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

With 32 QSFP+ ports at 40GbE and four 10GbE SFP+ ports, the DCS-7050QX-32S-R covers 40GbE spine or leaf duty in 1RU. Breakout cables extend it to as many as 96 10GbE ports, and the four SFP+ ports handle 10GbE links without consuming a QSFP+ port.

The switch delivers 2.56 Tbps and 1440 Mpps with 550 nanoseconds of latency. Its 12 MB shared buffer uses dynamic buffer allocation. The control plane has 4 GB of DRAM, 4 GB of flash, and an optional 120 GB SSD.

Airflow is back-to-front (port-side exhaust). A front-to-back (-F) version also exists, so choose the one that suits the rack. Two 500W AC supplies come installed in 1+1 hot-swap; spares are PWR-500AC-R and PWR-500-DC-R. Four FAN-7000-R fans run N+1 and are hot-swap. Every fan and supply should share one airflow direction. Arista lists typical and maximum draw of 150W and 302W. It is 19 x 16 x 1.75 inches and 20 lb, with a 10/100/1000 management port, RJ-45 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-F with the opposite airflow. A seller refurbished DCS-7050QX-32S-R is also available. Matching spares include the PWR-500AC-R power supply and the FAN-7000-R fan module.

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