Description

The Arista 7132LB is an FPGA-based Layer 2/3 application switch in a 1RU chassis, built around a Xilinx UltraScale+ VU9P-3 FPGA. It is designed for electronic and high-frequency trading, exchange and market-data networks, and regulatory timestamping such as MiFID II RTS 25. It also suits packet filtering, multiplexing and aggregation, and hosting custom or third-party FPGA applications.

The front panel provides 48 SFP28 ports, each configurable for 10G or 25G, plus 4 QSFP28 ports supporting 100GE, 4x25GE, 40GE and 4x10GE. Front panel I/O is 1.6 (3.2) Tbps FDX, and SwitchApp delivers cut-through switching latency from 89ns, with 133ns for L2 and 150ns for L3 at 25G. An 8-core x86 CPU with 32 GB DDR4 and a 120 GB SSD runs Arista EOS. This SKU has rear-to-front airflow and two hot-swap AC power supplies in a 1+1 arrangement, with N+1 fans.

The switch is in EOS Feature License Group 2 and requires EOS 4.30.2 or later. SFP28 and QSFP28 ports accept Arista optics and cables, including the E-Series low-latency parts QSFP-100G-SR4-E, SFP-25G-SR-E and SFP-25G-LR-E.

FAQs

Q: Which licensing does this switch use?
A: It runs Arista EOS and sits in EOS Feature License Group 2, with a minimum of EOS 4.30.2. Optional licences include LIC-FIX-2-E for Enhanced L3 and LIC-FIX-2-Z for Monitoring and Automation.

Q: What power supplies does the -R variant use?
A: It uses two hot-swap 1000W AC power supplies (PWR-1011-AC, 100-200V AC, IEC C13) in a 1+1 redundant arrangement. Typical draw is 367 W and maximum is 550 W, depending on the FPGA application.

Q: Which optics does it work with?
A: SFP28 ports take 25GE and 10GE optics and cables. QSFP28 ports take 100GE, 4x25GE, 40GE and 4x10GE. Arista E-Series low-latency optics such as QSFP-100G-SR4-E, SFP-25G-SR-E and SFP-25G-LR-E run without FEC.

Q: How does this SKU differ from other 7132LB variants?
A: The -R suffix indicates rear-to-front airflow with two AC power supplies. Other variants differ in airflow direction or power supply type, such as the DC option PWR-1011-DC.

Q: Can I run my own FPGA applications on it?
A: Yes. The Arista FPGA Development Kit (FDK) supports custom in-network applications on the VU9P-3 FPGA. Arista applications such as SwitchApp, MetaWatch, MetaMux and MultiAccess are also supported.
