Extreme looks to one-up Cisco, others in data center

LAS VEGAS - At Interop this week, Extreme Networks rolled out two new switches designed to migrate users from legacy data center infrastructures into cloud computing environments. 

Extreme unveiled the BlackDiamond X8 for the data center core, and the Summit X670 for the top of the server rack. Together the switches are the underpinning of Extreme's Open Fabric, a data center switching plan that embraces standards and partnerships to take customers to the cloud.

The BlackDiamond X8 takes up one-third of a data center rack. It has a switching capacity of over 20Tbps or 1.28Tbps per slot. It can support 768 wire-speed 10G Ethernet ports - which is industry-leading density - and 192 wire-speed 40G Ethernet ports, Extreme says.

Port-to-port latency on the X8 is less than 3 microseconds, Extreme says. It consumes 5 watts per 10G port and supports 128,000 virtual machines, the company says. The switch supports a new architecture for Extreme, in that the mid-plane is reserved only for management traffic; business data never crosses the mid-plane. I/O modules connect directly to the switch's fabric modules for increased performance, Extreme says.

The Summit X670 comes in two versions: the X670 and the X670V. The X670 is a 48-port 10G switch while the X670V adds a four-port 40G uplink capability, or another 24 ports of 10G.

Both switches support 128,000 virtual machines, the IEEE's Data Center Bridging standard for lossless Ethernet operation and data and storage integration, and the Multi-System Link Aggregation specification to flatten the Ethernet fabric for high performance, low latency and high resiliency.

Indeed, M-LAG is a key component of Extreme's Open Fabric initiative. Extreme is proposing this method as an alternative, for now, to the IETF's TRILL and the IEEE's Shortest Path Bridging for flattening data center switching architectures

Other components of Extreme's Open Fabric are support for the IEEE's 802.1Qbg standard which, among other capabilities, includes Virtual Ethernet Port Aggregation (VEPA) for allowing physical switches to off-load some processing from virtual switches on servers; and support for VM mobility management in its Extreme XOS operating system.
