Vmware Client Drive type confusion ?

Hi All,

What is the difference between Emulate IDE or Passthrough IDE in vSphere client ?

when to use each type over the other ?

¦ Passthrough IDE (raw). Use mode only for remote client device access.
You can write or burn a remote CD only through pass-through mode access.
Passthrough mode is not functional for local host CD-ROM access.

¦ Emulate IDE. Use to access a host CD-ROM device.
The host CD-ROM device is accessed through emulation mode.
In emulation mode you can only read a CD-ROM from a host CD-ROM device.

If you have a CD device on your ESXi host you can use Emulate IDE mode to read it.
This gives you a functionality of just read.

If you have an ISO on a CD Drive on a Desktop from which you are accessing VM using the vSphere client, you will have to use Pass through mode. This gives you the functionality of both read and write(burn).
