The storage resources underlying the built-in Oracle Private Cloud Appliance 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 listed under the SAN 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.
There are functional differences between the Oracle ZFS Storage Appliance ZS7-2, which is part of systems with an Ethernet-based network architecture, and the previous models of the ZFS Storage Appliance, which are part of systems with an InfiniBand-based network architecture. For clarity, this section describes the Oracle VM storage resources separately for the different storage appliances.
The internal ZFS Storage Appliance has sufficient disk space (100TB) for a basic virtualized environment, but the storage capacity for virtual disks and shared file systems can be extended with additional external storage for use within Oracle VM.
Information on expanding your Oracle VM environment with storage repositories located on the external storage is provided in the Oracle VM Manager User's Guide. Refer to the section entitled Storage Tab. You are also fully capable of using other networked storage, available on the public network or a custom network, within your own Virtual Machines.
While the storage repository on the internal Oracle ZFS Storage Appliance ZS5-ES and earlier models can be used for a basic virtualized environment and for test purposes, the preferred approach for production environments is to attach additional external storage for use within Oracle VM. The options to extend the storage capacity of an Oracle Private Cloud Appliance are explained in detail in the Oracle Private Cloud Appliance Installation Guide: refer to the chapter entitled Extending Oracle Private Cloud Appliance - Additional 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 Manager User's Guide. Refer to the section entitled Storage Tab. You are also fully capable of using other networked storage, available on the public network or a custom network, within your own Virtual Machines.
