Super-speed Ethernet start-up wins IBM backing
Published: 31 Oct 2005 09:30 GMT
IBM plans to begin selling Ethernet adapters from Neterion on Monday, the most significant partner thus far for a start-up whose products transfer data at 10Gbps.
Big Blue will sell the products under its own name for use in its higher-end Intel-based servers such as the x460, said Neterion chief executive Dave Zabrowski. The product uses the company's second-generation Ethernet chip and plugs into a PCI-X 2.0 slot. IBM also will use the company's drivers to support the adapters.
"It's very significant," Zabrowski said of the deal. "IBM has the most market momentum of any server vendor out there."
Neterion also has signed deals with HP, Silicon Graphics and Sun.
Neterion, formerly called S2io, is one of the companies trying to make 10Gb Ethernet a reality. Most servers today come with 1Gb Ethernet, while personal computers generally are another step down with 100Mb Ethernet.
Such transitions take years, though. Faster networking usually first catches on to connect high-end switches before propagating to servers and eventually to mainstream computers.
The internal data traffic within IBM's x460 is managed by a chipset called x3. One feature of the servers is virtual input-output — a feature that makes it possible to shift networking resources assigned to software without disrupting that software.
That virtualisation ability in x3 dovetails with a similar ability in the Neterion adapters, Zabrowski said. The total 10Gbps capacity of the adapter can be sliced up in any of eight different ways, for example, to be assigned to different independent partitions of a server.
"You can assign a certain amount of bandwidth uniquely to those partitioned workloads. The partitions don't even know they're sharing the adapter," Zabrowski said. And the capacity allocations can be changed on the fly, he added.
