Arista DCS-7130-48EHS-R | 7130 48-Port 10G SFP+ FPGA Switch, 3x VU9P-3, 1RU

Q: What are the primary use cases for the DCS-7130-48EHS-R?
A: This switch is designed for ultra-low latency financial trading applications, high-frequency trading platforms, market data distribution and processing, custom FPGA-based network acceleration, packet capture and timestamping with sub-nanosecond precision, and Layer 1 traffic aggregation and tapping in data centers.

Q: What FPGAs are included and how are they connected?
A: The DCS-7130-48EHS-R includes three Xilinx UltraScale+ VU9P-3 FPGAs. The central FPGA connects to 56 Ethernet transceivers, while each of the two leaf FPGAs connects to 14 transceivers. The FPGAs communicate via parallel bus links with approximately 8ns inter-FPGA latency, and all three connect directly to the Layer 1 switch fabric.

Q: Can I develop custom applications for the FPGAs?
A: Yes, Arista provides the FPGA Development Kit (FDK) with documentation, libraries, APIs, low-latency IP cores, and examples. The platform supports custom FPGA application deployment through MOS CLI or API, with complete access to FPGA facilities. Arista also offers pre-built applications like MetaMux, MetaWatch, and MetaProtect.

Q: What management options are available?
A: The switch runs MOS (Metamako Operating System), a Linux-based OS providing CLI and web interface management, SNMP support with traps for environmental, authentication, link state, memory, and disk monitoring, integrated telemetry via InfluxData TICK Stack, application monitoring for Layer 1 switch statistics, and standard tools like syslog, net-snmp, Bash, and Python.

Q: What power supplies and accessories are required?
A: The DCS-7130-48EHS-R requires PSU and fan kits sold separately. Compatible power supplies include PWR-460AC-F (front-to-rear airflow) or PWR-460AC-R (rear-to-front airflow) 460W AC PSUs, with dual redundant PSU support. The -R suffix indicates configurable fans and PSU options for rear-to-front airflow.
