FAQs

Q: What topologies does the SN5600D support?
A: The SN5600D is designed for leaf, spine, and super-spine topologies in AI/ML training clusters and hyperscale data centres. It supports both top-of-rack and end-of-row deployment models, making it ideal for NVIDIA Spectrum-X accelerated Ethernet fabrics and standard leaf/spine architectures.

Q: What port speeds and breakout options are supported?
A: Each of the 64 OSFP ports supports flexible speeds from 10GbE to 800GbE, including 10/25/40/50/100/200/400/800GbE configurations. The single SFP28 management port supports 1G/10G/25GbE for out-of-band management.

Q: What is the difference between the SN5600D and SN5600 models?
A: The SN5600D variant is powered by a 48VDC busbar input, making it suitable for telecom and carrier-grade data centre environments that use DC power infrastructure. It also includes MGX mounting hardware, whereas the standard SN5600 uses dual AC power supplies and tool-less rail kits.

Q: Is this switch compatible with NVIDIA Spectrum-X deployments?
A: Yes, the SN5600D is purpose-built for NVIDIA Spectrum-X accelerated AI Ethernet solutions. It integrates seamlessly with NVIDIA BlueField DPUs, ConnectX SmartNICs, and LinkX interconnects to deliver optimised performance for AI/ML workloads with advanced RoCE capabilities.

Q: What operating systems can run on this switch?
A: This specific SKU ships with Cumulus Linux authentication pre-installed. The SN5000 series supports multiple network operating systems including Cumulus Linux, ONIE for bring-your-own-OS flexibility, and is compatible with various open networking stacks for data centre automation.
