Are there certain SAN applications that are better suited to Fibre Channel instead of iSCSI?
Fibre Channel is better as the storage array interface, simply because that’s what’s available today. As for storage applications, I can only think of one application – high definition video – that really leverages the use of 4Gbps Fibre Channel for the host connection. So today, Fibre Channel may be a better solution for post-production editing of HD video. For almost all other storage applications, it’s now possible to build two thirds if the SAN with IP (iSCSI hosts + IP storage switches) and use Fibre Channel at the storage interface.
