Arista DCS-7130-48LAS-F | 7130LS 48-Port 10G SFP+ Layer 1+ FPGA Switch, Atomic Clock

Q: What makes the Arista DCS-7130-48LAS-F different from a standard data centre switch?
A: Unlike traditional store-and-forward or cut-through switches, the 7130LS Series operates as a Layer 1+ FPGA switch, forwarding traffic at the physical layer with deterministic 5-nanosecond port-to-port latency and zero buffering or queuing. The onboard Xilinx UltraScale+ VU7P-2 FPGA also enables programmable in-network applications — functionality not available in conventional switching silicon.

Q: What is the Atomic Clock used for in this switch?
A: The integrated Atomic Clock provides sub-nanosecond precision timing, enabling highly accurate hardware timestamping of network traffic. This is critical for applications such as financial trading analytics, regulatory compliance reporting (e.g. MiFID II), and any environment requiring ultra-precise time synchronisation across distributed infrastructure.

Q: Which Arista applications are supported on the DCS-7130-48LAS-F?
A: The switch natively supports a range of Arista network applications including MetaMux (ultra-low latency multiplexing from 39ns), MetaWatch (precision timestamping and packet analytics), SwitchApp, dynamic patching, one-to-many replication, media conversion, and packet statistics collection. Custom and third-party FPGA applications can also be developed using the Arista FPGA Development Kit (FDK).

Q: Can I deploy custom FPGA logic on this platform?
A: Yes. Arista provides the FPGA Development Kit (FDK), which gives developers access to the VU7P-2 FPGA fabric for custom application development. This allows organisations to implement proprietary in-network processing logic — such as custom order routing algorithms or bespoke timestamping — directly on the switch hardware.

Q: Is the DCS-7130-48LAS-F managed through Arista CloudVision?
A: Yes. The switch runs Arista EOS and integrates with Arista CloudVision, providing centralised workload orchestration, workflow automation, and real-time streaming telemetry. This enables consistent management alongside other Arista EOS-based infrastructure in your environment.

Q: Can I purchase the Arista DCS-7130-48LAS-F in Australia, and what support is available?
