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.
|
|
|

To compile this driver as a module, choose M here: the
|
|
module will be called nvme.

This option enables support for multipath access to NVMe

subsystems. If this option is enabled only a single

/dev/nvmeXnY device will show up for each NVMe namespace,

This provides support for NVMe hardware monitoring. If enabled,

a hardware monitoring device will be created for each NVMe drive

This provides support for the NVMe over Fabrics protocol using

the RDMA (Infiniband, RoCE, iWarp) transport. This allows you

to use remote block devices exported using the NVMe protocol set.

To configure a NVMe over Fabrics controller use the nvme-cli tool

from https://github.com/linux-nvme/nvme-cli.

If unsure, say N.
