Arista 7300X Series Introduction

The Arista 7300 Series are the benchmark for performance, scale and power efficiency in modular data center switches. Increased adoption of 10G servers is accelerating the need for flexible, dense 10GbE/40GbE solutions. The Arista 7300 Series Switch extends the industry leading 7000 Series with increased performance, scalability, density and features designed for software defined networking.

The Arista 7300 Series are a range of modular systems, a 4-slot and 8-slot, with a choice of three 10GbE and 40GbE linecards for high performance, low latency and scalable multilayer switching powered by Arista EOS, the worlds most advanced network operating system.

7300 Deployment Scenarios

Scale out network designs allow solutions to start small and expand over time; simple highly scalable one and two-tier network designs are built with MLAG, ECMP and VXLAN technologies.

Cloud Networking: 2-tier Leaf/Spine or 1-tier Collapsed Spine

Network Programability

The 7300 Series are ideal for a number of deployment scenarios inside the data center. With a choice of three systems each capable of 10G and 40G they are ideal for use as a single tier collapsed leaf and spine or at both the leaf and spine layers of two-tier networks. The Arista universal network architecture is optimized for all application types ranging from large cloud to enterprise deployments. The following are a selection of use cases:
  • Collapsed Spline™ Server

    — access as middle of row or end of row supporting full range of 1G, 10G and 40G connection options
  • Leaf-Spine

    — open standards based L2 and L3 with monitoring and visibility features — LANZ, DANZ, Tracers
  • ECMP designs up to 64-way

    — cost-effective 8 way multi-pathing using open protocols and 7050X or 7060X as spine and 64-way using 7300X
  • Software Defined Networking

    — with support for OpenFlow, DirectFlow, eAPI and VXLAN
  • Enterprise Modular Switch

    — with high availability features and choice of 40G and 10G density up to 256 x 40G or 1024 x 10G and full L2 and L3 features
  • Grid / HPC

    — designs requiring cost effective and power efficient systems to enable non-blocking or minimal over-subscription
  • Spine for Hadoop and Big Data Applications

    — with east-west connectivity
  • Directly connected 40GbE Attached Storage

    — dense NFS systems, requiring high performance and predictable latency

Arista EOS

Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.

7300 Series Systems

Arista 7300 Series support redundant hot-swappable power supplies, fabric and fan redundancy, EOS high availability, a choice of L2 and L3 multi-pathing designs and powerful EOS innovations for visibility, application level performance monitoring and virtualization.
