NEW Arista DCS-7150S-24-R 24x 10GB SFP+ Back-to-Front Airflow Switch

Low latency is the main reason buyers choose the 7150S-24. This 1RU switch has 24 SFP+ ports running at 100M to 10G with 350 nanoseconds of latency, a 9.5 MB shared buffer and IEEE 1588 PTP support for accurate time sync. AgilePorts can combine four 10G ports into one 40G interface.

Arista rates it at 480 Gbps and 360 Mpps. Power draw is 191W typical and 334W maximum. The control plane has 4 GB DRAM and 2 GB flash, managed through a 100/1000 port, an RJ-45 RS-232 console and USB.

Two 460W AC power supplies are installed in a 1+1 redundant pair. Spares are PWR-460AC-R (460W AC) and PWR-460DC-R (460W DC). Four hot-swap FAN-7000-R fans in N+1 move air back-to-front (port-side exhaust). Arista also sells the front-to-back version, so match all fans and supplies to your rack.

The chassis measures 19 x 16 x 1.75 in and weighs 18 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-7150S-24-F with the opposite airflow. A seller refurbished DCS-7150S-24-R is also available. Matching spares include the PWR-460AC-R power supply and the FAN-7000-R fan module.

This DCS-7150S-24-R is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
