Marketing Information:
- The Arista 7280R3 Series of #xed 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 e”cient 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 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 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
- exible choice of interface speed including 25G and 50G providing unparalleled
- exibility and the ability to seamlessly transition data centers to the next generation of Ethernet performance. The 7280R3 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 7280R3 Series delivers advanced features for big data, cloud, virtualized and traditional designs.
