QLogic boasts 20Gbit/s Infiniband card

QLogic Corp. finally rolled out its first 20Gbit/s Infiniband adapter card. It said this will be followed by a 40Gbit/s card later this year based on a new version of its TrueScale ASIC. Based on reports, QLogic goes toe-to-toe with Mellanox Technologies, which had been the sole supplier of the fastest Infiniband silicon and cards to date.

"Our customers are looking for an alternative supplier. The market will not expand as readily without another card supplier that is fully vertically integrated," said Amit Vashi, VP marketing for server card group, QLogic.

Infiniband has been slowly on the rise as a system-to-system interconnect, gaining traction mainly as a link in high-performance clusters. As clusters expand to handle more applications, this has grown, often replacing proprietary links. International Data Corp. pegs the market for Infiniband cards at about $120 million in 2008 rising to nearly $300 million in 2011.

QLogic reported its series 7200 cards are at par with those from Mellanox in terms of raw bandwidth and latency. "In some areas, like their ability to carry as many as 26 million clustering messages per second, they surpass the Mellanox products," QLogic said. The company added that its products do a superior job of carrying more messages and keeping latency low as users add more systems to a cluster.

The 20Gbit/s cards available will sell for about $600 to end users. QLogic would not quote volume prices to OEMs.

The cards are the result of the company's February 2006 acquisition of startup Pathscale, which sold a 2.5Gbit/s Infiniband card that rode the HyperTransport bus. About 18 months ago, the company rolled out a similar card for the PCIe bus. Its upcoming quad-data-rate card will ride the 5GHz version of Express.
