Description

The Arista 7150S is an ultra low latency 1RU Layer 2/3/4 wire-speed switch built for financial trading networks, HPC clusters, cloud data centres and precision-timing (PTP) deployments. This model pairs 48 x 1/10GbE SFP+ ports with 4 x QSFP+ ports, a high precision OCXO clock for IEEE 1588 PTP, front-to-rear airflow and dual hot-swap AC power supplies.

Switching throughput reaches 1.28 Tbps at up to 960 Mpps, with latency from 380 ns on the SFP+ ports. Packet buffer memory is 9.5 MB with dynamic allocation to help absorb microbursts. The 4 x QSFP+ ports run at 10/40GbE, and AgilePorts lets groups of SFP+ ports be configured for 40G, giving up to 16 x 40GbE or 64 x 10GbE ports in total. The two AC supplies run 1+1 redundant and the four fans are N+1 redundant.

The switch runs Arista EOS and sits in Group 2 for EOS feature licences. Optional add-on licences cover Enhanced L3 routing, Monitoring and Automation, EOS Extensions and FLX-Lite. SFP+ ports accept 1G SX/LX and 10G SR, LR, ER, ZR, DWDM, DAC and AOC. QSFP+ ports accept 40G CR4, AOC, SR4, LR4, ER4 and QSFP+ to 4 x SFP+ breakout cables.

A: It runs Arista EOS and is in Group 2 for EOS feature licences. Optional add-ons include LIC-FIX-2-E for Enhanced L3 routing, LIC-FIX-2-Z for Monitoring and Automation, LIC-FIX-2-V2 for EOS Extensions and LIC-FIX-2-FLX-L for FLX-Lite.

Q: What power does the switch use?
A: It has two hot-swap AC power supplies in a 1+1 redundant arrangement, accepting 100-240 VAC through IEC C13 connectors. Typical draw is 224 W and maximum draw is 455 W.

Q: Which optics and cables work in the SFP+ and QSFP+ ports?
A: SFP+ ports support 1G SX/LX, 10G SR, LR, ER, ZR and DWDM, plus 10G DAC up to 5m and AOC up to 30m. QSFP+ ports support 40G CR4, AOC, SR4, LR4 and ER4, as well as QSFP+ to 4 x SFP+ breakout cables.

Q: What airflow direction does this SKU have?
A: This SKU is front-to-rear airflow. The matching spare power supply is PWR-460AC-F and the matching spare fan is FAN-7000-F.

Q: Does it support precision timing?
A: Yes. It includes an integrated high precision OCXO clock and supports IEEE 1588 PTP in both Boundary Clock and Transparent Clock modes.
