Arista 7300X3 Series Introduction

The Arista 7300X3 Series are the benchmark for performance, scale and power efficiency in modular data center and campus switches. Adoption of 25G servers is accelerating the need for flexible, dense 100GbE/40GbE solutions with support for both 10GbE and 25GbE speeds. The Arista 7300X3 Series extends the industry leading 7300 Series with increased performance, scalability, density and features designed for software driven cloud networking.

The Arista 7300X3 Series are a range of modular systems, a 4-slot and 8-slot, with a choice of 10/25GbE and 100GbE line cards for high performance, low latency and scalable multilayer switching powered by Arista EOS, the worlds most advanced network operating system.

7300X3 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.

The 7300X3 Series are ideal for a number of deployment scenarios inside the data center. With a choice of systems each capable of high density 100G and 40G they are ideal for use as a single tier collapsed leaf and spine or at the spine layers of two-tier networks. The Arista universal network architecture is optimized for all application types ranging from large cloud to enterprise deployments.

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

7300X3 Network Switch Deployment Scenarios

The following are a selection of use cases:

  • Collapsed Spline™

    — Server access as middle of row or end of row supporting full range of, 10G, 25G and 100G connection options

  • Leaf-Spine

    — Open standards based L2 and L3 with monitoring and visibility features — LANZ, DANZ, Tracers

  • ECMP Designs Up to 128-way

    — Cost-effective 100GbE multi-pathing using open protocols

  • Cloud Scale Modular Switch

    — With high availability features and choice of 40G and 100G density up to 256 x 40G or 100G and full L2 and L3 features

  • Consolidated Campus

    — Core and aggregation layers with collapsed Spline™ approach to build simple single tier with high availability

  • Grid / HPC

    — Designs requiring cost effective and power efficient systems to enable non-blocking or minimal over-subscription

  • Spine for Hadoop

    — Big data applications with east-west connectivity

  • Directly Connected 25GbE, 40GbE and 50GbE 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.

7300X3 Series Systems

Arista 7300X3 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.
