HP Integrity Virtual Machines Installation, Configuration, and Administration

7.2.1.1 VM Storage Supportability
Before you configure virtual machine storage, make sure the VM Host storage can be supported
by the virtual machine.
• All VM Host storage available for use by a VM must meet support requirements for the
Integrity server and OS version that comprise the VM Host. If the physical storage is not
supported by the VM Host, it is not supported for use by a virtual machine.
• All VM Host storage available for use by a VM must be connected with one of the following
adapter and driver types:
— Fibre Channel adapters supported by the TD driver
— Fibre Channel adapters supported by the FCD driver
— SCSI adapters supported by the C8xx driver
— SCSI adapters supported by the MPT driver
— SCSI adapters supported by the CISS driver
— IDE adapters supported by the SIDE driver
— USB adapters supported by the UsbScsiAdaptor driver (virtual devices only — see
Section 7.1.3.2.1: “Virtual Devices” (page 73))
— SAS adapters supported by the SASD driver
— iSCSI adapters supported by the ISCSI driver
If the physical storage is not connected with one of above adapter and driver types, it cannot
be used by a virtual machine. Use the ioscan command to display the VM Host storage
that is connected to adapters and drivers.
• Any VM Host attachable devices available for use by a virtual machine must be supported
by the guest OS it is attached to. If the physical device is not supported by the guest OS, the
device cannot be attached to the virtual machine.
7.2.1.2 Performance of Virtual Devices
To meet the performance requirements of applications running in guests, consider the potential
performance of each type of Integrity VM storage device.
Different types of virtual media have different effects on the performance of the virtual device
because they communicate differently with the VM Host to complete virtual machine I/O
operations. To understand the effect of the virtual device type on potential performance, consider
the Integrity VM storage I/O stack illustrated in Figure 7-1.
