7050X3 MACsec | Platform Overview

Software Driven Cloud Networking

Arista Software Driven 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. A new architecture for the most mission-critical location within the IT infrastructure that

simpli es management and provisioning, speeds up service delivery, lowers costs and creates opportunities for competitive

di erentiation, while putting control and visibility back in the hands of the network and systems administrators.

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 7050CX3M include enhancements for exible scale-out designs:

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

• Equal and Unequal Cost Multi-Pathing (UCMP) for exible tra c balancing in large scale multi-tier topologies

• Custom hash algorithms for e cient hashing, persistent hashing and custom lookups for tunneled protocols

• Flexible allocation of L2 and L3 forwarding table resources for more design choice

• Wide choice of dense 10G/25G/40G/50G/100G interfaces for multi-speed exibility

• Support for standards based IEEE 25GbE for simple and cost e ective migration from 10G and 40G to 25G and 100G

• 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

Uni ed Forwarding Table

Network scalability is directly impacted by the size of a switches forwarding tables. In many systems a 'one size ts all' approach is

adopted using discrete xed size tables for each of the common types of forwarding entry. The Arista 7050X3M leverage a common

Uni ed Forwarding Table (UFT) for the L2 MAC, L3 Routing, L3 Host and IP Multicast forwarding entries, which can be partitioned per

entry type. The ideal size of each partition varies depending on the network deployment scenario. The exibility of the UFT coupled

with the range of pre-de ned pro les available on the 7050X3 ensures optimal resource allocation for all network topologies and

network virtualization technologies.

Enhanced Features for High Performance Networks

The Arista 7050X3M series deliver a suite of advanced tra c control and monitoring features to improve the agility of modern high

performance environments, with solutions for data monitoring, and next-generation virtualization.

Automating the data center enables customers to dynamically provision computing resources in the most e cient manner while also

meeting business needs by maintaining service level agreements (SLAs). Arista EOS automates complex IT work ows and simpli es

network operations while reducing or even eliminating downtime. Arista EOS rich automation capabilities not only reduce the human

error element in network operations but also enable IT operators to make the network work the way they want.

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.

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.
