NEW Arista DCS-7050S-64-F 48x 10GB SFP+ 4x 40GB QSFP+ Front-to-Back Air Switch

The DCS-7050S-64-F is a 1RU top-of-rack switch from the original 7050 series. It has 48 SFP+ ports at 1GbE or 10GbE and four 40GbE QSFP+ uplinks. Each QSFP+ port breaks out to four 10GbE links, for up to 64 10GbE ports.

Capacity is 1.28 Tbps at 960 Mpps. Arista lists latency of 800 to 1150 nanoseconds on SFP+ and 950 to 1350 nanoseconds on QSFP+, with a 9 MB shared buffer. Memory is 4 GB of DRAM and 2 GB of flash; a separate variant added a 50 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 460W AC power supplies run 1+1 hot-swap, with PWR-460AC-F and PWR-460DC-F as spares. Cooling is four hot-swap FAN-7000-F fans in N+1. Keep fans and supplies on the same airflow direction. Typical and maximum draw are 125W and 220W. The switch is 19 x 16 x 1.75 inches and weighs 17 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-7050S-64-R with the opposite airflow. A seller refurbished DCS-7050S-64-F is also available. Matching spares include the PWR-460AC-F power supply and the FAN-7000-F fan module.

This DCS-7050S-64-F is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
