FCoE network convergence will start at the edge but move to the rack
This article is part of the Network Evolution issue of December 2011 Vol. 2, No. 6
In this first part of this face-off on FCoE network convergence, storage and networking expert Stuart Miniman says 10 GbE and data center bridging are making it possible to implement FCoE now. Most will start with FCoE in the edge but soon move into the rack. CIOs have a huge challenge in the face of explosive growth in data and applications: They must control not only the cost of IT infrastructure, but also deal with diminishing power and space availability. What does that mean for IT shops? It means the need to look at fundamental architectural changes, including converged networks and storage. Fibre Channel over Ethernet (FCoE) is finally ready to meet that challenge—first at the edge but very soon in the rack. The IT community has worked for decades to deliver a single network for all infrastructures, but specific application requirements have spawned the development and adoption of multiple networks, including Ethernet for general networking, Fibre Channel (FC) as the primary storage network and InfiniBand for low latency ...

Hotspot 2.0 and the IEEE 802.11u protocol could allow mobile device users to securely roam between Wi-Fi and cellular networks without stopping to authenticate.
Implementing FCoE network convergence is possible considering the move to 10 GbE and the emergence of data center bridging.
FCoE at the edge can be a step toward network convergence, but end-to-end FCoE needs a whole lot more engineering before it can be reliable.
Think VM mobility and follow-the-sun data centers work for high availability and disaster avoidance? Think again. Long-distance migration is still a problem.
