I continue to be amazed by the level of interest I’m seeing in Fibre Channel over Ethernet (FCoE) and 10 Gb Converged Ethernet among storage people. As I noted after my Charlotte virtualization seminar, end users at the largest enterprises seem to think that FCoE is their future, not just one of several options.
But when will 10 Gb and FCoE arrive? Dave Raffo and I discussed the topic after Storage Decisions, and he just wrote an article on the topic, 10GigE still seeking killer app. Here are some points that came up in our discussion:
- Shipping and supported 10 Gb HBAs and CNAs are the key requirement, and it looks like the schedules of Microsoft, VMware, Sun, and Linus Torvalds will determine when the floodgates open
- iSCSI people are talking 10 Gb, too, and they might end up adopting it first with software initiators
- Interest in FCoE is focused at the largest enterprise shops, and I’m seeing a distinct line between “iSCSI shops” and “(future) FCoE shops” with very little overlap (as I previously noted, iSCSI and FCoE aren’t mortal enemies, and FCoE will rule in the largest environments)
- No one is talking about 8 Gb Fibre Channel – they have all decided that 10 Gb FCoE or iSCSI is the next step for block storage
- InfiniBand has its believers (and they are rabid fans!), but the users I talk to are, as a rule, heading toward FCoE rather than IB for their future connectivity
- There is a tiny bit of user interest in moving back to SAS-enabled DAS for virtual server environments
- Everyone I talk to is shocked there isn’t a 10 Gb iSCSI array on the market yet, and we all expect to see this before FCoE
- Although some vendors have announced FCoE products, they’re not here yet – and it will be another year still before we see production deployment
