The 7170-32CD is a 1RU P4-programmable switch with 32 QSFP100 ports and two SFP+ ports. It has half the system pipeline capacity of the 7170-32C, which suits programmable designs that do not need the full pipeline.
The SFP+ ports can also serve management networks or out-of-band monitoring. Arista rates the switch at 6.4 Tbps and up to 2.4 Bpps, with latency from 800 nanoseconds and a 20 MB packet buffer.
Two 747W AC power supplies are installed in a 1+1 redundant, hot-swap pair. Supported supplies are PWR-747AC-RED, PWR-747AC-BLUE and PWR-1900-DC-F or -R for DC. Four hot-swap FAN-7000H-R fans in N+1 move air back-to-front (port-side exhaust). Arista also sells the front-to-back version, so match every fan and supply to that airflow.
The control plane runs a multi-core x86 CPU with 16 GB RAM, expandable to 32 GB, and 30 GB flash. Power draw is 221W typical and 490W maximum, and the switch weighs 22 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-7170-32CD-F with the opposite airflow. A new DCS-7170-32CD-R is also available. Matching spares include the FAN-7000H-R fan module.
This seller refurbished DCS-7170-32CD-R is tested, working, and covered by the NetworkTigers one-year warranty.
