Ethernet gets twisted

Mellanox Technologies and Teranetics have teamed up to produce what they say is the first RJ-45 twisted wire-based interconnect for 10 Gigabit Ethernet (10GBase-T) on motherboards.

The ConnectX ConnectX is a PCI Express 2.0 chip that can support standard 10GBase-T as well as Data Center Ethernet, Fibre Channel over Ethernet and InfiniBand over Ethernet. It uses the standard Ethernet Media Access Control (MAC) and physical device interface (PHY) architectures. Each controller will have two ports.

"From the data-center manager's perspective, they don't have to buy adapters to have high-performance use," said TA Ramanujam, senior product marketing manager at Mellanox.

“10GBase-T on the motherboard will allow server vendors to offer a significant connectivity performance upgrade that reduces some key bottlenecks in virtualized and high-demand computing environments,” said Nik Simpson, a senior analyst at the Burton Group, in a statement. “An integrated MAC/PHY solution makes it possible to offer this upgrade at a reasonable cost.”

Ramanujam expects motherboards with the new technology to hit the market by mid-2009.
