Arista DCS-7170-64C-R 7170 Series 64x 100GB QSFP28 Back-to-Front Airflow Switch

The 7170-64C is a 2RU P4-programmable switch with 64 QSFP100 ports and two SFP+ ports, for operators who want to define custom packet processing at 100G scale. The SFP+ ports can also serve management networks or out-of-band monitoring.

Arista rates it at 12.8 Tbps and up to 4.8 Bpps, with latency from 800 nanoseconds and a 22 MB packet buffer. The control plane runs a multi-core x86 CPU with 16 GB RAM, expandable to 64 GB, and 30 GB flash. Power draw is 271W typical and 571W maximum.

Two 745W AC power supplies are installed in a 1+1 redundant, hot-swap pair, with PWR-745AC-R as the AC spare and PWR-1900-DC-R for DC. Four hot-swap FAN-7002-R fans in N+1 move air back-to-front (port-side exhaust). A front-to-back version is also sold, so match fans and supplies to your rack.

Management uses a 10/100/1000 RJ-45 port, an RJ-45 RS-232 console and USB. The chassis measures 19 x 18 x 3.5 in and weighs 34 lb. 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.

Arista also sells the DCS-7170-64C-F with the opposite airflow. A new DCS-7170-64C-R is also available. Matching spares include the PWR-745AC-R power supply and the FAN-7002-R fan module.

This seller refurbished DCS-7170-64C-R is tested, working, and covered by the NetworkTigers one-year warranty.
