I doubt it actually.
From everything I’ve seen, customers aren’t using the 2 or 4 gigabit they already have – so why the sudden rush to faster and faster fibrechannel?
Mostly it’s to keep fibrechannel having the appearance of relevance in a world of 10G Ethernet and Infiniband. While I personally view SCSI over FC as being a much more mature protocol, I guess there is always the possibility that other options will be adopted. (I’ve done enough iSCSI implementations to know the powerful draw of cheap crap.)
My supposition is that while the upgrade to 8Gig FC will happen, it will not be a rush. Much as the push to 4Gig from 2Gig happened – through attrition.
I’ve been consulting for a long time. I don’t know a single customer that went out and bought new switches, new HBA’s and new storage just for the 4Gig technology. They did it the way they all do it – when replacing hardware that was going to be upgraded anyway.
I forsee the same adoption curve with 8GBit. It will happen because it’s a logical progression.
I would start finding a graceful way to explain to customers why they aren’t seeing a performance improvement though. (Outside of coincidentally adopting SSD at the same time) If you’re not using all of your 4Gigabit (or even your 2Gigabit for that matter) you’re going to end up not using all of your 8Gigabit….
