7050X3 Series | Platform Overview
Dynamic Buer Allocation
In cut-through mode, the Arista 7050X3 switches forward packets with a consistent low latency of 800 nanoseconds. Upon congestion,
the packets are buered in an intelligent fully shared packet memory that has a total size of 32MB for superior burst absorption. Unlike
other architectures that have xed per-port packet memory, the 7050X3 Series use dynamic thresholds to allocate packet memory
based on trac class, queue depth and quality of service policy ensuring a fair allocation to all ports of both lossy and lossless classes.
Buer utilization, occupancy and thresholds are all visible with Arista LANZ and can be exported to monitoring tools to identify
hotspots and measure latency at the device and end to end.
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 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. A new architecture for the most mission-critical location within the IT infrastructure that
simplies management and provisioning, speeds up service delivery, lowers costs and creates opportunities for competitive
dierentiation, 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 signicant changes to the architecture. The Arista 7050X3 include enhancements for exible scale-out designs:
•
128-way ECMP and 64-way MLAG to provide scalable designs and balance trac evenly across large scale 2 tier leaf-spine designs
•
Equal and Unequal Cost Multi-Pathing (UCMP) for exible trac balancing in large scale multi-tier topologies
•
Custom hash algorithms for ecient 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 eective 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
Unied 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 7050X3 leverage a common
Unied 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-dened proles available on the 7050X3 ensures optimal resource allocation for all network topologies and
network virtualization technologies.
Enhanced Features for High Performance Networks
The Arista 7050X3 series deliver a suite of advanced trac 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 ecient manner while also
meeting business needs by maintaining service level agreements (SLAs). Arista EOS automates complex IT workows and simplies
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 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.
7050X3 Series | Platform Overview
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.
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 aect large numbers
of devices and cause signicant 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.
Virtualization
Supporting next-generation virtualized data centers requires tight integration with orchestration tools and encapsulation technologies
such as VXLAN. The 7050X3 build 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, they make integration
of non-VXLAN aware devices including servers, rewalls and load-balancers seamless and provide the ability to leverage VXLAN as a
standards based L2 extension technology for non-MPLS environments.
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 aected trac for analysis.
Advanced analytics are provided with features like buer monitoring with congurable thresholds, in-band path and latency
monitoring, event driven trace packets and granular time stamping.
Precision Timing (IEEE 1588)
Arista’s hardware derived Precision Time Protocol solution provides a robust mechanism for accurate in-band time distribution in high
performance environments. The system clock can be synchronized using IEEE 1588 PTP.
Dynamic Load Balancing *
Traditional hash-based load balancing algorithms can result in link and path allocations with short term imbalances and under
utilization of aggregate capacity. This is aggravated further in modern data centers with high trac loads, varied ow duration, mixed
packet sizes and micro-bursts. DLB enhancements to load balancing consider the real time load on links and dynamically assign new
and existing ows to the best link. When imbalances are detected active ows and new ows are allocated to the least loaded paths to
reduce the possibility of drops. Supported with any combination of ECMP and LAG/MLAG, DLB delivers higher throughout with
enhanced load distribution while oering the user an open implementation.
Flexible Pipeline
The Arista 7050X3 series support an enhanced forwarding architecture with smarter and exible packet pipeline which allows the
addition of new capabilities to the data plane of the packet processor through software upgrades without changes or replacement of
the underlying hardware. This allows for rapid testing and deployment avoiding costly replacements or major upgrades. Together with
exible resource allocation provided by the Unied Forwarding Tables (UFT), the programmable pipeline increases the exibility of the
platform allowing for broad use cases and ensures continued investment protection.
Network Address Translation
The Arista 7050X3 series support static and dynamic address translation at line rate and introducing no additional latency when the
mappings are set up. High performance environments can take advantage of NAT to resolve addressing challenges such as masking
internal addresses and translating overlapping ranges resulting in simpler network topologies without performance penalty.
