7050QX Series | Platform Overview

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 64-way

without signi cant changes to the architecture. The Arista 7050QX include enhancements that allow for exible scale-out designs:

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

• 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/40G ports for single port multi-speed exibility

• VXLAN routing, bridging and gateway for physical to virtualization communication to enable next generation data center designs

• DANZ, sFlow and multi-port mirroring to detect micro-burst congestion and provide network wide visibility and monitoring

Software De ned Networking

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. 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.

Smart System Upgrade

Smart System Upgrade is a network application designed to address one of the most complicated and challenging tasks facing data

center administrators - network infrastructure maintenance. Changes to the underlying network infrastructure can a ect large numbers

of devices and cause signi cant outages. SSU provides a fully customizable suite of features that tightly couples data center

infrastructure to technology partners allowing for intelligent insertion and removal, programmable updates to software releases and

open integration with application and infrastructure elements.

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.

Enhanced Features for High Performance Networks

The Arista 7050QX 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.

Precise Data Analysis

Arista Latency Analyzer (LANZ) is an integrated feature of EOS. LANZ provides precise real-time monitoring of micro-burst and

congestion events before they impact applications, with the ability to identify the sources and capture a ected tra c for analysis.

Virtualization

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation

technologies such as VXLAN. The 7050QX 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 7050X

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.

Uni ed Forwarding Table

Cloud 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 7050X leverages a common

Uni ed Forwarding Table 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 con guration pro les available on the 7050X ensures optimal resource allocation for all network topologies and

network virtualization technologies.
