Description

The Arista 7280R3 Series of flxed 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 o!er 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 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 7280R3 Series delivers advanced features for big data, cloud,
virtualized and traditional designs.
