Arista DCS-7130-48LBS-R | 7130L 48-Port 10G SFP+ FPGA Switch, VU9P-3

Q: What is the primary use case for the DCS-7130-48LBS-R?
A: This switch is designed for ultra-low latency applications including high-frequency trading, financial market data distribution, network tap aggregation, and custom FPGA-based application hosting. The 5ns Layer 1+ switching latency and programmable VU9P-3 FPGA make it ideal for performance-critical environments requiring deterministic forwarding and custom packet processing.

Q: Can I develop custom applications for the onboard FPGA?
A: Yes, Arista provides the FPGA Development Kit (FDK) and Vitis Development Kit (VDK) with complete access to the UltraScale VU9P-3 FPGA. The platform supports custom applications alongside Arista's native applications like MetaMux, MetaWatch, and MultiAccess. The integrated x86 server simplifies FPGA application deployment through standard Linux packaging.

Q: What management options are available?
A: The switch runs Arista EOS on an integrated x8664 processor, providing industry-standard CLI, web interface, JSON RPC API, SNMP, and CloudVision network-wide management. It includes full diagnostics capabilities including packet statistics, eye diagram monitoring, tcpdump on every port, and comprehensive SFP+ interface monitoring.

Q: Does this model include power supplies and fans?
A: Yes, the DCS-7130-48LBS-R includes 2 x 460W AC power supplies and fan modules with rear-to-front airflow. Both power supplies and fans are hot-swappable for high availability. The typical power consumption is 190W.

Q: What Layer 1+ features are supported?
A: The switch provides dynamic patching, port mirroring with 1:N replication, ad-hoc tapping, media conversion between 100M/1G/10G speeds, signal regeneration, full SFP+ diagnostics, packet statistics on every port, and precise timestamping capabilities—all with deterministic 5ns latency equivalent to one metre of fibre.
