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.

AlgoMatchTM
AlgoMatch is a unique Arista innovation for modern cloud networks, combining both software and hardware to enable more exible
and scalable solutions for access control, policy based forwarding and network telemetry. By combining general purpose memory with
advanced software algorithms AlgoMatch delivers higher scale, performance and eciency with lower power and is more cost
eective than traditional solutions. AlgoMatch provides a more ecient packet matching algorithm that in turn enables ow matching
for access control, policy and visibility. The net benets are a high performance policy engine with both increased functionality and
scale in a cost and power ecient solution. AlgoMatch is available on the 7020RA Series of products.
Secure Encryption with IPSec (7020SRG-24C2 Only)
The 7020SRG includes support for high performance IPSec. IPSec ensures the protection of sensitive information between participating
IPsec devices. IPsec is a framework of open standards, developed by the IETF, that provides security for the transmission of sensitive
information over unprotected network by encrypting the data. IPSec acts at the network layer, protecting and authenticating IP packets
between participating IPSec devices. 7020SRG IPSec is optimized for site to site VPNs, for example to a POP or a backup datacenter
location, with support for AES-256 and SHA-256 secure public key encryption.
IPSec encryption is an EOS licensed feature and requires a license le to enable the encryption feature. License information is included
in the ordering information section of this document.
7020R Accelerated sFlow
SFlow is a powerful tool used commonly by network operators for advanced network telemetry, capacity planning, security analysis
and quality of experience monitoring. All models of the 7020R Series enable sFlow utilizing the high performance CPU. Within modern
high performance systems trac sampling requires the capability to both sample and process packet rates of hundreds of millions of
packets per second. With the 7020R Series Accelerated sFlow feature the sampling and processing of ow samples into sFlow
datagrams is handled via an sFlow engine capable of generating high rate sFlow data, and of supporting 1:1000 sampling rates of full
wire speed systems or higher rates with selective sampling based on triggers and lters. All sFlow v5 information is included in the
sFlow records ensuring consistent integration with existing standard sFlow collection and analysis tools and no loss of information.
EOS Software Licensed Features
Arista EOS delivers a comprehensive feature set along with single image consistency with all other Arista switches. The default EOS
