Description

The Arista 7020R Series DCS-7020SR-32C2-F is a 1RU deep-buffer data centre switch running Arista EOS with L2/L3 switching. It suits lossless 10Gb or 1Gb leaf roles in universal cloud networks, big data and HPC, media and entertainment post-processing, edge computing and high-performance IP storage fabrics.

It provides 32 x 1/10GbE SFP+ ports and 2 x 100GbE QSFP100 uplinks, which run at wire-speed 100G or break out to 10G, 25G or 40G modes. Forwarding is up to 1.04 Tbps and 300 Mpps, with latency as low as 3.8 usec and a 3GB dynamic deep packet buffer. The Virtual Output Queue architecture avoids head-of-line blocking and absorbs bursts. This SKU uses front-to-rear airflow with AC power supplies, and it is a non-PoE switch.

The SFP+ ports take 1GbE and 10GbE optics and DACs. Supported power supplies are PWR-400AC and PWR-400-DC, in a 1+1 hot-swap arrangement with N+1 redundant fans.

Enquire with XS Network Tech for new or used pricing and availability.
