Description
The Arista 7280R Series of fixed 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
efficient 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 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 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 flexible choice of interface speed
including 25GbE and 50GbE providing unparalleled flexibility and the ability to
seamlessly transition data centers to the next generation of Ethernet performance.
The 7280R Series provide industry leading power efficiency 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.
