Block Storage service

Block Storage service

The Block Storage service (cinder) provides block storage devices to guest instances. The method in which the storage is provisioned and consumed is determined by the Block Storage driver, or drivers in the case of a multi-backend configuration. There are a variety of drivers that are available: NAS/SAN, NFS, iSCSI, Ceph, and more.

The Block Storage API and scheduler services typically run on the controller nodes. Depending upon the drivers used, the volume service can run on controller nodes, compute nodes, or standalone storage nodes.
