Neil, Although this article raises some interesting points, including the inadequacies of Class 3, the biggest thing going for Fibre Channel is the fact that the storage devices will be using FC. Until that changes, I think Fibre Channel has the clear edge. I read somewhere that there is talk about putting Ethernet onto drives, but I don't know how far along they are. We clearly need to watch for this type of encroachment by the Ethernet camp, though. There is a lot of money behind the Gigabit Ethernet effort. Craig

It's FC all the way per Brocade Solutioneer techweb.com <<Various industry perceptions persist that current technologies can act as alternatives to a Fibre Channel-based SAN. However, this is not true. Gigabit Ethernet does not have direct storage interfaces; nor can it guarantee in-order delivery of frames at a network protocol level, which SANs require. OC-12 asynchronous transfer mode (ATM) has no direct storage interfaces. It also has a higher overhead-5 bytes out of every 53-byte frame, vs. Fibre Channel's 36 bytes out of every 2,112 bytes of payload-that is not at all suited to the large file transfers required in a SAN. Current Ultra SCSI-2 environments do not have the performance or the fault resilience necessary to provide the functional characteristics of a SAN. >> Neil
