   9           The NVM Express driver is for solid state drives directly
  10           connected to the PCI or PCI Express bus.  If you know you
  11           don't have one of these, it is safe to answer N.
  12
  13           To compile this driver as a module, choose M here: the
  14           module will be called nvme.

  16 config BLK_DEV_NVME_SCSI

  18         depends on NVME_CORE
  19         ---help---
  20           This adds support for the SG_IO ioctl on the NVMe character
  21           and block devices nodes, as well as a translation for a small
  22           number of selected SCSI commands to NVMe commands to the NVMe
  23           driver.  If you don't know what this means you probably want
  24           to say N here, unless you run a distro that abuses the SCSI
  25           emulation to provide stable device names for mount by id, like
  26           some OpenSuSE and SLES versions.

  38           This provides support for the NVMe over Fabrics protocol using
  39           the RDMA (Infiniband, RoCE, iWarp) transport.  This allows you
  40           to use remote block devices exported using the NVMe protocol set.
  41
  42           To configure a NVMe over Fabrics controller use the nvme-cli tool
  43           from https://github.com/linux-nvme/nvme-cli.

  45           If unsure, say N.
