About the Shared Storage Option
The Shared Storage Option allows multiple NetBackup media servers to share
individual tape drives (standalone drives or drives in a robotic library). NetBackup
automatically allocates and unallocates the drives as backup and restore operations
require.
The Shared Storage Option is a separately licensed and a separately priced
NetBackup software option which allows drive sharing. The license key is the
Shared Storage Option key.
The Shared Storage Option is required only if multiple hosts share drives. For
example, multiple NDMP hosts may share one or more drives.
The Shared Storage Option requires appropriate hardware connectivity, such as
Fibre Channel hubs or switches, SCSI multiplexors, or SCSI-to-fibre bridges.
You can use Shared Storage Option in the following environments:
■ Fibre Channel SANs
