FAST, FASTER, FASTEST: Internet2 readies 100G OpenFlow SDN for Big Data
The advancements, announced at the Brocade Technology Day here, are intended to support cloud environments with thousands of virtual machines running within and between data centers. The chassis switch complies with Brocade's VCS Ethernet fabric, which was developed to provide a lossless, low latency, deterministic multi-path Ethernet network based on the TRILL specification in the forwarding plane.
The new wares will undoubtedly heat up the fabric switching competition between Brocade and Cisco, HP and Juniper. But none of these players yet has introduced a high-density 100G Ethernet switches for the data center core -- Cisco's play is believed to be startup and potential spin-in Insieme Networks. And to date, Huawei is the only major vendor to have shown a high-density 100G Ethernet switch.
Brocade, the leader in FibreChannel storage-area network switching, is looking to maintain its hold on the data center as competitors -- and Brocade as well -- offer converged Ethernet LAN, storage and compute systems. In its effort on this front, Brocade acquired Ethernet switch vendor Foundry Networks in 2008 but maintains a less than 2% share of the overall market.
Perhaps Brocade's new switches will up that share. The new VDX 8770 chassis switch (pictured above) tops off the VCS-capable VDX switching line from Brocade. It includes 8-slot and 4-slot chassis supporting 4Tbps per slot, Brocade says. The switch was two years in development and was initially expected to ship last year.
At 4Tbps, the 8770 could theoretically support 40 100G Ethernet ports per slot (if physical real estate on a module will allow), or perhaps more than 300 per 8-slot chassis. Brocade would not disclose the 100G densities it is aiming for but said 100G modules for the 8770 will be rolled out in the next 12-18 months.
That capacity could also conceivably support 400 10G and 100 40G ports per slot. But at first ship, the VDX 8770 will support 48-port Gigabit Ethernet, 48-port 10G and 12-port 40G line cards, all at line rate, Brocade says.
The VDX 8770 also features 3.5 microsecond port-to-port latency, and can tunnel VXLAN and NVGRE network virtualization traffic at line rate, the company says. In addition to TRILL support for Layer 2 multipathing, the VDX 8770 also supports Brocade Trunking for Layer 1 resiliency and a technique for Layer 3 multipathing as well.
