Forty-eight 1/10GbE SFP+ ports and four 40GbE QSFP+ uplinks give the DCS-7050S-64-R a classic top-of-rack layout in 1RU. It belongs to the original 7050 series. Breaking out the QSFP+ ports to 4x 10GbE yields as many as 64 10GbE ports.
The switch moves 1.28 Tbps at 960 Mpps. Latency is 800 to 1150 nanoseconds on the SFP+ ports and 950 to 1350 nanoseconds on QSFP+, with a 9 MB shared buffer. It carries 4 GB of DRAM and 2 GB of flash, and a 50 GB SSD was offered on a separate variant.
Airflow is back-to-front (port-side exhaust). Arista also sells a front-to-back (-F) version, so pick the one the rack needs. Two 460W AC supplies come installed, 1+1 hot-swap, and the spares are PWR-460AC-R and PWR-460DC-R. Four FAN-7000-R fans run N+1, hot-swappable. Every fan and supply should share one airflow direction. Arista lists typical and maximum draw of 125W and 220W. It weighs 17 lb at 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-7050S-64-F with the opposite airflow. A seller refurbished DCS-7050S-64-R is also available. Matching spares include the PWR-460AC-R power supply and the FAN-7000-R fan module.
This DCS-7050S-64-R is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
