7020R Series | Platform Overview

Software De ned Cloud Networks

Arista Software De ned 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 De ned Networking that delivers: network virtualization, custom programmability, simpli ed 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 signi cant 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 tra c 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 bu ering 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 tra c 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 work ow 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 signi cant internal development.

Next Generation Provisioning and Monitoring

Zero Touch Provisioning (ZTP) combined with other Arista features, like VMTracer's adaptive VLAN con guration 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 bu er 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 tra c 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 tra c loads of real-time, multicast, and storage tra c 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. O ering 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.
