Overview

The Arista 7280R3 Series of fixed systems, including the 7280R3 and the 7280R3K,

are key components of the Arista 7000 Series portfolio of data center switches. The

Arista 7280R3 Series are purpose built 25G, 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 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. The 7280R3 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.

The 7280R3 can be deployed in a wide range of open networking solutions

including large scale layer 2 and layer 3 cloud designs, overlay networks, virtualized

or traditional enterprise data center networks. Deep packet buffers and large

routing tables allow for internet peering, interconnect and Inter-DC networking. The

broad range of interfaces and density choice provides deployment flexibility.

The 7280R3 Series are available in a range of models with a choice of 400G, 100G

and 25G that offer up to 24 ports of wire speed 400G in a 1RU system.

7280R3 support for 100G QSFP incorporates a flexible choice of interface speed

including 25G and 50G providing unparalleled flexibility and the ability to

seamlessly transition data centers to the next generation of Ethernet performance.

The 7280R3 Series provide industry leading power efficiency with airflow choices

for back to front, or front to back. An optional built-in SSD supports advanced

logging, data captures and other services directly on the switch. Combined with

Arista EOS the 7280R3 Series delivers advanced features for big data, cloud,

virtualized and traditional designs.

Arista 7280R3 Series

Arista EOS

All Arista products including the 7280R3 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.
