Arista Extensible Operating System (EOS)

The Arista 7050X runs the same Arista EOS software as all Arista products, simplifying network administration. 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. 

With Arista EOS, advanced monitoring and automation capabilities such as zero-touch provisioning, VM Tracer, and Linux-based tools can be run natively on the switch with the powerful x86 CPU subsystem. 

High availability

The Arista 7050X series switches were designed for high availability from both a software and hardware perspective. Key high availability features include:

• 1+1 hot-swappable power supplies and four N+1 hot-swappable fans
• Color-coded PSU's and fans
• Live software patching
• Self-healing software with stateful fault repair (SFR)
• Smart System Upgrade (SSU) and Accelerated Software Update (ASU)
• Up to 64 10GbE or 40GbE ports per link aggregation group (LAG)
• Multi-chassis LAG for active/active L2 multi pathing
• Up to 128-way ECMP routing for load balancing and redundancy

Dynamic buffer allocation

In cut-through mode, the Arista 7050TX switches forward packets with a latency of under 3 usec. Upon congestion, the packets are buffered in shared packet memory that has a total size of 12 MB. Unlike other architectures that have fixed per-port packet memory, the 7050X series use dynamic buffer allocation (DBA) to allocate up to 6.7 MB of packet memory to a single port for lossless forwarding. The 7050TX2-128 has an enhanced 16 MB buffer that is optimized for more demanding environments. 

Scaling data center performance

The Arista 7050X series delivers line rate switching at layer 2 and layer 3 to enable dramatically faster and simpler network designs for data centers that dramatically lowers the network capital and operational expenses. When used in conjunction with the Arista 7000 series of fixed and modular switches it allows networks to scale to over 110,000 10 G servers in a low-latency two-tier network that provides predictable and consistent application performance. The flexibility of the L2 and L3 multi-path design options combined with support for open standards provides maximum flexibility, scalability, and network-wide virtualization. Arista EOS advanced features provide control and visibility with a single point of management. 

Arista Event Management (AEM)

Advanced Event Management (AEM), a sub-system of Arista EOS, is a powerful and flexible tool to automate tasks and customize the behavior of EOS and the operation of the overall data center switching infrastructure. Simplifying the overall operations, AEM provides the tools to customize alerts and ac

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 significant changes to the architecture. The 7050X series includes enhancements that allow for flexible scale-out designs:

• Up to 128-way ECMP and 64-way MLAG provide scalable designs and balance traffic evenly across large scale 2 tier leaf-spine designs
• Custom hash algorithms for efficient 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 10 G/40 G QSFP+ ports
• 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-defined networking

Arista Software Defined 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 Defined Networking that delivers: network virtualization, custom programmability, simplified 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 simplifies 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. 

Smart System Upgrade (SSU)

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 significant 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 flexible 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 7050TX deliver a suite of advanced traffic 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 microburst and congestion events before they impact applications, with the ability to identify the sources and capture affected traffic for analysis. 

Virtualization

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. The 7050X builds 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, the 7050X makes for seamless integration of non-VXLAN aware devices-including servers, firewalls, and load-balancers-and provides the ability to leverage VXLAN as a standards-based L2 extension technology for non-MPLS environments. 

Unified forwarding table (UFT)

Cloud network scalability is directly impacted by the size of switches-forwarding tables. In many systems, a "one size fits all" approach is adopted, using discrete fixed-size tables for each of the common types of forwarding entry. The Arista 7050X leverages a common unified 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 flexibility of the UFT coupled with the range of pre-defined configuration profiles available on the 7050X ensures optimal resource allocation for all network topologies and network virtualization technologies.
