Overview

The Arista 7020R Series, including the 7020SR, 7020SRG, 7020TR and 7020TRA, o ers

a purpose built high performance and power e cient solution for high density data

center deployments. With a choice of 10G SFP+ or 100/1000Mb RJ45, the switches

deliver non-blocking forwarding of up to 1.04 Tbps combined with feature rich L2

and L3 switching. A natural extension to the 7280R Series, the 7020R are members of

the Arista portfolio of data center switches.

With broad support for QoS, security, automation and monitoring features, the

7020R provides an ideal solution to the challenges of implementing network policy

consistently in both 1G and 10G environments when combined with the Arista xed

con guration 7280R Series 10 and 40 Gigabit switches. The 7020R deliver the

exibility to be deployed as the server edge of 1Gb Ethernet leaf and spine designs

or as a high performance storage network switch. Arista EOS advanced automation,

monitoring and provisioning features are consistent to all Arista switches,

eliminating the complexity associated with managing mixed environments with

inconsistent feature sets. The 7020R Series deep packet bu ers and large forwarding

tables allow for a broad set of networking applications.

The 7020SR and 7020SRG provide SFP+ ports for both 1G or 10G connections and 2

ports of 100G with a full range of optics and cables. The 7020TR and 7020TRA both

provide 48 100/1000Mb RJ45 ports and 6 SFP+ ports for both 1G or 10G uplink

connections with a full range of optics and cables. The Arista 7020R switches o er

low latency and a deep packet bu er of up to 3GB that is fully shared and allocated

dynamically to ports that are congested. Consuming under 1W per gigabit, the

7020R are power e cient with choices of AC and DC power, hot-swap power

redundancy along with redundant fans supporting either forward or reverse air ow

in a single system.

Combined with Arista EOS, the 7020R Series delivers advanced features for big data,

cloud, virtualized and traditional designs together with enhancements for video

streaming, media and entertainment.

Arista EOS

The Arista 7020R Series runs the same Arista EOS software as all Arista products,

simplifying network administration. 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.

With Arista EOS, advanced monitoring and automation capabilities such as Zero

Touch Provisioning, LANZ, VMTracer and Linux based tools can be run natively on

the switch with the powerful x86 CPU subsystem.
