Reality Check: The FCoE Forecast
This is part of an ongoing series of longer articles I will be posting every Sunday as part of an experiment in offering more in-depth content.
There has been a lot of discussion in the storage industry about Fibre Channel over Ethernet (FCoE), making it the toast of Storage Networking World, but this technology remains relatively unknown to end users. Like so many storage protocols before it, the $10,000 question is whether FCoE will take off like iSCSI or fizzle as a niche product like FCIP, DAFS, and so many others.
If it does succeed, another critical question is what this means for iSCSI, Fibre Channel, InfiniBand, and to a lesser extent AoE, expanded SAS, and other options for SAN storage. The enterprise data center is poised for a complete change in server connectivity, with 10 Gb Ethernet converged network adapters (CNAs) and new core switches carrying both network and storage traffic, and this holds promise, especially in virtualized environments. But CNAs do not equal FCoE, and iSCSI, conventional Fibre Channel, and other protocols are roaring ahead. What impact will FCoE really have?
