The aggregate term for the people, software, mission and infrastructure
of Ceph.

newer versions). Unlike :term:`filestore` it stores objects
directly on the Ceph block devices without any file system
interface.

The S3/Swift gateway component of Ceph.
Ceph Block Device
RBD
The block storage component of Ceph.
Ceph Block Storage
The block storage "product," service or capabilities when used in
conjunction with ``librbd``, a hypervisor such as QEMU or Xen, and a
hypervisor abstraction layer such as ``libvirt``.
