Storage

This component, based on the OpenStack Cinder Service, allows the management of the storage space in cloud projects.

Storage in CINECA HPC Cloud machines is based on Ceph platform. Ceph provides reliable distributed and scalable storage without a single point of failure.

Within OpenStack, it is possible to create different block storage devices, that can be used by instances (virtual machines) to store data persistently.

Volumes

A volume is a block storage device that can be attached to instances. It provides persistent storage for data.

Snapshots

A snapshot is a point-in-time copy of a volume. It can be used to create new volumes or restore existing volumes. Snapshots use the Copy On Write (COW) technique to create lightweight snapshots of volumes.

Backups

A volume backup is a copy of a volume that can be used to restore data in case of data loss or corruption (NOT IN FULL PRODUCTION).
