NEW Arista DCS-7050CX3-32S-R 32x 100GB QSFP100 2x 10GB SFP+ B-F Air Switch

The DCS-7050CX3-32S-R is a 1RU 7050X3 switch with 32 QSFP100 ports running at 100GbE and two 10GbE SFP+ ports. It delivers 6.4 Tbps (3.2 Tbps each way) and 2 Bpps, with 800 nanoseconds of latency and a 32 MB shared packet buffer.

Airflow is back-to-front (port-side exhaust). Arista also sells a front-to-back (-F) version, so check which way the rack breathes before ordering. Two 500W AC power supplies are included in a 1+1 hot-swap setup; spares are PWR-500AC-R and PWR-500-DC-R. Four hot-swap FAN-7000H-R fans provide N+1 cooling. Do not mix airflow directions between fans and supplies.

Inside, a quad-core x86 CPU with 8 GB of DRAM and 8 GB of flash handles the control plane. For management there is one 10/100/1000 Ethernet port, an RJ-45 RS-232 console, and USB. Typical draw is 168W, with a 343W maximum. It weighs 20 lb and measures 17.3 x 16 x 1.75 inches. This model does not support MACsec.

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-7050CX3-32S-F with the opposite airflow. A seller refurbished DCS-7050CX3-32S-R is also available. Matching spares include the PWR-500AC-R power supply and the FAN-7000H-R fan module.

This DCS-7050CX3-32S-R is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
