Description

The Arista 7130LBR is a composable Layer 1 application switch in a 1RU chassis, built for ultra-low-latency trading, market data distribution and network visibility. It combines a Layer 1 crosspoint, two Xilinx UltraScale+ VU9P-3 FPGAs and an integrated R3-series Layer 2/3 switch chip, and every front-panel lane can be connected to either FPGA, the switch chip, or any combination of them.

This SKU provides 48 SFP28 ports (10/25G) and 6 QSFP-DD ports operating as 8 x 10G NRZ lanes each. Layer 1 crosspoint latency starts from 5 ns at 1 to 25Gbps per lane, each FPGA has 32GB of DDR4, and the R-Series switch delivers 1.5 Tbps with a 4 GB packet buffer. An 8-core x86 CPU with 64 GB DRAM and a 120 GB SSD runs Arista EOS. It is fitted with two hot-swap AC power supplies in a 1+1 arrangement and three hot-swap fans with rear-to-front airflow.

The 7130LBR runs EOS 4.36.0F or later and uses Group 4 feature licences. QSFP-DD ports support breakout to 2x40GbE or 8x10/25GbE, and the SFP28 ports accept 10GBASE and 1GbE SFP optics, DACs and AOCs.

Features

- Composable architecture: any front-panel port can be linked 1:1 or mirrored to either FPGA or the R-Series switch via the Layer 1 crosspoint
- Layer 1 functions including signal regeneration, media conversion, port mirroring, telemetry, dynamic patching and per-link statistics
- Dual FPGAs supporting two parallel application instances
- FPGA Development Kit (FDK) for custom in-network applications
- Integrated R3-series switch with wire-speed L2/L3, BGP, OSPF, PIM, LANZ microburst detection and tap aggregation
- Precision timing with PTP IEEE 1588v2, SyncE and PPS SMA ports
- Arista EOS with Linux shell access and CloudVision support
- MACsec, MPLS/Segment Routing and EVPN support

FAQs

Q: What licensing does the 7130LBR use?
A: It runs Arista EOS with Group 4 fixed-switch feature licences, minimum EOS 4.36.0F. Optional tiers 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 products.

Q: What power supplies does this model use?
A: This SKU uses two AC power supplies in a 1+1 hot-swap configuration. The 48S6YD platform takes PWR-1512-AC (1500W, 200-240V AC) or PWR-1511-DC (1500W, -48 to -60 VDC), and the rear-to-front airflow fan tray is FAN-7011H.

Q: How do the QSFP-DD ports operate?
A: The QSFP-DD ports run as 8 x 10G NRZ lanes only. They support breakout to 2x40GbE or 8x10/25GbE, and accept QSFP+ 40G optics and DACs/AOCs.

Q: Which optics do the SFP28 ports support?
A: The ports support 10GBASE-SR, SRL, LR, LRL, ER, ZR, CR, AOC, DWDM and T, plus 1GbE SX, LX and TX. Check the Arista transceiver and cable matrix for the minimum EOS version of each module.

Q: How does this SKU differ from other 7130LBR variants?
A: This SKU has 48 SFP28 ports, rear-to-front airflow and dual AC power supplies, which separates it from variants with different port counts, airflow directions or DC power.
