7500 Series - Scalability

Flat Layer-2 MLAG Spine - All Active Multipathing

  • Standards based protocols (LACP)
  • Eliminates Spanning Tree from the topology
  • Simple to understand and easy to deploy

ECMP - All Active Multipath for Layer 3

  • Standards based protocols (OSPF, IS-IS, BGP)
  • Eliminates L2 for exceptional scalability and fault tolerance
  • Exceptional scale with consistent performance in 2 tiers

VXLAN - Layer 2 over Layer 3 - Best of both worlds

  • Active multipath using ECMP (up to 64-way)
  • Single L3 network for all applications
  • L2 extensions for stateful VM - VM over Layer 3
  • Extends L2 with exceptional scalability (16 million virtual networks)

Arista 7500 Series Technical Architecture

The Arista 7500E Series is designed with the latest in switching silicon and software.

The unique fabric and deep buffer virtual output queue (VOQ) architecture eliminates head-of-line (HOL) blocking and virtually eliminates packet drops even in the most congested network scenarios. The Arista 7500 can handle the most demanding data center requirements with ease, including mixed traffic loads of real-time, multicast, and storage traffic.
