Arista 7020SR, 7020SRG, 7020TR, 7020TRA Datasheet
Overview
The Arista 7020R Series, including the 7020SR, 7020SRG, 7020TR and 7020TRA, oers
a purpose built high performance and power ecient 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 1.04Tbps 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
conguration 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 buers 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 oer
low latency and a deep packet buer 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 ecient with choices of AC and DC power, hot-swap power
redundancy along with redundant fans supporting either forward or reverse airow
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.

7020R Series | Platform Overview
Software Dened Cloud Networks
Arista Software Dened Cloud Networking (SDCN), combines the principles that have made cloud computing the unstoppable force
that it is: automation, self service provisioning, and linear scaling of both performance and economics coupled with the trend in
Software Dened Networking that delivers: network virtualization, custom programmability, simplied architectures, and lower capital
expenditure. This combination creates a best-in-class software foundation for maximizing the value of the network to both the
enterprise and service provider data center.
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 signicant changes to the architecture. The Arista 7020R include enhancements that allow for exible scale-out designs:
•
24 ports of 1/10G or 48 ports of 1G RJ45 to provide scalable designs and balance trac evenly across large 2 tier leaf-spine designs
•
Comprehensive L2 and L3 forwarding table resources for more design choice
•
VXLAN gateway, bridging and routing with VMTracer features to enable next generation data center designs *
•
Virtual output queue (VoQ) architecture and deep packet buering to eliminate head of line blocking with low latency
•
Wide choice of both 1G, 10G and 40G/100G transceivers and cables for single port multi-speed exibility
•
Integrated packet capture, sFlow and multi-port mirroring provide network wide visibility and monitoring to detect trac bursts,
monitor latency and congestion and allow capacity planning to improve application performance and availability *
Advanced Event Management (AEM)
Simplifying the overall operations, AEM provides the tools to customize alerts and actions. AEM is a powerful and exible set of tools to
automate tasks and customize the behavior of EOS and the operation of the overall data center switching infrastructure. AEM allows
operators to fully utilize the intelligence within EOS to respond to real-time events, automate routine tasks, and automate actions based
on changing network conditions.
CloudVision
CloudVision is a network-wide approach for workload orchestration and workow automation as a turnkey solution for Cloud
Networking. CloudVision extends the EOS publish subscribe architectural approach across the network for state, topology, monitoring
and visibility. This enables enterprises to move to cloud-class automation without needing any signicant internal development.
Next Generation Provisioning and Monitoring
Zero Touch Provisioning (ZTP) combined with other Arista features, like VMTracer's adaptive VLAN conguration allows data center
managers to fully automate the bring-up of network elements and virtual servers and leverage Arista's unique 'hands-o ' provisioning.
Designed to integrate with VMware, OpenStack and Microsoft OMI, Arista’s open architecture allows for integration with any
virtualization and orchestration system providing visibility to the VM-level enabling portable policies, persistent monitoring and rapid
troubleshooting of cloud networks.
7020R Deterministic Network Performance
The Arista 7020R Series uses a deep buer virtual output queue (VOQ) architecture that eliminates head-of-line (HOL) blocking and
virtually eliminates packet drops even in the most congested network scenarios. An advanced trac scheduler fairly allocates
bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, xed
priority, or hybrid schemes. As a result, the Arista 7020R can handle the most demanding data center requirements with ease, including
mixed trac loads of real-time, multicast, and storage trac while still delivering low latency.
Virtualization
Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation
technologies such as VXLAN. The 7020R builds on the valuable tools already provided by the Arista VM Tracer suite to integrate directly
into encapsulated environments. Oering a wire-speed gateway between VXLAN and traditional L2/3 environments, the 7020R makes
integration of non-VXLAN aware devices including servers, rewalls and load-balancers seamless and provides the ability to leverage
VXLAN as a standards based L2 extension technology for non-MPLS environments.
