Following on from my previous post highlighting the EMC FCoE Tech Book, amongst the blizzard of nonsense press releases we see put out on FCoE sometimes the same one a few months apart, Stu put's his finger on the hot button issue around end to end FCoE deployment today.
Note that configurations of having FCoE traffic go through multiple FCoE (Ethernet) switches will require the updates which are being worked on in FC-BB-6 (although a small expansion of configurations specifically with blade servers should be able to be supported soon). FCoE today is a consolidation at the server and access layer – full end-to-end solutions with larger aggregation will take time.
Brass tacks is that routing FCoE traffic through intermediate switches is still a work in progress and a significant deployment limitation for end to end FCoE, that SAN topology you're used to having just not existing yet. Don't forget that when people crank up the hype train and try and sell you on tech which is still a work in progress. You can reap the benefits of FCoE in your existing FC environment today while keeping the deployment capabilities of your FC Fabric, but anyone promising you an end to end FCoE solution today is trying to sell you on taking a big step backwards.
