You configure virtual SCSI controllers on your virtual machines to attach virtual disks and RDMs to.
The choice of SCSI controller does not affect whether your virtual disk is an IDE or SCSI disk. The IDE adapter is always ATAPI. The default for your guest operating system is already selected.
Changing the SCSI controller type might result in a virtual machine boot failure.
Verify that you are familiar with the limitations and conditions for configuring SCSI controllers. See SCSI and SATA Storage Controller Conditions, Limitations, and Compatibility.
