I just read a lengthy article by Lucas Mearian in Computerworld online entitled “Protocol wars: Can Fibre Channel survive Ethernet's assault?” Of course the debate has been going on for years now so it is not new, but the article prompted me to want to provide my perspective on converged networks.
Let me start by saying that I am of the opinion stated in the article that long term Ethernet wins. However as the article correctly states Fibre Channel is still a growing market (albeit more slowly), and according to Gartner is in $50 Billion of equipment around the world.
IT managers are I am sure interested in the debate but are of course consumed by shorter term concerns than what connectivity they will use in 10 years time. Today’s reality is the total market is represented by a mix of Fibre Channel and Ethernet (principally iSCSI & NAS).
