RE: Guesting (was LPARS/OS)

Guesting does give you some advantages.  Mainly the lack of hardware 
commitment.  No separate raid controllers.  All disk arms are helping to 
spread the work.  You can incremental amounts of disk on the fly.  This 
disk is exactly like adding disk to IXS cards.

I would like to not have tied up the hardware like this.  I also like the 
thought that an advocate like Erwin L. Earley who might be able to find 
out if there really are issues trying to use tape drives on TSM through 
guested Linux that are just oh so much better on dedicated Linux, or if 
they were grasping at straws.  Then again, Chris Edwards might just say do 
dedicated anyway and stop messing with it.

After all, they may have been right.  One reason TSM was such a disaster 
in pase is because the pase api's to talk to the tape drives sucked so bad 
(from what IBM told me).  But guested Linux is a totally different animal 
than pase.
