"Fabric Convergence with Lossless Ethernet and Fibre Channel over Ethernet (FCoE)"
By BLADE Network Technologies
Fibre Channel (FC) is currently the defacto block storage protocol standard for implementing Storage Area Networks (SANs) in enterprise data centers. In 2007 approximately 90% of storage devices in the data center were connected via Fibre Channel. SANs deliver the following well-understood value propositions:
- Storage consolidation
- Centralized storage management
- High performance
- High reliability
- Rapid reconfiguration
Despite its popularity in SANs, Fibre Channel has not been accepted as a volume networking or clustering fabric. This puts Ethernet at a significant volume and therefore cost advantage to FC. The recent introduction of 8Gb/s FC marks the 4th generation of this long standing incumbent SAN technology.
However the rate of development of the Fibre Channel road map has been slower than Ethernet which has led FC to suffer a performance disadvantage to Ethernet. 10Gigabit Ethernet has been available for several years and Ethernet will move up to 40Gb/s and then 100Gb/s over the next few years.
