With 32 1/10G SFP+ ports, two 100G QSFP100 uplinks and a 3 GB packet buffer, the 7020SR-32C2 handles bursty 10G traffic in storage, media and leaf roles where shallow-buffer switches drop packets. Arista rates it at 1.04 Tbps and 300 Mpps, with latency from 3.8 microseconds.
Two 400W AC power supplies are installed in a 1+1 redundant pair. Arista lists PWR-400AC-BLUE (400W AC) and PWR-400-DC-BLUE (400W DC) as the spares for this front-to-back model. Cooling comes from two hot-swap FAN-7001C-F fan modules.
Airflow is front-to-back (port-side intake). A back-to-front version is also sold, so match all fans and power supplies to the airflow your rack needs. The switch mounts with the KIT-7021 accessory kit.
Management is through a 100/1000 port, an RJ-45 RS-232 console and USB, with 8 GB DRAM and 8 GB flash. The 1RU chassis weighs 14.4 lb and measures 17.3 x 13.6 x 1.71 in. Advanced Layer 3 features such as BGP and OSPF need an Arista Enhanced L3 license, which is not included and is available from Arista partners.
A new DCS-7020SR-32C2-F is also available.
Check your rack depth, power feeds, and cold-aisle orientation before you order, since the airflow direction is set by the fans and power supplies installed.
This seller refurbished DCS-7020SR-32C2-F is tested, working, and covered by the NetworkTigers one-year warranty.
