Arista DCS-7130-96LAS-R | 7130LS 96-Port SFP+ Layer 1+ FPGA Switch, 5ns, Atomic Clock

Q: What makes the DCS-7130-96LAS-R different from a standard 10GbE data centre switch?
A: Unlike conventional switches that introduce variable buffering and queuing delays, the 7130LS operates as a Layer 1+ FPGA switch with deterministic 5 ns latency and zero buffering. It also integrates a Xilinx Virtex UltraScale+ VU7P-2 FPGA and an Atomic Clock, enabling custom in-line processing and sub-nanosecond timestamping — capabilities not found in standard switching platforms.

Q: What use cases is this switch designed for?
A: The DCS-7130-96LAS-R is purpose-built for ultra-low latency environments including high-frequency trading (HFT), market data distribution, financial exchange co-location, precision timing networks (PTP/GPS replacement), and research or HPC networks where deterministic, jitter-free switching is critical.

Q: Can I develop custom applications for the FPGA on this platform?
A: Yes. Arista provides a comprehensive FPGA Development Kit (FDK) including APIs, IP cores, reference designs, and sample code, allowing network engineers and developers to build bespoke applications targeting the Xilinx VU7P-2 FPGA. The platform also supports a range of Arista-native applications such as MetaWatch, MetaMux, and MetaProtect out of the box.

Q: What is the significance of the integrated Atomic Clock?
A: The built-in Atomic Clock provides an on-board, highly stable frequency reference for sub-nanosecond precise timestamping and synchronisation — removing dependence on external GPS or PTP grandmaster clocks in environments where timing accuracy is critical, such as regulatory trade reporting or precision instrumentation networks.

Q: Is the DCS-7130-96LAS-R compatible with CloudVision?
A: Yes. The 7130LS Series integrates with Arista CloudVision for centralised network orchestration, configuration automation, change management, and real-time streaming telemetry across the entire Arista estate.
