NEW Arista DCS-7050QX2-32S-F 32x 40GB QSFP+ 4x 10GB SFP+ F-B Airflow Switch

The DCS-7050QX2-32S-F is the second-generation version of the 7050QX-32S. It keeps the same 1RU layout of 32 QSFP+ ports at 40GbE and four 10GbE SFP+ ports, with breakout to as many as 96 10GbE ports, and doubles DRAM to 8 GB.

Throughput is 2.56 Tbps at 1440 Mpps with 550 nanoseconds of latency. The packet buffer grows to 16 MB. Flash is 4 GB, and a 120 GB SSD was offered as an option. Power use is lower than the first version, with Arista listing typical and maximum draw of 129W and 283W.

This unit is front-to-back (port-side intake). Arista also sells the opposite airflow version (-R), so match it to the rack. Two 500W AC supplies run 1+1 hot-swap, with PWR-500AC-F or PWR-500-DC-F as replacements, and four hot-swap FAN-7000-F fans run N+1. Use the same airflow on all fans and supplies. The switch weighs 20 lb and measures 19 x 16 x 1.75 inches.

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-7050QX2-32S-R with the opposite airflow. A seller refurbished DCS-7050QX2-32S-F is also available. Matching spares include the PWR-500AC-F power supply and the FAN-7000-F fan module.

This DCS-7050QX2-32S-F is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
