Overview
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.
