Wouldn't it be cheaper
to just switch to 10 Gb ethernet? It has less compatibility problems, has the same throughput and in case of switched fabric, the reliability is the same. It could even use cat6 copper for cabling.
Several storage vendors plan to dive into 8 Gbit/s Fibre Channel gear in 2008, but it looks like Brocade will be first in the pool. The company announced that 8 Gbit/s blades for its 48000 Director have already shipped to OEMs for evaluation and will be available early next year. Brocade revealed the move today at Storage …
10GbEthernet and FC8 are completely different technologies, addressing completely different needs in IT infrastructure.
10Gb IP switches are currently very expensive and really only make sense for high speed core IP networking. Driving storage blocks over IP is still a relatively new technology (Fibre-channel has 10+ years of knowledge/experience) and customers looking for reliable high-speed deterministic performance will look to FC8 rather than 10GbE for the foreseeable future.
I do believe that ultimately we may see FC over IP, just as we see iSCSI (encapsulated SCSI commands over TCP/IP) at 1GbE today.
