Fibre Channel is to iSCSI what Beta is to BlueRay. The Fibre Channel guys are running scared. Customers see the tremendous savings offered by iSCSI, not only in acquisition, training, and operational costs, but savings from advanced virtualization technologies like thin provisioning, resource aggregation and high availability; It’s about doing more with less and solutions that allow storage to be managed independently of the hardware in the same manner as the new matriarch of storage--VMware.
Fibre Channel vendors have seen the writing on the wall and are now trying to save their ship by hopping on the Ethernet bandwagon. The technology is called FCoE (Fibre Channel over Ethernet.) Catchy name, huh? Which presumably will allow application severs to connect to Fibre Channel SANs over standard Ethernet, helping reduce the need for costly HBAs and switches. The hyped advantage is the elimination of TCP/IP overhead.
Will iSCSI kill FC?
