Arista DCS-7130LBR-48S6YD-F | 7130LBR 48-Port 10G Switch, 6x QSFP-DD, 2x FPGA

Q: What is the primary use case for the DCS-7130LBR-48S6YD-F?
A: This switch is designed for ultra-low latency applications such as high-frequency trading, custom FPGA-based network processing, tap aggregation, network monitoring, and visibility solutions. The Layer 1 crosspoint and dual FPGAs enable flexible, programmable data plane processing with sub-100ns latency.

Q: Can the QSFP-DD ports be broken out to multiple 10G connections?
A: Yes, each of the 6 QSFP-DD ports operates as 8x 10G NRZ lanes and can be broken out to 2x 40GbE or 8x 10GbE interfaces using breakout cables, providing up to 96 total 10G lanes across the switch.

Q: What is the Layer 1 crosspoint and how does it work?
A: The Layer 1 crosspoint is a high-density switching fabric that allows any front-panel port to be linked 1:1 or mirrored to any platform component, including the FPGAs, R-series switch chip, or other ports. This enables flexible in-band and out-of-band configurations for switching, routing, tap aggregation, and telemetry offload.

Q: What FPGA development tools are available for this platform?
A: Arista provides the FPGA Development Kit (FDK) which includes API documentation, sample code, and IP cores to streamline custom application development. The platform supports Arista's pre-built network applications as well as third-party and customer-developed FPGA applications.

Q: What does the -F suffix indicate in the model number?
A: The -F suffix indicates front-to-rear airflow, meaning the switch intakes cool air from the front (port side) and exhausts hot air from the rear. This is designed for installations where the front of the switch faces the cool aisle in a data centre rack.
