Dense wave division multiplexing, or DWDM, which allows for increased capacity and throughput, supports the kind of high-bandwidth, low-latency needs of business-continuity applications as well as the high service density that storage requires, the company said. With network services growing, an enterprise can scale the network without interruptions. "Were seeing applications skyrocketing across these networks today," said Geraint Anderson, vice president of EMEA at Cisco.
With DWDM, an enterprise not only can consolidate storage networks but also can use its fiber capacity more efficiently. "This product is setting the standard for enterprise DWDM," Anderson said.
Lucents new OptiStar Edge Switch, meanwhile, will scale down to optical carrier level 3, which has a capacity of 155M bps, later this month starting at about $35,000. Current versions are for more elite enterprises and service providers, transmitting at OC-12 (622M-bps) and OC-48 (2.5G-bps) speeds, said Jeff Shafer, product manager, in Murray Hill, N.J. Using technology licensed from Bothell, Wash.s Vixel Corp., the updated switch has hardware flow control and holds both dual-channel Fibre Channel over IP (FCIP) cards and Gigabit Ethernet cards, Shafer said. It connects to SANs using 1G-bps Fibre Channel, while 2G-bps versions are on the road map, he said. The switch will get support for SNMP 2.0 later this month, he said. OptiStar is certified for Broomfield, Colo., McData Corp.s SAN switches, but "well commit to working with customers regardless of what Fibre Channel switches they have," Shafer said, referring to McData competitors like San Jose, Calif.s Brocade Communications Systems Inc. Nortel offers mainstream enterprises the Optera Metro 5100 and 5200 series. "We believe this is a big market opportunity. We are working at enabling lower-cost solutions. SONET and SDH is what were looking at for the future," Product Manager J.C. Fahmy said, in Brampton, Ontario. Nortel will announce details soon, he said, declining to elaborate.
SONET multiplexers are as cheap as $11,000, said analyst Sterling Perrin, of International Data Corp. Regardless of which technology or supplier users pick, "its not like theres major pitfalls. Its just fairly complex technology. Many enterprises are still unfamiliar with the technology, even at the large enterprises," Perrin said. But, "Obviously the SANs have limitations for how far you can extend that traffic. You need another wide-area technology to do that." Most Recent Storage Stories: Find white papers on storage.
