Block Storage provides an infrastructure for managing +volumes, and interacts with OpenStack Compute to provide volumes for +instances. The service also enables management of volume snapshots, and +volume types. + +The Block Storage service consists of the following components: + +cinder-api + Accepts API requests, and routes them to the ``cinder-volume`` for + action. + +cinder-volume + Interacts directly with the Block Storage service, and processes + such as the ``cinder-scheduler``. It also interacts with these processes + through a message queue. The ``cinder-volume`` service responds to read + and write requests sent to the Block Storage service to maintain + state. It can interact with a variety of storage providers through a + driver architecture. + +cinder-scheduler daemon + Selects the optimal storage provider node on which to create the + volume. A similar component to the ``nova-scheduler``. + +cinder-backup daemon + The ``cinder-backup`` service provides backing up volumes of any type to + a backup storage provider. Like the ``cinder-volume`` service, it can + interact with a variety of storage providers through a driver + architecture. + +Messaging queue + Routes information between the Block Storage processes. diff --git a/doc/source/install/index.rst b/doc/source/install/index.rst index a88080c06cd..91e44d7c528 100644 --- a/doc/source/install/index.rst +++ b/doc/source/install/index.rst @@ -19,6 +19,7 @@ For more information, see the .. toctree:: + get-started-block-storage index-obs index-rdo index-ubuntu
