You can configure virtual hard disks as IDE or SATA disks for any guest operating system. You can set up a virtual hard disk as a SCSI disk for any guest operating system that has a driver for the LSI Logic or BusLogic SCSI adapter. You can also set up a virtual hard disk as an NVMe disk for any guest system that includes NVMe drivers. You determine which SCSI adapter to use when you create a virtual machine.
The files that make up an IDE, SATA, SCSI, or NVMe virtual hard disk can be stored on a hard disk of any type. They can also be stored on other types of fast-access storage media.
To use SCSI hard disks in a 32-bit Windows XP virtual machine, you must download a special SCSI driver from the VMware Web site. Follow the instructions on the Web site to use the driver with a fresh installation of Windows XP.
