Description

The Arista 7132LB-48Y4C is a 1RU programmable, ultra-low-latency Layer 2 and Layer 3 application switch from the 7132LB Series. A Xilinx UltraScale+ VU9P-3 FPGA is wired directly to the front-panel ports, which makes it well suited to exchange trading, high-frequency trading, market data distribution and other latency-critical networks. It also suits high-precision timestamping and latency monitoring, and custom in-network FPGA applications.

The front panel provides 48 SFP28 ports, each configurable for 10G or 25G, and 4 QSFP28 ports that run at 100GE, 4x25GE, 40GE or 4x10GE, for 1.6 (3.2) Tbps FDX of front-panel I/O. Switching latency starts from 89ns with SwitchApp. The FPGA is backed by 4 x 8GB DDR4, and an 8-core x86 CPU with 32 GB DDR4 and a 120 GB SSD handles the control plane. This SKU is the front-to-rear airflow variant with two hot-swap AC power supplies in a 1+1 arrangement and two N+1 hot-swap fans.

It runs Arista EOS 4.30.2 or later and sits in the EOS Group 2 fixed-switch licence category. The SFP28 ports accept 25GE and 10GE optics and cables, while the QSFP28 ports accept 100GE, 4x25GE, 40GE and 4x10GE optics and cables, including Enhanced Performance (E-Series) optics that avoid FEC latency.

FAQs

Q: Which licences does the 7132LB-48Y4C use?
A: It runs Arista EOS 4.30.2 or later and falls in the EOS Group 2 fixed-switch licence category. Optional Group 2 licences include LIC-FIX-2-E (Enhanced L3), LIC-FIX-2-V (Virtualization), LIC-FIX-2-V2 (EOS Extensions, Security, Partner Integration), LIC-FIX-2-Z (Monitoring and Automation) and the FLX routing licences.

Q: What power supplies does this model use and how much power does it draw?
A: This SKU uses two hot-swap PWR-1011-AC supplies in a 1+1 redundant arrangement, each rated at 1000W with 100-200V AC input and an IEC C13 inlet. Typical draw is 367W and maximum is 550W, depending on the FPGA application configuration.

Q: What airflow direction does this SKU have?
A: This SKU is front-to-rear airflow, using FAN-7011M-F fans in an N+1 hot-swap arrangement. Reverse airflow is a separate fan option, FAN-7011M-R.

Q: Which optics and cables work in the SFP28 and QSFP28 ports?
A: The SFP28 ports accept 25GE and 10GE optics and cables such as SFP-25G-SR-E, SFP-25G-LR-E, SFP-25G-SR, SFP-10G-SR, SFP-10G-LR, CAB-S-S-25G and AOC-S-S-25G. The QSFP28 ports accept 100GE, 4x25GE, 40GE and 4x10GE optics and cables such as QSFP-100G-SR4-E, QSFP-100G-LR4, QSFP-100G-CWDM4, QSFP-40G-SR4 and CAB-Q-Q-100G.

Q: What is the FPGA used for?
A: The Xilinx UltraScale+ VU9P-3 FPGA is connected directly to the front-panel ports and runs custom in-network applications, such as market data distribution, low-latency multiplexing and latency monitoring. These can be developed with the Arista FPGA Development Kit or supplied by partners.
