The IEEE 802.3ba standard, in June, defines specifications for both 40G bps and 100G bps connectivity. Networking vendors have been racing to introduce 100-Gigabit Ethernet, which some organizations with fast-growing performance requirements say they need. Cisco Systems and Juniper Networks said even before the standard's ratification that they were trialing 100G bps equipment, and Juniper has said it is already accepting orders for it.

Brocade will give more details on the module next month, Chief Technology Officer Dave Stevens said during a media tour of the data center at the company's new San Jose, California, headquarters.

The NetIron MLX 32, the top-end 32-port member of the MLX line, will be able to accommodate 32 100-Gigabit ports, Stevens said. It currently can be equipped with 256 10-Gigabit Ethernet ports or 1,536 Gigabit Ethernet ports, all operating at line speed, he said.

Brocade uses two of the MLX 32 switches at the core of its new data center in San Jose, which consolidates resources that used to be spread among three facilities around San Jose. The MLX switches allowed Brocade to eliminate the aggregation layer, or "top-of-rack" switches, in its data-center network, making more room for servers and reducing requirements for power and cooling, Stevens said.

A variety of other features of the new facility will allow the company to reduce data-center energy consumption by 37 percent, compared to what the three other facilities were using before, executives said during the tour.
