Arista 7280R Series

Arista EOS

All Arista products including the 7280R Series runs the same Arista EOS software,
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.

Enhanced Features for High Performance Cloud Networks

The Arista 7280R 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 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.

Advanced 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.

Precise Data Analysis

Arista Latency Analyzer (LANZ) and Precision Data Analyzer (DANZ) are integrated features of EOS. DANZ provides a solution to
monitoring and visibility challenges at 10/40/100Gbps giving IT operations the ability to proactively deliver feedback on congestion
events, filter, replicate, aggregate and capture traffic without affecting production performance. 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
affected traffic for analysis.

Precision Timing (IEEE 1588)

Arista’s hardware derived Precision Time Protocol solution provides a robust mechanism for accurate in-band time distribution in high
performance environments. The system clock can be synchronized using IEEE 1588 PTP.

Virtualization

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation
technologies such as VXLAN. The 7280R 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 7280R 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.

AlgoMatchTM

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 7280RA, 7280R2A and 7280R2K Series of products.

• AlgoMatch enables IPv4 and IPv6 access control at the same scale

• L4 rule ranges are programmed efficiently without expansion or reduced capacity

7280R Accelerated sFlow

SFlow is a powerful tool used commonly by network operators for advanced network telemetry, capacity planning, security analysis and
quality of experience monitoring. All models of the 7280R Series enable sFlow utilizing the high performance CPU. Within modern high
performance systems traffic sampling requires the capability to both sample and process packet rates of hundreds of millions of
packets per second. With the 7280R Series Accelerated sFlow feature the sampling and processing of flow samples into sFlow
datagrams is handled via a dedicated sFlow engine capable of generating up to 1.6Mpps of sFlow data, and of supporting 1:1000
sampling rates of full wire speed systems or higher rates with selective sampling based on triggers and filters. All sFlow v5 information is
included in the sFlow records ensuring consistent integration with existing standard sFlow collection and analysis tools and no loss of
information.

7280R Deterministic Network Performance

The Arista 7280R Series uses a deep buffer virtual output queue (VOQ) architecture that eliminates head-of-line (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 7280 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.
