Expensive hardware, with little gain sadly. It was a nice idea, however at its very core is a fairly large problem: converged network adaptors are problematic.
Unless you have lots of bandwidth in said adaptor (ie 56gig inifiband) you are going to get contention between network and disk IO.
I agree, not only that, but at least with Cisco gear FCoE was a real pain in the behind to manage and configure. So much duplication in configuration and settings across a lot of gear, and it never was as smooth as they made it out to be.
