Here are a few things to consider:
The biggest concentration of connections, traffic, switches, cables, NICs and HBAs are at the server edge.
The standards for FCoE and CEE are solid for the first hop (Server connection to Switch).
Converged Network Adapters (CNAs) are available and replace the NICs and HBAs in your servers today.
FCoE Switches and Director blades are available today and replace your Ethernet FC infrastructure.
The biggest advantage to a converged network infrastructure is the reduction in the amount of network components, such as switches, switch ports, SFPs, cables, NICs and HBAs. So it makes sense to start deployment at the server edge where you will be able to reduce the most infrastructure. There is no need to replace your entire Ethernet or FC network to benefit from a converged network.
At a practical level, focusing on a single hop for the first step to a converged network keeps the project manageable and maintainable. Start with tier 2 and 3 applications environments to gain experience with this new technology before converging the networks for tier 1 applications. Two deployment scenarios are possible today:
Top of Rack (ToR) FCoE Switch will reduce cables, SFPs and connections to the servers when combined with a CNA.
An End of Row (EoR) FCoE Director Blade will reduce cables, SFPs and connections to the servers when combined with a CNA.
