Catalyst Gets Older
Because it handles so many jobs -- Ethernet! Firewalls! Load balancing! Checkbook balancing! -- Catalyst gets likened to a Swiss army knife. It keeps that job under the Nexus regime, but Catalyst is coming up on some limitations, not surprising given its age.
Specifically, it's unclear whether a card with 100-Gbit/s interfaces is in Catalyst's future.
"We think we can build it, but we don't think it would be a high-performance module because of the limitations of the Catalyst backplane," says Deepak Munjal, marketing manager for Cisco's data center team. "It's something we're thinking about."
