Description

The Arista 7050SX-72Q is a 1RU data centre leaf switch from the 7050X Series, built for 10GbE server access with 40G uplinks. It runs Arista EOS and suits leaf-spine fabrics, high-performance compute and big data environments, as well as networks migrating from 10G to 40G.

This -F variant has 48 SFP+ ports supporting 1/10GbE and 6 QSFP+ 40GbE ports, with front-to-rear airflow and dual hot-swap AC power supplies in a 1+1 arrangement. It delivers 1.44 Tbps of throughput and 1080 Mpps with latency from 550 ns, backed by a 12MB dynamic packet buffer. Typical power draw is 144W with a maximum of 261W. It is a non-PoE switch, and four hot-swap fans provide N+1 cooling.

The SFP+ ports accept 10GBASE-CR, AOC, SR, LR, ER, ZR and DWDM optics, along with 1GbE SX/LX and 100/1000BASE-T modules. The QSFP+ ports accept 40GBASE-CR4, AOC, SR4, LR4 and ER4 optics, and QSFP+ to 4x SFP+ breakout cables are supported. EOS 4.15.4 is the minimum software version.

FAQs

Q: What licensing does this switch use?
A: It runs a single Arista EOS image and belongs to the Arista Group 2 fixed-switch licence group. Optional add-on licences such as LIC-FIX-2-E (Enhanced L3), LIC-FIX-2-V (VMTracer and VXLAN) and LIC-FIX-2-Z (Monitoring and Automation) are sold separately.

Q: What power does it need?
A: It uses dual hot-swap PWR-500AC power supplies rated 100-240VAC, 50/60Hz, with IEC C13 input. Typical draw is 144W and maximum is 261W. It is a non-PoE switch, so it does not power downstream devices.

Q: Which optics and cables work in the SFP+ and QSFP+ ports?
A: The SFP+ ports support 10GBASE-CR (0.5 to 5m), AOC, SR, LR, ER, ZR and DWDM optics, plus 1GbE SX/LX and 100/1000BASE-T modules. The QSFP+ ports support 40GBASE-CR4, AOC, SR4, LR4 and ER4 optics, and QSFP+ to 4x SFP+ breakout cables.

Q: Which airflow direction does the -F model use?
A: The -F suffix denotes front-to-rear airflow. The airflow direction is set by the fan and power supply configuration, so match it to the hot and cold aisle layout of your rack.

Q: What is the minimum EOS version?
A: The minimum supported EOS version is 4.15.4.
