Overview

The Arista 7280R Series of xed systems, including the 7280R, 7280RA, 7280R2,

7280R2A and the 7280R2K, are key components of the Arista 7000 Series portfolio

of data center switches. The Arista 7280R Series are purpose built 10/25/40/100GbE

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 7280R

capabilities address the requirements for modern networking and rich multi-media

content delivery requiring a lossless forwarding solution in a compact and energy

e cient form factor.

The 7280R 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 bu ers and large

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

broad range of interfaces and density choice provides deployment exibility.

The 7280R Series are available in a range of models with a choice of 10GBASE-T,

10GbE and 25GbE SFP with 40GbE and 100GbE QSFP uplinks and systems that o er

up to 60 ports of wire speed 100GbE in a 2RU system.

7280R support for 100GbE QSFP incorporates a exible choice of interface speed

including 25GbE and 50GbE providing unparalleled exibility and the ability to

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

The 7280R Series provide industry leading power e ciency with air ow 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 7280R Series delivers advanced features for big data, cloud, virtualized and

traditional designs.

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.
