Arista DCS-7130LBR-48S6QD-F | 7130LBR 48-Port 10G Switch, 6x QSFP-DD, Dual FPGAs

Q: What makes the Arista 7130LBR suitable for high-frequency trading and financial applications?
A: The 7130LBR features ultra-low-latency Layer 1 switching, dual VU9P-3 FPGAs for programmable packet processing, Precision Time Protocol (PTP IEEE 1588v2) with PPS inputs for nanosecond-level timestamping, and a flexible crosspoint architecture that enables deterministic forwarding critical for trading applications.

Q: How do the QSFP-DD ports work on the 7130LBR?
A: Each of the 6 QSFP-DD ports operates as 8 x 10G NRZ lanes. Using breakout cables, each port can be configured as 2 x 40GbE or 8 x 10GbE interfaces, providing flexibility to scale to a total of 96 x 10G lanes across the platform.

Q: Can I develop custom FPGA applications for this switch?
A: Yes, Arista provides the FPGA Development Kit (FDK) with API documentation, sample code, and IP cores. The dual Xilinx VU9P-3 FPGAs support custom application development and are optimized for Arista's network applications and third-party partner applications.

Q: What is the Layer 1 crosspoint and how is it used?
A: The high-density Layer 1 crosspoint allows any front-panel port to be dynamically linked 1:1 or mirrored to any platform component. Ports can be flexibly configured as in-band for switching/routing or out-of-band for telemetry and tap aggregation, enabling the 7130LBR to replace multiple separate devices.

Q: What licensing and software does the 7130LBR require?
A: The switch runs Arista EOS (minimum 4.30.2F) and supports Group 4 licenses, which include full routing capabilities with up to 2M routes, advanced ACLs, EVPN, VXLAN, Segment Routing, and MPLS. The switch integrates with Arista CloudVision for network-wide automation and telemetry.
