Arista DCS-7130-48LS-F | 7130 48-Port 10G SFP+ FPGA Switch, 5ns Latency

Q: What is the primary use case for the Arista 7130-48LS?
A: The 7130-48LS is designed for ultra-low latency applications requiring programmable packet processing, including high-frequency trading, financial market data distribution, network visibility and monitoring, tap aggregation, and specialized research networks. The integrated FPGA enables custom application development while maintaining deterministic 5-nanosecond Layer 1 switching performance.

Q: Does this switch require a separate power supply?
A: Yes, the DCS-7130-48LS-F requires a PSU/Fan kit sold separately. It supports dual redundant hot-swappable 460W AC power supplies designed for front-to-rear airflow configurations, ensuring high availability in production environments.

Q: What FPGA development tools are supported?
A: Arista provides a comprehensive FPGA Development Kit (FDK) with complete access to the Xilinx UltraScale VU7P-2 FPGA resources. The platform supports Arista's LB (Leaf Breakout) board standard and includes application framework tools for packaging and deploying custom FPGA applications alongside native EOS management.

Q: Can this switch operate as a traditional Layer 2/3 switch?
A: The 7130-48LS primarily operates as a Layer 1+ switch with ultra-low latency crosspoint switching and FPGA processing. While it runs Arista EOS for management and includes an x86 CPU, it is optimized for specialized applications rather than traditional Layer 2/3 forwarding. For standard switching with FPGA capabilities, consider the 7130LBR series which includes integrated Broadcom Jericho2 switching silicon.

Q: What optical transceivers are compatible with the SFP+ ports?
A: The 48 SFP+ ports support industry-standard 100M, 1G, and 10G optical transceivers and direct attach copper (DAC) cables. Arista provides a comprehensive transceiver compatibility matrix on their website. All ports are multi-rate capable and support standard SFP and SFP+ modules including SR, LR, LRM, and BiDi variants.
