FCoE Takes Next Step to Standards Completion
So the big news is that the FCoE standard continues to move forward by adopting a common addressing structure:http://www.primenewswire.com/newsroom/news.html?d=136174As soon as the release hit the wire, battle lines are being drawn. On one side, you have the Fibre Channel advocates supporting the standard but hedging their bets on how quickly it will be adopted. On the other side, you have the IP advocates who ask “Why can’t we just go straight to iSCSI?”An interesting discussion is taking place here.The reality is probably somewhere in between. The fact of the matter is that customers have invested a lot of money and time into their Fiber Channel infrastructure and they are not about to rip it out anytime soon. FCoE gives them a migration path that gets them immediate benefits of convergence while preserving their investment in hardware, applications, and processes.No one is saying that iSCSI isn’t a good idea for convergence in the data center. For many who haven’t invested in Fibre Channel SANs like small and medium businesses, it’s an ideal solution.But asking a storage administrator who has been running Fibre Channel SANs for years to throw it all away and start deploying iSCSI SANs is not realistic. It will probably be simpler to upgrade the Ethernet infrastructure to support Fibre Channel through FCoE than it would be to deploy a new iSCSI SAN and assess its impact on performance, availability, and management.
