Description

The Arista 7130LBR is a 1RU composable Layer 1 application switch. It combines an ultra-low-latency layer 1 crosspoint, two Xilinx Virtex UltraScale+ VU9P-3 FPGAs and an integrated R3-series L2/L3 switch chip running Arista EOS. It is aimed at low-latency trading and colocation, market-data fan-out, network monitoring and custom in-network FPGA applications.

This variant provides 48 SFP28 front-panel ports (10/25GbE) and 6 QSFP-DD ports that run as 8x 10G NRZ lanes each, for 96 x 10/25G lanes in total. The layer 1 crosspoint supports 1-25Gbps per lane with latency from 5 ns. Each FPGA has 32GB of DDR4, and the integrated R-Series switch delivers 1.5 Tbps of throughput with a 4 GB packet buffer. It is supplied with front-to-rear airflow, two hot-swap 1+1 redundant AC power supplies and three N+1 redundant hot-swap fans.

It works with 10GBASE SFP+ optics and cables, 1GbE SX/LX/TX, 40G QSFP+ optics and QSFP-DD DAC breakouts. Spare fan trays use part number FAN-7011H. Licensing follows EOS Feature License Group 4, with a minimum EOS of 4.36.0F.

Features

- Composable architecture: any front-panel lane can be linked 1:1 or mirrored to either FPGA or the integrated switch via the layer 1 crosspoint
- Layer 1 functions including signal regeneration, media conversion, port mirroring, telemetry and dynamic patching
- Integrated R3-series switch with wire-speed L2/L3 forwarding, BGP, OSPF and PIM
- LANZ microburst detection, tap aggregation mode and precision time stamping
- FlexRoute engine supports the full internet routing table in hardware
- FPGA Development Kit with example code and IP cores for custom in-network applications
- IEEE 1588v2 PTP and PPS timing via SMA ports with an OCXO clock
- Arista EOS with Linux shell access, streaming telemetry and CloudVision support

FAQs

Q: Which licences does this switch use?
A: It runs Arista EOS and sits in EOS Feature License Group 4, with a minimum EOS of 4.36.0F. Optional licences include LIC-FIX-4-E, LIC-FIX-4-V, LIC-FIX-4-V2, LIC-FIX-4-Z, LIC-FIX-4-FLX-L and LIC-FIX-4-FLX. Arista FPGA applications such as MetaWatch and MetaMux are separate offerings.

Q: What power supplies does it use?
A: It uses two hot-swap AC power supplies in a 1+1 redundant configuration. The model is PWR-1512-AC, rated 1500W with 200-240V AC input and an IEC C13 connector.

Q: What speeds do the QSFP-DD ports support?
A: The 6 QSFP-DD ports run as 8x 10G NRZ lanes only. Breakout cables expose the individual lanes but do not add higher-speed support.

Q: Which optics and cables work with the front-panel ports?
A: Supported options include 10GBASE-SR, LR, ER, ZR, CR, AOC, T and DWDM SFP+, 1GbE SX, LX and TX, and 40G QSFP+ (SR4, LR4, ER4, CR4, AOC). QSFP-DD DAC breakouts to 25G, 50G, 100G, 200G and 400G copper are also supported. Minimum EOS versions for each module are listed on the Arista transceivers and cables page.

Q: What airflow does this variant use?
A: This SKU uses front-to-rear airflow. The fan tray is FAN-7011H, and the three fans are hot-swappable with N+1 redundancy.
