To access virtual disks, a virtual machine uses virtual SCSI controllers. Each virtual disk that a virtual machine can access through one of the virtual SCSI controllers resides in the VMFS datastore, NFS-based datastore, or on a raw disk. The choice of SCSI controller does not affect whether your virtual disk is an IDE or SCSI disk.
The wizard preselects the correct default controller based on the guest operation system you selected on the Guest Operating System page.
LSI Logic SAS and VMware Paravirtual controllers are available only for virtual machines with hardware version 7 or later. For details about VMware Paravirtual controllers, including conditions for use and limitations, see About VMware Paravirtual SCSI Controllers.
Disks with snapshots might not experience performance gains when used on LSI Logic SAS and LSI Logic Parallel controllers.
- On the SCSI Controller page of the New Virtual Machine wizard, accept the default or select a SCSI controller type.
