The Cinder in City Cloud is designed to create and manage a service that provides persistent data storage to cloud computing applications.
City Cloud Block Storage provisions and manages block devices known as Cinder volumes.
Under a typical scenario, Cinder volumes provide persistent storage to guest virtual machines, also known as instances, that are managed by City Cloud Compute module.
Cinder can also be used independent of other City Cloud services as stand-alone software-defined storage. (Is this true for City Cloud?)
Cinder features basic storage capabilities, such as replication, snapshot management and volume clones.
In City Cloud, Cinder is utilizing the Ceph RBD (RADOS Block Device) driver.
