A GSX Server virtual machine can use up to four IDE devices and up to seven SCSI devices. Any of these devices can be a virtual hard disk or DVD or CD-ROM drive. A virtual machine can read data from a DVD-ROM disc. GSX Server does not support playing DVD movies in a virtual machine.

Many other SCSI devices can be connected to a virtual machine using the host operating system's generic SCSI driver. For details on connecting these devices, see Connecting to a Generic SCSI Device.

The following sections describe how to add virtual disks, physical disks, DVD-ROM/CD-ROM drives and floppy drives to virtual machines. In addition, you can connect CD-ROM and floppy drives to disk image files.
