7260X3 Series 10/25/40/50/100G Data Center Switches

The Arista 7260X3 Series are purpose built high performance, high density, fixed configuration, data center switches with wire speed layer 2 and layer 3 features.

Arista 7260X3 Series

Increased adoption of high performance servers coupled with applications using higher bandwidth is accelerating the need for dense 100 Gigabit Ethernet switching in both leaf and spine tiers of modern networks. The Arista 7260X3 Series are purpose built high performance, high density, fixed configuration, data center switches with wire speed layer 2 and layer 3 features, combined with advanced features for software defined cloud networking and emerging requirements. With 64 QSFP100 ports the 7260CX3-64 is a dense 40/100GbE system that can support a flexible combination of up to 64x 40/100GbE, 128x 50GbE or 10/25GbE of wire speed performance in a 2RU system. The Arista 7260CX3-64 combines low latency, and a shared packet buffer pool of 42MB that is allocated dynamically to ports that are congested. Combining 100GbE density and industry leading power efficiency with typical power consumption under 10W per 100GbE port the 7260CX3-64 is ideal for both middle or end of row leaf or collapsed spine tiers with airflow choices for back to front, or front to back. With support for a flexible combination of speeds including 10G, 25G, 40G, 50G and 100G and combined with Arista EOS, the 7260CX3-64 delivers rich features for big data, cloud, virtualized and traditional designs and accommodates the myriad different applications and east-west traffic patterns found in modern data centers.
