The NVM Express driver is for solid state drives directly

connected to the PCI or PCI Express bus. If you know you

don't have one of these, it is safe to answer N.

This option controls support for multipath access to NVMe

subsystems. If this option is enabled support for NVMe multipath
|

access is included in the kernel. If this option is disabled support

for NVMe multipath access is excluded from the kernel. When this

option is disabled each controller/namespace receives its

own /dev/nvmeXnY device entry and NVMe multipath access is

not supported.
