Arista Extensible Operating System (EOS)

The Arista 7020R series 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, LANZ, VM Tracer and Linux®-based tools can be run natively on the switch with the powerful x86 CPU subsystem.

High availability

The Arista 7020R switches were designed for continuous operations with system-wide monitoring of both hardware and software components, simple serviceability, and provisioning to prevent single points of failure. Key high availability features include:

• 1+1 hot-swappable power supplies and four hot-swap fans provide dynamic temperature control combined with N+1 redundancy
• Color-coded PSUs and fans that deliver platinum-level power efficiency
• Live software patching
• Self-healing software with SFR
• Up to 32 ports per link aggregation group (LAG)
• Multi-chassis LAG for active-active L2 multi-pathing
• 128-way ECMP routing for load balancing and redundancy

Scaling data center performance

The Arista 7020R series delivers line rate switching at layer 2 and layer 3 to enable dramatically faster and simpler network designs for data centers that lower 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 80,000 1G servers in a high-performance and 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 single point of management.

Software-defined cloud networks

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 CAPEX. 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. 

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 significant changes to the architecture. The Arista 7020R series include enhancements that allow for flexible scale-out designs:

• 6 ports of 1/10 G to provide scalable designs and balance traffic evenly across large-scale two-tier leaf-and-spine designs
• Comprehensive L2 and L3 forwarding table resources for more design choice
• VXLAN gateway, bridging and routing with VM Tracer features to enable next-generation data center designs*
• Virtual output queue (VOQ) architecture and eep packet buffering to eliminate head-of-line (HOL) blocking with low latency
• Wide choice of both 1 G and 10 G transceivers and cables for single port multi-speed flexibility
• Integrated packet capture, sFlow, and multi-port mirroring provide network-wide visibility and monitoring to detect traffic bursts, monitor latency and congestion, and allow capacity planning to improve application performance and availability*

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. 

CloudVision

CloudVision is a network-wide approach for workload orchestration and workflow 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 significant internal development. 

Next-generation provisioning and monitoring

Zero touch provisioning (ZTP) combined with other Arista features, such as VM Tracer's adaptive VLAN configuration, allows data center managers to fully automate the bring-up of network elements and virtual servers, and leverage Arista's unique "hands-off" provisioning. Designed to integrate with VMware®, OpenStack, and Microsoft® OMI, Arista's open architecture allows for integration with any virtualization and orchestration system providing visibility to the VM level, enabling portable policies, persistent monitoring, and rapid troubleshooting of cloud networks. 

7020R deterministic network performance

The Arista 7020R series uses a deep buffer VOQ architecture that eliminates HOL blocking and virtually eliminates packet drops even in the most congested network scenarios. An advanced traffic scheduler fairly allocates bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, fixed priority, or hybrid schemes. As a result, the Arista 7020R can handle the most demanding data center requirements with ease, including mixed traffic loads of real-time, multicast, and storage traffic while still delivering low latency. 

Virtualization*

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. The 7020R 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 7020R makes integration of non-VXLAN aware devices including servers, firewalls and load-balancers seamless and provides the ability to leverage VXLAN as a standards-based L2 extension technology for non-MPLS environments. 

EOS software licensed features

Arista EOS delivers a comprehensive feature set along with single-image consistency with all other Arista switches. The default EOS software has a broad layer 2 feature set with extensive monitoring and provisioning, security, QoS, and management features.  

AlgoMatch

AlgoMatch is a unique Arista innovation for modern cloud networks, combining both software and hardware to enable more flexible and scalable solutions for access control, policy based forwarding and network telemetry. By combining general purpose memory with advanced software algorithms AlgoMatch delivers higher scale, performance and efficiency with lower power and is more cost effective than traditional solutions. AlgoMatch provides a more efficient packet matching algorithm that in turn enables flow matching for access control, policy and visibility. The net benefits are a high performance policy engine with both increased functionality and scale in a cost and power efficient solution. AlgoMatch is available on the 7020RA Series of products.
