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).
