Components

The Rook-Ceph operator manages a number of components as part of the Fusion Data Foundation deployment.

Ceph-CSI Driver

The operator creates and updates the CSI driver, including a provisioner for each of the two drivers, RADOS block device (RBD) and Ceph filesystem (CephFS) and a volume plugin daemonset for each of the two drivers.

Ceph daemons

Mons

The monitors (mons) provide the core metadata store for Ceph.

OSDs

The object storage daemons (OSDs) store the data on underlying devices.

Mgr

The manager (mgr) collects metrics and provides other internal functions for Ceph.

RGW

The RADOS Gateway (RGW) provides the S3 endpoint to the object store.

MDS

The metadata server (MDS) provides CephFS shared volumes.
