In storage area networking, there are really only two vendors to pay attention to: Brocade and Cisco. Combined, these two vendors dominate the Fibre Channel SAN switch market with some 90% of market share by revenue, according to Dell'Oro Group. The rest of the SAN switch vendors just don't matter, although we'd keep an eye on HP, which is showing more market share (by revenue) of Fibre Channel over Ethernet switches and adapters than Brocade, according to HP, though those numbers come from sales of FlexFabric, which includes Fibre Channel over Ethernet.
