NEW Arista DCS-7050Q-16-F 16x 40GB QSFP+ 8x 10GB SFP+ Front-to-Back Air Switch

The DCS-7050Q-16-F is a 1RU switch from the original 7050 series with 16 QSFP+ ports at 40GbE and eight 10GbE SFP+ ports. Breakout gives up to 64 10GbE ports. The SFP+ ports share capacity with two QSFP+ ports.

Switching capacity is 1.28 Tbps at 960 Mpps. Arista lists latency of 800 to 850 nanoseconds on the QSFP+ ports and 800 to 1150 nanoseconds on the SFP+ ports, with a 9 MB shared packet buffer. The control plane has 4 GB of DRAM and 2 GB of flash.

This unit is front-to-back (port-side intake). Arista also sells the opposite airflow version (-R), so match it to the rack. Two 460W AC supplies run 1+1 hot-swap, with PWR-460AC-F and PWR-460DC-F as spares, and four hot-swap FAN-7000-F fans run N+1. Use the same airflow on every fan and supply. Typical and maximum draw are 192W and 303W. The switch weighs 18 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-7050Q-16-R with the opposite airflow. A seller refurbished DCS-7050Q-16-F is also available. Matching spares include the PWR-460AC-F power supply and the FAN-7000-F fan module.

This DCS-7050Q-16-F is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
