7050X4 Series | Features

Virtualization

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

such as VXLAN. The 7050X4 build 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, 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 a ected tra c for analysis.

Advanced analytics are provided with features like bu er monitoring with con gurable thresholds, in-band path and latency

monitoring, event driven trace packets and granular time stamping.

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 tra c 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 o ering the user an open implementation.

Programmable Pipeline

The Arista 7050X4 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, the programmable pipeline increases the exibility of the platform allowing for broad use cases and

ensures continued investment protection.

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.

EOS Licensing

Arista 7050X4 Series with EOS and CloudVision, is designed to provide exibility both in the choice of the appropriate feature

functionality and in the software consumption model. The base feature set of Arista EOS comes bundled with the Arista products and

systems. A set of feature licenses are available to enable additional functionality in advanced feature sets. The traditional licensing

procurement model employs a perpetual term for the right to use the feature, set at a xed price. For Arista CloudVision the

functionality is available as a monthly subscription, for an agreed upon term.

Routing

General Routing functionality (BGP, OSPF, Multicast, etc) is available in the EOS Enhanced (E) license. The EOS Flex-route (FLX) Lite

license expands that to include key features like BGP-EVPN for VXLAN.

Automation/Visibility

CloudVision is the most complete o ering for advanced automation and visibility. Arista also o ers subsets of CloudVision Lite, for

entry-level GUI functionality. CloudVision is o ered as an on-premises appliance (virtual or physical appliance) or as a SaaS-based

software application that is fully managed by Arista. The EOS V2 license includes capability to run custom extensions natively or via

containers in EOS. In addition, the V2 license gives customers an option of integrating with Arista’s best of breed ecosystem for security,

analytics, visibility, and other use-cases.
