Tutorial sulla configurazione di CEPH + CINDER per il block
storage di OpenStack
• Creazione di backend multipli (in particolare CEPH)
• Configurazione di QoS per rate-limiting
• Encryption
• esempi: uso del driver LVM ed RBD
• Backup su Ceph [bonus: metadata import/export]
• Volume retype, migration
