The following virtual DVD-ROM types are supported:
Virtual DVD: emulated SCSI DVD-ROM with virtual media comes from a disc inside of a
CD/DVD drive on the VM Host.
Virtual FileDVD: emulated SCSI DVD-ROM with virtual media that comes from a VM Host
ISO file.
Virtual NullDVD (empty): emulated SCSI DVD-ROM with no virtual media currently present.
The next media selection may come from a VM Host CD/DVD drive or VM Host ISO file,
depending on how the Virtual NullDVD is configured. Virtual DVD changes can be initiated
from the virtual console (vMP> IN and EJ commands)
Attached Devices
Integrity VM supports a suite of attached devices to complete data backups from a virtual
machine. Integrity VM attaches these devices using a special Integrity VM pass-through driver.
With this pass-through driver, virtual machine I/O requests are interpreted by Integrity VM and
sent through the virtual storage subsystem to the physical device. The virtual storage subsystem
sends device responses to the Integrity VM pass-through driver, which sends the responses to the
virtual machine. Because the virtual machine can see all the data and responses, support for the
attached physical device must be provided by the guest OS.
The VM Host backup device types are tapes, media changers, and CD/DVD burners.
Integrity VM does not support HFS. NFS is supported but not recommended. Integrity VM
virtualizes SCSI devices. Use hpvmcreate / hpvmmodify to assign storage devices to a virtual
machine.
You can find more info about backing storage devices in the following white papers:

AVIO
The Integrity VM V3.5 release introduced new accelerated storage and networking products to
improve the overall I/O performance for Integrity VM. The new Accelerated Virtual I/O (AVIO)
products provide up to a 60% reduction in service demand and as much as twofold improvement
in throughput over the existing fully virtualized storage and networking Integrity VM solutions.
