All tenancies receive a total of 200 GB of Block Volume storage, and five volume backups included in the Always Free resources. These amounts apply to both boot volumes and block volumes combined. When you provision a compute instance, the instance automatically receives a 50 GB boot volume for storage. You can also create and attach block volumes to expand the storage capacity of a compute instance. For more information, see Creating a Block Volume and Attaching a Block Volume to an Instance.
