In a marketplace marked by declining sales, Network Appliance took the lead from EMC this past quarter in the NAS area, with 38% revenue share compared with EMC's 31%. EMC had previously led the market for several quarters. In the open SAN market, Hewlett-Packard nudged EMC out of the top spot, taking 30% revenue share, compared with EMC's 27%.
Overall, EMC's worldwide disk sales fell 21% quarter-to-quarter, according to the report. Hitachi and IBM saw significant overall disk storage growth this past quarter, up 23% and 7%, respectively.
EMC did hold on to its lead in overall network storage market sales (NAS combined with open SAN), with 28% revenue share, according to IDC. HP maintained its market share lead in terms of total storage revenue, with 27% market share, followed by IBM with 20%.
Worldwide disk storage systems factory revenue was down 3% this past quarter, to $4.7bn. The NAS market fell 10%, and the open SAN market dropped 6% overall.
"The declining revenue picture can sometimes be misleading," said John McCarthy, vice-president of storage research at IDC. "The trend towards networked storage continues, which means that suppliers have to look beyond revenue to see that capacity growth of networked storage exceeds the growth of direct-attached storage."
