Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency. Arista’s 64-bit EOS is purpose built for high performance, large scale workloads and embeds advanced monitoring, telemetry and automation capabilities. With a powerful x86 CPU subsystem and full access to Linux, a wealth of standard tools can also be run natively on the switch for simple integration into automation work/f_lows.

7050X4 Series | Features Dynamic Buffer Allocation In cut-through mode, the Arista 7050X4 switches forward packets with a consistent low latency of 900 nanoseconds. Upon congestion, the packets are buffered in an intelligent fully shared packet memory that has a total size of up to 132MB for superior burst absorption. Unlike other architectures that have /f_ixed per-port packet memory, the 7050X4 Series use dynamic thresholds to allocate packet memory based on traffi c class, queue depth and quality of service policy ensuring a fair allocation to all ports of both lossy and lossless classes. Buffer 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 De/f_ined Networking that delivers: network virtualization, custom programmability, simpli /f_ied 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/f_ies management and provisioning, speeds up service delivery, lowers costs and creates opportunities for competitive differentiation, 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/f_icant changes to the architecture. The Arista 7050X4 include enhancements for /f_lexible scale-out designs:

• 128-way ECMP and 64-way MLAG to provide scalable designs and balance traffi c evenly across large scale 2 tier leaf-spine designs
• Equal and Unequal Cost Multi-Pathing (UCMP) for /f_lexible traffi c balancing in large scale multi-tier topologies
• Custom hash algorithms for effi 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/200G/400G interfaces for multi-speed /f_lexibility
• Support for standards based IEEE 50GbE PAM4 for simple and cost effective migration from 25G and 100G to 50G and 400G
• 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 400G to eliminate down-time when implementing speed changes Flexible Forwarding Table Network scalability is directly impacted by the size of a switches forwarding tables. In many systems a 'one size /f_its all' approach is adopted using discrete /f_ixed size tables for each of the common types of forwarding entry. The Arista 7050X4 leverage /f_lexible forwarding tables for the L2 MAC, L3 Routing, L3 Host and IP Multicast forwarding entries, which can be /f_lexibly allocated per entry type. The ideal size of each partition varies depending on the network deployment scenario. The /f_lexibility of the forwarding table coupled with the range of pre-de /f_ined pro/f_iles available on the 7050X4 ensures optimal resource allocation for all network topologies and network virtualization technologies. AI Analyzer * Traditional software-based tra ffi c counters/uni00A0do not lend themselves to /uni00A0examine AI/ML tra ffi c patterns, which exhibit /uni00A0unique ramp up behavior in very short intervals of time. The AI Analyzer is a hardware capability that enables the collection of ECMP member utilization data, aggregated over extremely short periods of time. This allows the Arista 7050X4 series to e ffectively analyze the tra ffi c patterns, with a time interval as granular as 100 microseconds. The results of such an analysis can then be applied to /f_ine tune dynamic load balancing workloads uniformly across the ECMP member links, which is a key requirement for AI/ML applications. 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 affect large numbers of devices and cause signi /f_icant 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. * Not currently supported in EOS

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. Offering a wire-speed gateway between VXLAN and traditional L2/3 environments, they make integration of non-VXLAN aware devices including servers, /f_irewalls 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 ffected tra ffi c for analysis. Advanced analytics are provided with features like bu ffer monitoring with con /f_igurable 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 ffi c loads, varied /f_low 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 /f_lows to the best link. When imbalances are detected active /f_lows and new /f_lows 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 offering the user an open implementation. Programmable Pipeline The Arista 7050X4 series support an enhanced forwarding architecture with smarter and /f_lexible 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 /f_lexible resource allocation, the programmable pipeline increases the /f_lexibility 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 /f_low 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/f_icant internal development. EOS Licensing Arista 7050X4 Series with EOS and CloudVision, is designed to provide /f_lexibility 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 /f_ixed 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./uni00A0 Automation/Visibility CloudVision is the most complete o ffering for advanced automation and visibility. Arista also o ffers subsets of CloudVision Lite, for entry-level GUI functionality. CloudVision is o ffered 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. * Not currently supported in EOS
