Extreme Boosts Network Switch Line
New management module adds high-end resiliency features.Extreme Networks Inc. demonstrated its continued commitment to its five-year-old Black Diamond network switch line with a new management module that adds high-end resiliency features. The new MSM-3 management module, which is backward compatible with existing line cards for the Black Diamond 6800 modular switch, adds "hitless failover" in the event of an outage or performance hiccup as well as the ability to upgrade software for the switch without having to take the network down, according to Duncan Potter, vice president of marketing for the Santa Clara, Calif., networking vendor. "Should a failure occur, we can fail over without significant packet loss. And were adding further capability to upgrade software without having to reboot the device," he said. Competing network switcheswith the exception of very high-end core Internet routersrequire a reboot, which must be scheduled during off hours to avoid network downtime.
For large networks supporting a variety of users, even a few minutes of downtime to reboot a switch can be too much, believes Robert Jacobs, director of network services at Phonoscope Ltd., a Houston, Texas, network services provider.
