Arista 7170 Series Network Switch - Quick Look

Arista 7170 Series Introduction

Highly dynamic cloud data center networks continue to evolve with the introduction of new protocols and server technologies. The Arista 7170 series are purpose built, programmable fixed configuration data center switches for flexible, dense 100GbE solutions at spine layer and 25/50GbE solutions for storage and compute.

Combining Arista EOS and a highly programmable switch architecture with customizable system resources, the 7170 Series delivers unique features for traditional and new network based applications and services.

7170 Series Deployment Scenarios

With 32 and 64 port QSFP100 port fixed configuration systems in compact form factors, the 7170 series are 100GbE systems that can support a flexible combination of up to 64x 40/100GbE, 128x 50GbE or 256x 10/25GbE of wire speed performance powered by Arista EOS, the worlds most advanced network operating system.

The 7170 series supports a unique programmable pipeline with the flexibility to change the packet parser dynamically through profiles defined in P4, to add new functionality, vary table sizes and order of operations. This provides phenomenal investment protection along with opening the possibility to support highly personalized use cases to solve traditional and new network challenges which are otherwise not feasible with traditional switching platforms. The following are a selection of such use cases

• Network Services Offload

  in a bare metal environment freeing up compute resources and accelerating applications.

• Tunnel Termination

  in a multi-tenant design.

• Large Scale NAT

  for address and port translation.

• Flexible Routing

  to support MPLS label modification or custom protocols.

• Network and Application Telemetry

  with flow level visibility, timestamping and end to end latency measurement.

• Network Security

  with stateful and hierarchical ACLs, rule based policies, and conditional filtering for enhanced security and application monitoring.

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.

7170 Series Systems

Arista 7170 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, network security, application level performance monitoring and virtualization.
