Arista DCS-7130-48LS-R | 7130LS 48-Port 10G SFP+ FPGA Switch, VU7P-2 FPGA

Q: What is the DCS-7130-48LS-R designed for?
A: The DCS-7130-48LS-R is optimized for ultra-low latency network applications such as high-frequency trading, financial market data distribution, and programmable packet processing. It combines Layer 1 switching with FPGA programmability to enable custom network functions with sub-microsecond latency.

Q: Does the DCS-7130-48LS-R include power supplies and fans?
A: No, power supplies and fan modules must be purchased separately. The -R suffix indicates rear-to-front airflow; compatible PSU and fan kits such as PWR-460-AC and FAN-7130-1U-R must be ordered as separate SKUs to complete the system.

Q: What FPGA development options are available?
A: Arista provides FPGA Development Kits (FDK) and Vitis Development Kits (VDK) to enable custom FPGA application creation. The platform offers unrestricted access to the onboard Xilinx VU7P-2 FPGA and supports third-party applications alongside Arista's native MetaMux, MetaWatch, and MetaProtect applications.

Q: What is the difference between the 7130L and 7130LS Series?
A: The 7130LS Series uses a Xilinx UltraScale+ VU7P Speed Grade 2 FPGA, while the 7130L models may vary. Both series share similar port configurations and ultra-low latency capabilities, but the LS variant is specifically tuned for financial trading applications with optimized throughput and latency specifications.

Q: What network applications can this switch run?
A: The switch supports Arista applications including MetaMux (packet multiplexing), MetaWatch (timestamping and monitoring), MetaProtect (filtering), ExchangeApp, and SwitchApp, plus custom-developed FPGA applications. It excels in packet replication, aggregation, filtering, and sub-nanosecond timestamping for market data and network telemetry.
