In Windows driver doc, it mention “All servers are guaranteed to support 16 VFs” and “OS limits the maximum number of VFs to 32 per Network Adapter”

What’s the difference between 16 and 32?

In Linux driver doc, it mention "NVIDIA adapters are capable of exposing up to 127 virtual instances (Virtual Functions (VFs) for each port in the NVIDIA ConnectX® family cards. "

Why maximum number of CX-7 VFs is different between Windows and Linux?

Hi Xiaodong,
16 is the minimum number of all server Bios can support.
32 is the maximum number of windows can support
32 and 127 is because the difference of Windows and Linux, not HW

Thanks,
Suo
