Arista EOS

All Arista products, including the 7160 Series, run the same Arista EOS software, a single binary image simplifying network administration with a single standard across all switches. 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, together with stateful switchover without the loss of data plane forwarding.

Arista EOS enables advanced monitoring and automation capabilities such as Zero Touch Provisioning, LANZ, VM Tracer, and Linux-based tools to be run natively on the switch.

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 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. It is 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.

The Four Pillars of Arista's Software Defined Cloud Networking:

Universal Cloud Network

• Scalable standards-based MLAG at Layer 2, ECMP for Layer 3, and VXLAN for network virtualization flexibility
• Non-blocking leaf-spine for 10K-100K hosts

Cloud Control

• Standards-based EOS with AEM, ZTP/ZTR, LANZ, and DANZ
• Automated Monitoring for visibility and telemetry

Network Wide Virtualization

• Multi-vendor API Support with eAPI
• Support for VMWare and NSX with VXLAN and VMTracer
• Support for Microsoft OMI and Openstack OVSDB

Network Applications and Automated Management

• Single point of network-wide state with Arista CloudVision
• Networked applications for workload mobility, smart systems rollback and upgrades, and workflow telemetry
• Open Partner integration

Scaling Data Center Performance

The Arista 7160 Series deliver switching capacity that enables dramatically faster and simpler network designs for data centers and lowers both capital and operational expenses. The Arista 7000 Series of fixed and modular systems with a single consistent EOS allows for flexible selections at all tiers of the network and deployment scenarios, including layer 2 MLAG, layer 3 ECMP, VXLAN Overlay, and Internet route scale.

Arista's Multi-Chassis Link Aggregation (MLAG) technology supports a leaf and spine active/active L2 network topology. An Equal Cost Multi-Path (ECMP) design at Layer 3 scales the network in a fully non-blocking, low-latency, two-stage 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 that scales to hundreds of thousands of hosts in a single two-tier design. Both designs support overlay networks via VXLAN and can integrate with standards-based overlay controller solutions.

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 enables IPv4 and IPv6 access control at the same scale.
• L4 rule ranges are programmed efficiently without expansion or reduced capacity.
• Multiple actions can be performed on a single packet or flow.
• User-defined filters allow flexible packet classification based on offsets for custom actions.
• Supports rich policy with consistent semantics that would exhaust classical resources.

Enhanced Features for High Performance Cloud Networks

The Arista 7160 delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high-performance environments, with solutions for automation, data monitoring, precise timing, and next-generation virtualization.

Automating the data center enables customers to dynamically provision computing resources in the most efficient manner while also meeting business needs by maintaining service level agreements (SLAs). Arista EOS automates complex IT workflows and simplifies network operations while reducing or even eliminating downtime. Arista EOS's 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.

Arista offers solutions for a variety of approaches to cloud-like network automation, addressing the needs of the largest public cloud environments as well as applying those lessons learned in the turnkey CloudVision automation offering.

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 needing any significant internal development.

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 actions. 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.

Flexible Profiles

Network scalability is directly impacted by a switch's forwarding tables. The 7160 Series provide flexibility on how memory resources are allocated among the different tables and features. A Forwarding Profile is a pre-defined allocation of the forwarding table resources to assign specific table sizes. Forwarding profiles allow the available resources to be optimally allocated for specific features or a set of features for a given use case. This allows for deployment of the 7160 Series across multiple use cases, each configured with a different forwarding profile to suit the unique requirements.

Programmable Pipeline

The 7160 programmable packet pipeline allows the addition of new protocols, encapsulation, and tunneling features to the packet processor through simple software upgrades without changes to the underlying hardware. This allows for rapid testing and deployment, avoiding costly replacements or major upgrades. A recent example of a new encapsulation in the data center environment is VXLAN, which required new silicon technology, delaying customer deployments and innovation.

Virtualization

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. The 7160 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 7160 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.

Maximum Network Design Flexibility

• Scalable designs with up to a 128-way ECMP provide flexibility and balance traffic evenly across the largest leaf-spine designs.
• MLAG designs are effective at almost any layer of the network and maximize cross-sectional bandwidth with fast failover times measured in 100s of milliseconds for link failures.
• VXLAN gateway, bridging, and routing with VMTracer features enable next-generation data center designs.
• Wide choice of interfaces with broad support for flexible 10GbE, 25GbE, or 50GbE modes.
• Support for standards-based IEEE 25GbE with mix-and-match support for both 10G and 25G for simple and cost-effective migration.
• AlgoMatch to match business intent to network policy for flow matching, access control, and telemetry.
• Flexible forwarding profiles for optimal allocation of L2 and L3 forwarding table resources in multiple use cases.
• EOS tools for network-wide visibility and monitoring to detect traffic bursts, monitor latency and congestion, and allow capacity planning to improve application performance and availability.

Arista 7160 Flexible Combinations

The Arista 7160 lowers total cost of ownership as they are designed to be efficient with power per port as low as 10W per 100GbE port, which combined with front-to-rear cooling to optimize the data center environment, produces the most reliable, dense, and power-efficient 100GbE fixed-configuration switch.

7160 Advanced Traffic Manager and Fully Shared Buffer

The 7160 Series each incorporate an advanced traffic manager with 24MB of packet buffer that is fully shared across all ports.
