Storage Classes
The storage objects are separated into three types: controllers, drives, and media.
There are two controllers, an emulated IDE controller and a synthetic SCSI controller. Both controllers support the attachment of drives that host the media.
The following are virtualization WMI classes related to storage. There is also support for synthetic floppy disk media. Attaching to a physical floppy drive is not supported.
