Oracle Solaris Zones, Oracle VM Servers for SPARC, Oracle VM Servers for x86, their server pools, and virtual datacenters store their metadata and their operational data in storage libraries.
Use Oracle Enterprise Manager Ops Center to create and modify storage libraries and change the storage capacity. Manage and monitor storage servers and appliances, discover and provision storage capacity on these appliances, and then make the storage available to virtual assets through its storage libraries.
Opaque storage: When Oracle Enterprise Manager Ops Center discovers a virtualization host or virtual host that uses storage that is not backed by a managed asset, Oracle Enterprise Manager Ops Center can identify the virtual disks used by the host and can share them with other hosts of the same type.
Multipath storage: You can create more than one path from a logical domain to its storage to ensure that the logical domain continues to operate if one path is not accessible. Using multiple I/O Domains provides this redundant access.
