Description

The Arista 7280R is a 2RU data centre switch router built for large-scale layer 2 and layer 3 cloud designs, overlay networks and virtualised or traditional enterprise data centre networks. Deep packet buffers and large routing tables also make it a fit for internet peering, interconnect and inter-DC networking. It runs Arista EOS.

This 7280CR-48 provides 48 QSFP100 ports and 8 QSFP+ ports, with up to 10.24 Tbps of full-duplex throughput, a 5.76 Bpps forwarding rate and latency from 3.8 us. It carries 32 GB of packet buffer memory, and ports run flexible 10, 25, 40, 50 and 100GbE speeds, up to 192 x 25GbE or 224 x 10GbE using breakout. This SKU is the front-to-rear airflow version with 2 x 1900W AC hot-swap power supplies in a 1+1 redundant arrangement, 4 hot-swap fans and C19-C20 power cords.

The QSFP100 ports accept 100GBASE optics and cables including SR4, LR4, CWDM4, PSM4, AOC and CR4, while the QSFP+ ports accept 40GBASE SR4, LR4, ER4, AOC and CR4 as well as 4x10G breakout. The switch is managed with Arista CloudVision.
