Force10 Networks plans 
to incorporate 40 Gigabit Ethernet (40 GbE) into its switch/router solutions for dynamic data centers. Initially, Force10 plans to incorporate 40 GbE into a 10 GbE top-of-rack access switch for converging Fibre Channel and Ethernet fabrics. The company’s E-Series core switch/router is already 40/100 GbE-ready, and its C-Series of resilient chassis-based switches are 40 GbE-ready.
Force10 anticipates that economic considerations will drive the deployment of 40 GbE in the data center. The company predicts that while future market factors will eventually reduce the cost of 100 GbE technology, the price point of 40 GbE will more cost effectively keep pace with the requirements for more bandwidth at the server edge, as well for higher capacity interconnects in the data center core.
Ratification of the 40 GbE standard by the IEEE is currently pending.
