The storage resources underlying the built-in Oracle PCA ZFS storage repository and the server pool clustering file system are listed under the Storage tab within Oracle VM Manager. The internal ZFS storage is exported through NFS and is listed under the File Servers folder. Do not modify or attempt to delete this storage.
Compute node provisioning relies on the internal ZFS file server and its exported storage. Changing the configuration will cause issues with provisioning and server pool clustering.
It is possible to attach additional storage for use within Oracle VM, if you intend to create an additional repository to store virtual machine resources. The options to extend the storage capacity of an Oracle PCA are explained in detail in the Oracle Private Cloud Appliance Installation Guide: refer to the chapter entitled Extending Oracle Private Cloud Appliance - External Storage.
Information on expanding your Oracle VM environment with storage repositories located on the external Fibre Channel or InfiniBand storage is provided in the Oracle VM User's Guide. Refer to the section entitled Managing Storage.
You are also fully capable of using other networked storage, available on the public network, within your own Virtual Machines. The limitations described here apply only to internal ZFS storage used by the Oracle VM environment running within your Oracle PCA.
