Has anyone tried to do this by zoning the tape drives and robot directly to the guest's WWN via NPIV? I would think you would have better success/performance that way than if you vitualized the targets and had the ESX host playing more of a middle man. Just wondering.

Ok - 2 conflicting responses here! If its unsupported, then from a business direction I guess its not a viable option to go this route. (If what you say is right with the I/O then that is the last thing I need).

It is not supported. There are massive problems with the I/O.

It works for me just fine, but I don't think it's supported.

Hi Curtis
Well guess what...... there is a client that is looking at VM'ing Master and Media Servers and want to use a tape drive or robot!
I am under the impression its not supported or works. Your comments seem to reflect this may not be the case.
Can you clarify?
Simon

When you say they don't support, you must mean that they won't give you support on it. All you have to do is create virtual scsi devices for each tape drive/robot device, then you see the robot and drives in the guest OS.
Admittedly, I haven't done it for production, but I haven't found it to be too difficult or unreliable.
BUT, I'm trying to figure out why anyone would do that in production. Performance SUCKS!

A recent exercise with VMware a few months ago brought to light that VMware does NOT support guest access to SAN-based tape drives, and has no plans to do so. Some fiddling around managed to get a guest to see such tape drives, but they did not work reliably at all.
