Arista DCS-7130-96LS-R | 7130 96-Port 10G SFP+ FPGA Switch, 2RU, Rear Airflow

Q: What is the primary use case for the DCS-7130-96LS-R?
A: The DCS-7130-96LS-R is designed for ultra-low latency applications including high-frequency trading, network tap aggregation, real-time data processing, and custom FPGA-based network functions. Its 5 nanosecond Layer 1 switching latency makes it ideal for latency-sensitive financial market data distribution and exchange connectivity.

Q: Does this switch include power supplies and fan modules?
A: No, the DCS-7130-96LS-R requires a separate PSU/Fan kit sold separately. Compatible models include the PWR-460-AC, PWR-500-AC, or PWR-747-AC power supplies depending on power requirements and region.

Q: Can I develop custom FPGA applications on this platform?
A: Yes, Arista provides complete FPGA development toolkits including the FDK (FPGA Development Kit) and VDK (Vitis Development Kit) with unrestricted access to the onboard Xilinx VU7P-2 FPGA. Developers can create custom network processing applications or use Arista's pre-built applications like MetaMux, MetaWatch, and MultiAccess.

Q: What software does the switch run?
A: The 7130-96LS-R runs Arista's MOS (Management Operating System), a Linux-based platform with CLI, web interface, and API support. MOS provides comprehensive management capabilities including SNMP, telemetry, environmental monitoring, and FPGA image deployment while allowing integration with CloudVision network management.

Q: What is the difference between the -R and -F models?
A: The -R suffix indicates rear-to-front airflow (cold aisle intake from rear, hot exhaust to front), while -F models feature front-to-rear airflow. The airflow direction must match your data center's cooling architecture for optimal thermal management.
