Cisco is about to unleash a new switch on the world. It sounds like an absolute beast.:
The Nexus brings Cisco into not just a new territory for its business, but a new product category: a unified switch that spans storage and computing in data centers and has security built in. Given the stakes, superlatives are natural.
– A single Nexus chassis will be able to handle more than 15Tbps of traffic ripping through a data center, up from just 2Tbps for a current Catalyst 6500 switch.
– At that rate, the switch could run 5 million concurrent transcontinental conferencing sessions using Cisco’s TelePresence Collaboration system. It could also copy the entire searchable Internet in 7.5 minutes.
– One interface module for the Nexus 7000 chassis will come with 32 10Gbps ports, and the platform is designed to support future interfaces including 100Gbps.
– The company spent about $250 million on research and development for the new platform, and at its peak, the Nexus R&D team numbered more than 500 engineers, according to Tom Edsall, senior vice president and chief technology officer of Cisco’s Data Center Business Unit.
As with the Catalyst 6000 Series and the CRS-1, Cisco developed the Nexus with an eye to long-term needs. Where the CRS marked the debut of IOS XR, the first modular version of IOS, the Nexus will have Cisco’s first OS that can be fully virtualized, called NX-OS. The Nexus will also break new ground with its lossless switching fabric, a departure from traditional Ethernet — though backward compatible with it, Cisco said.
It looks great too:
