Arista 7800R Series Modular Data Center Switches
The Arista 7800R3 Series of purpose built modular switches deliver the industry's highest performance scaling to 460 Tbps of system throughput to meet the needs of the largest scale data centers.
The Arista 7800R3 Series of purpose built modular switches deliver the industry's highest performance scaling to 460 Tbps of system throughput to meet the needs of the largest scale data centers. They combine 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 7800R3 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 and secure data center interconnect applications and provides complete deployment flexibility. Available in a modular system design, as a choice of 16, 12, 8 and 4 slots, the Arista 7800R3 is the next generation of the 7500 Series and delivers a consistent architecture offering the same deep buffer, non-blocking VOQ capabilities while setting a new standard for performance, density, reliability, and power efficiency. The 7800R3 can support up to 576 ports of wire speed 400G and 768 ports of 100G and offers over 460 Tbps of total capacity with a broad choice of line cards. Standards based OSFP and QSFP-DD 400G and QSFP 100G interfaces support a choice of speeds including 50G and 200G providing unparalleled flexibility and the ability to seamlessly transition to next generation Ethernet performance.
