NEW Arista DCS-7050QX-32S-F 32x 40GB QSFP+ 4x 10GB SFP+ Front-to-Back Air Switch

The DCS-7050QX-32S-F is a 1RU 7050X switch with 32 QSFP+ ports at 40GbE and four 10GbE SFP+ ports. Using breakout cables, it reaches up to 96 10GbE ports. The SFP+ ports handle 10GbE links without using a QSFP+ port.

Arista rates it at 2.56 Tbps and 1440 Mpps with 550 nanoseconds of latency. A 12 MB shared buffer uses dynamic buffer allocation. Memory is 4 GB of DRAM and 4 GB of flash, with an optional 120 GB SSD.

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 power supplies run 1+1 hot-swap, with PWR-500AC-F and PWR-500-DC-F as spares. Four hot-swap FAN-7000-F fans provide N+1 cooling. Keep fans and supplies on one airflow direction. Typical and maximum draw are 150W and 302W. The switch weighs 20 lb and measures 19 x 16 x 1.75 inches. Management ports are 10/100/1000 Ethernet, RJ-45 RS-232 console, and USB.

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

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