10GBase-T server NICs coming to market - 01/19/07 07:37 PM
The first 10Gig PCI-Express cards for the new 10GBase-T Ethernet standard are out. You do not yet have anything to connect them to but you can get your card now for when you do.
Chelsio Communications said its two new server adapters feature a single dual-speed 10Gig port and the company's T3 hardware accelerator, which offloads the host server by shifting all the TCP/IP network protocol processing - up to and including iSCSI - onto the card. The iSCSI-capable S310e-BT and the more basic N310e-BT are priced at $1995 and $1295 respectively.
By comparison, the TN7588 from Tehuti Networks includes a hardware-assist chip that works with its host server's TCP/IP stack to partially offload the server. It is available in single and dual-port versions.
Neither company is shipping in volume yet. Instead they are delivering samples to OEMs like server builders and the like. Until now, 10Gig Ethernet has all been fibre-optic or CX4 short-range (15m) copper. 10GBase-T should run up to 56m over CAT-6 or 100m over CAT-7 copper twisted-pair cabling, and the industry hopes it will give 10Gig a big boost, just as the ability to run over copper twisted-pair kicked Gigabit Ethernet sales into high gear.
There still seems to be a problem with power consumption and because of that distance.
