Arista DCS-7130-48LAS-R | 7130 48-Port Low-Latency Switch, UltraScale VU7P-2 FPGA

Q: What makes the Arista 7130 48LAS different from a standard data centre switch?
A: Unlike conventional Ethernet switches that rely on ASICs and software stacks, the Arista 7130 48LAS uses a Xilinx UltraScale VU7P-2 FPGA to deliver nanosecond-class, deterministic latency. The programmable FPGA fabric enables custom applications — such as market data processing or order routing logic — to run directly in hardware, bypassing CPU and OS overhead entirely.

Q: What is the intended use case for the DCS-7130-48LAS-R?
A: This platform is specifically designed for ultra-low-latency financial applications including high-frequency trading (HFT), algorithmic trading, co-location environments, and market data distribution. It is ideal for trading firms, exchanges, and managed co-location providers requiring deterministic sub-microsecond switching.

Q: What does 'rear-to-front' airflow mean, and why does it matter?
A: Rear-to-front airflow (also called exhaust-front or front-exhaust) means cooling air enters from the rear of the chassis and exits from the front. This matches hot-aisle/cold-aisle data centre configurations where racks face rear-to-rear (hot aisle), ensuring proper thermal management in co-location and enterprise data centre facilities.

Q: Can the FPGA on the 7130 48LAS be programmed with custom logic?
A: Yes. The Xilinx UltraScale VU7P-2 FPGA is a fully programmable device. Arista and third-party developers can deploy custom FPGA bitfiles to implement bespoke trading strategies, market data normalisation, timestamping, and packet filtering logic directly in hardware — enabling capabilities not possible with fixed-function ASICs.

Q: Does the DCS-7130-48LAS-R include redundant power supplies?
A: Yes. The 'R' suffix and '2xAC' designation confirm that this unit ships with dual redundant AC power supplies, providing the power resilience required in mission-critical financial infrastructure and co-location environments.
