Arista Scales its Flagship Switch


Arista Networks announced significant enhancements enabling its flagship Arista 7500 modular switching platform to scale to support over 100,000 servers and millions of virtual machines.  The Arista 7500E offers 1,152 10GbE, 288 40GbE, or 96 100GbE wire-speed ports.


Key improvements of the Arista 7500E compared to the first generation Arista 7500:

  • Three times the fabric bandwidth at 30 Terabits per second
  • Three times the packet buffer at 144 Gigabyte per switch
  • Three times the control plane performance
  • Triple the power efficiency at less than 4 watts per 10GbE port
  • The industry’s first triple-speed 10/40/100GbE line card. It features integrated MXP (multi-speed-port) optics that can be software configured on a per port basis delivering constant price-per-bandwidth at every port speed. 
  • Much larger L2 and L3 Table Sizes
  • Wirespeed VXLAN capability on every port

Entry level US list prices start at $99,995 for the switch and $10,000 per 100GbE port, $2,200 per 40GbE and under $600 per 10GbE port.

In a leaf-spine data center architecture, using the Arista 7500E as the spine and Arista 7150/7050 as the leaf, Arista said the network  can support more than 100,000 servers that deliver consistent performance for dynamically scaling workloads in public or private clouds, including Hadoop, Big Data, storage, Web 2.0, VM farms, and network virtualization.
SDN capabilities include fuctioning as wirespeed VXLAN gateways that enable multi-tenant network virtualization.  Arista also supports Rapid Automated Indication of Link-Loss (RAIL) for accelerated convergence in Big Data analytics and Hadoop applications.

“The 7500E Series is a major engineering achievement, offering the industry’s highest throughput and three times the capability of the original Arista 7500 in every dimension - performance, density and power without a chassis upgrade,” said Andreas Bechtolsheim, Arista’s Chairman and Chief Development Officer. “It enables customers to build the world’s largest switching infrastructures that handle the most demanding workloads with ease.”
