7170 Series | Model Overview

Model Overview

The 7170-64C is a 2RU system with 64 100G QSFP ports offering

wire speed performance with an overall throughput up to 12.8 Tbps.

Each QSFP port is capable of a choice of 100GbE, 40GbE, 4x10GbE,

4x25GbE or 2x50GbE with hitless configuration change between

modes. The 64 QSFP ports can be broken out to a system maximum

of 256 ports allowing for easy transitions and maximum flexibility

enabling deployment as both a leaf and spine. The two integrated

SFP+ ports provide additional high speed connections for

management networks and out of band monitoring.

Maximum Flexibility for Scale Out Network Designs

Scale out network designs enable solutions to start small and evolve over time. A simple two-way design can grow as far as 128-way

without significant changes to the architecture. The Arista 7170 include enhancements for flexible scale-out designs:

• 128-way ECMP and 64-way MLAG to provide scalable designs and balance traffic evenly across large scale 2 tier leaf-spine designs

• Equal Cost Multi-Pathing (ECMP) for traffic balancing in large scale multi-tier topologies

• Custom hash algorithms for efficient hashing, persistent hashing and custom lookups for tunneled protocols *

• Flexible allocation of forwarding table resources for more design choice

• Wide choice of dense 10G/25G/40G/100G interfaces for multi-speed flexibility

• VXLAN routing, bridging and gateway capability for physical to virtualization communication in next generation data center designs

• DANZ, sFlow and multi-port mirroring to detect micro-burst congestion and provide network wide visibility and monitoring

• Hitless speed changes from 10G to 100G to eliminate down-time when implementing speed changes

• AlgoMatch to match business intent to network policy for flow matching, access control and telemetry

• Network Address Translation for network merging, address hiding for security and application scaling

• EOS tools for network wide visibility and monitoring to detect traffic bursts, monitor latency and congestion and allow capacity

planning to improve application performance and availability

High Availability

The Arista 7170 Series were designed for continuous operations

with system wide monitoring of both hardware and software

components,

simple serviceability and provisioning to prevent

single points of failure. Key high availability features include:

• 1+1 hot-swappable power supplies and four hot-swap fans provide

dynamic temperature control combined with N+1 redundancy

• Color coded PSU’s and fans that deliver platinum level power

efficiency

• Live software patching

• Self healing software with Stateful Fault Repair (SFR)

• Smart System Upgrade (SSU) and Accelerated Software Update

The 7170-32C and 7170-32CD are 1RU systems with 32 100G

QSFP ports offering wire speed performance with an overall

throughput up to 6.4 Tbps. Each QSFP port is capable of a choice of

100GbE, 40GbE, 4x10GbE, 4x25GbE or 2x50GbE with hitless

configuration change between modes. The 32 QSFP ports can be

broken out to a system maximum of 128 ports allowing for easy

transitions and maximum flexibility enabling deployment as both a

leaf and spine. The two integrated SFP+ ports provide additional

high speed connections for management networks and out of band

monitoring.
