers say more about server sales than they do about storage, per se. "The server industry had a bang-up Q4 for server sales under $6,000," says Krone. Those extra servers, he hypothesizes, "might be enough to move the needle toward SCSI JBOD." Furthermore, sales of external storage were "particularly weak" at IBM, points out Brad Nisbet, program manager for IDC storage systems, further skewing the data. In EMC's own Fibre Channel (FC) array business, the trend is decidedly away from direct-attached arrays--more than 80% of all Clariions ship with a switch or into ... Access >>>
