Arista DCS-7130LBR-48S6YD-R | 7130LBR 48-Port 10G Switch, 6x QSFP-DD, Dual FPGA

Q: What makes the 7130LBR different from standard switches?
A: The 7130LBR is a composable platform combining a Layer 1 crosspoint, dual large-scale FPGAs, and a high-performance switch chip in a single 1RU device. This allows ultra-low latency FPGA packet processing, flexible port mapping, and eliminates the cable complexity of using separate layer 1, FPGA, and switching devices.

Q: What applications is this switch designed for?
A: The 7130LBR is purpose-built for high-frequency trading, financial market data feeds, telecom timing distribution, media and entertainment streaming, tap aggregation, and any application requiring deterministic low latency with programmable FPGA acceleration and precision timing.

Q: Can I develop custom FPGA applications for this platform?
A: Yes, Arista provides a comprehensive FPGA Development Kit (FDK) with API documentation, sample code, and IP cores. The platform uses the same development standard as other Arista LB-series switches, and developers have complete access to the VU9P-3 FPGA resources.

Q: What is the Layer 1 crosspoint and how is it used?
A: The Layer 1 crosspoint allows any front-panel port to be flexibly routed to the switch chip, FPGAs, or other ports in a 1:1 or mirrored configuration. This enables ports to be configured in-band for switching/routing or out-of-band for FPGA processing and telemetry without re-cabling.

Q: What licensing is required for this switch?
A: The 7130LBR Series supports Arista EOS with flexible licensing options. For advanced routing features including EVPN, VXLAN, and MPLS, the FLX-L license (Group 4) is available. Contact your Arista representative for specific licensing requirements based on your use case.
