======================
Ceph NVMe-oF Gateway
======================
The NVMe-oF Gateway presents an NVMe-oF target that exports
RADOS Block Device (RBD) images as NVMe namespaces. The NVMe-oF protocol allows
clients (initiators) to send NVMe commands to storage devices (targets) over a
TCP/IP network, enabling clients without native Ceph client support to access
Ceph block storage.
Each NVMe-oF gateway consists of an `SPDK <https://spdk.io/>`_ NVMe-oF target
with ``bdev_rbd`` and a control daemon. Ceph’s NVMe-oF gateway can be used to
provision a fully integrated block-storage infrastructure with all the features
and benefits of a conventional Storage Area Network (SAN).
