Arista 7050X3 Series Introduction

Highly dynamic data center networks continue to evolve with the introduction of new protocols and server technologies such as containers bringing with them ever increasing bandwidth demands, accelerating the need for dense 25 and 100 Gigabit Ethernet switching in both leaf and spine tiers of modern networks. The Arista 7050X3 Series are purpose built fixed configuration 10/25GbE and 100GbE systems built for the highest performance environments, and to meet the needs of the largest scale data centers. They combine scalable L2 and L3 resources and high density with extensive automation and programmability capabilities, low latency and consistent features for scalable leaf-spine designs.

7050X3 25GbE and 100GbE Flexibility

The 7050X3 Series are a range of compact 1U wire speed switches with a choice of 25GbE SFP with 100GbE QSFP uplinks and a 100GbE system that offer up to 32 ports of wire speed forwarding, powered by Arista EOS, the worlds most advanced network operating system.

The 7050X3 Series is available in a choice of three models:
  • 7050CX3-32S - 10/25/40/50/100GbE connectivity with 32 100G QSFP interfaces
  • 7050SX3-48YC12 - 48 10/25GbE SFP interfaces with 12 100G QSFP interfaces
  • 7050SX3-48YC8 - 48 10/25GbE SFP interfaces with 8 100G QSFP interfaces

Consistent Software, Flexibility, Throughput and Performance


Each of the 7050X3 models offers multiple connectivity options that provide flexibility in building scalable leaf and spine designs. The operational flexibility offered by the entire 7050X3 series ensures suitability for a variety of deployment scenarios. The following are a selection of use cases:

  • Dense Top of Rack

    — For server racks with both 10GbE and 25GbE systems
  • 10GbE to 25GbE Migration

    — 802.3by 25GbE and Consortium compliant for seamless transition to the next generation of Ethernet performance
  • Grid / HPC

    — Designs requiring cost effective and power efficient systems to enable non-blocking or minimal over-subscription for 10G and 25G Servers
  • Leaf-Spine

    — Open standards based L2 and L3 with telemetry and visibility features
  • 100GbE Scale Out Designs

    — Small to medium locations requiring power efficiency and high density compact systems
  • ECMP Designs up to 128-way

    — Cost-effective multi-pathing using open protocols and the Arista 7300X and 7500R as 100GbE modular spine switches
  • Large Scale L2 Environments

    — Flexible resource allocations achieve higher maximum L2 scale without inefficiency associated with traditional systems

7050X3 Series Systems

Arista 7050X3 Series support hot-swappable power supplies and N+1 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.

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.
