This patch implements the NVMe over TCP host driver. It can be used to connect to remote NVMe over Fabrics subsystems over good old TCP/IP. The driver implements the TP 8000 of how nvme over fabrics capsules and data are encapsulated in nvme-tcp pdus and exchaged on top of a TCP byte stream. nvme-tcp header and data digest are supported as well. To connect to all NVMe over Fabrics controllers reachable on a given taget port over TCP use the following command: nvme connect-all -t tcp -a $IPADDR This requires the latest version of nvme-cli with TCP support.

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.

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

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.
