FAQs

Q: What applications is the DCS-7130-48EHS-F designed for?
A: The DCS-7130-48EHS-F is optimized for ultra-low latency financial trading, high-frequency trading (HFT), network acceleration, custom packet processing, real-time analytics, and specialized applications requiring programmable FPGA acceleration. The three on-board UltraScale+ VU9P-3 FPGAs enable development of custom network applications with sub-microsecond latency requirements.

Q: Can I run custom FPGA applications on this platform?
A: Yes, the DCS-7130-48EHS-F fully supports custom FPGA application development using Arista's FPGA Development Kit (FDK). The FDK provides API documentation, IP cores, sample code, and complete unrestricted access to all three on-board FPGAs. Developers can deploy custom applications alongside or instead of Arista's pre-built network applications.

Q: What is the port-to-port latency and how does Layer 1 switching work?
A: The platform delivers 4-5 nanosecond port-to-port latency through its Layer 1 switch fabric. Layer 1 switching operates at the physical layer, enabling direct port-to-port connections, mirroring, and replication without traditional packet processing overhead. This makes it ideal for applications requiring deterministic, ultra-low latency connectivity.

Q: Does this model require separate power supplies and fans?
A: No, the DCS-7130-48EHS-F suffix (-F for front-to-rear airflow) indicates this is a complete unit with 2x redundant 460W AC power supplies and fans included. Models with the # suffix require PSU/Fan kits sold separately, but the -F and -R variants come fully configured.

Q: What management and monitoring capabilities are included?
A: The switch includes an onboard x86 CPU running MOS (Arista's Linux-based OS), providing CLI, web interface, SNMP, per-port Ethernet statistics, real-time telemetry via InfluxData TICK Stack, FPGA application monitoring, and support for standard management protocols. CloudVision integration is available for network-wide orchestration and automation.
