7280R3A Modular Data Center Switch Router
The Arista 7280R3A Modular Series are purpose built 100G and 400G systems for the highest performance environments, meeting the needs of the largest scale data centers and service providers.
The Arista 7280R3A Modular Series are purpose built 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 modular 7280R3A system provides 14.4 Tbps of packet processing in an extremely compact and power efficient 4RU form factor providing flexibility to deploy a range of interface types. Line rate performance with up to 144 ports of 100G or 36 ports of 400G is combined with rich functionality for 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 and secure data center interconnect applications and provide complete deployment flexibility. All elements of the 7280R3A modular are field replaceable, and optimized for simple maintenance, a broad range of network interfaces with a choice of industry standard interfaces allowing for easy transitions to the latest 100G/400G networks. Combined with Arista EOS the 7280R3A series deliver advanced features for high performance large scale layer 2 and layer 3 cloud designs, enterprise data centers and service provider networks.
