Overview

The Arista 7280R3A Series of fixed systems, including the 7280R3A, 7280R3AM and

the 7280R3AK, are the latest generation of Arista 7000 Series portfolio of data center

switches. The 7280R3A Series are purpose built 100G and 400G systems built for the

highest performance environments, and to meet the needs of the largest scale data

centers and service providers. They deliver scalable L2 and L3 resources, high

bandwidth encryption and high density with advanced features for network

monitoring, precision timing and network virtualization to deliver scalable and

deterministic network performance while simplifying designs and reducing Opex.

Designed for deployment in a wide range of open networking solutions including

large scale layer 2 and layer 3 cloud designs, enterprise data centers and service

provider networks, the 7280R3A Series support 100G and 400G interfaces, up to 54

ports of wirespeed 400G in 2RU. For maximum flexibility, each platform provides a

choice of three levels of scale and functionality with Standard (R3A), Encryption

(R3AM) and Large Scale (R3AK) models available.

The 7280R3A’s capabilities address the requirements for modern networking and

rich multi-media content delivery requiring a lossless forwarding solution in a

compact and energy efficient form factor, offering rich functionality for traditional

data centre, virtualized/overlay networking and wide area networking along with

deep packet buffers, large routing tables and industry leading switching capacity.

7280R3A systems with OSFP or QSFP-DD incorporate a flexible choice of interface

speed including 25G and 50G and support for dense 400G DWDM, providing

unparalleled flexibility and the ability to seamlessly transition data centers to the

next generation of Ethernet performance. The 7280R3A Series provide industry

leading power efficiency. Combined with Arista EOS the 7280R3A Series delivers

advanced features for big data, cloud, virtualized and traditional designs.

Arista EOS

The Arista 7280R3A series run 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.

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 workflows.
