RE: LPAR for testing on a relatively small machine?

Hear hear!
I have a 9408-M25 with one "host" partition running 7.1 and two guested 
partitions underneath that with both also running 7.1.  They also ran 
happy when all were at 6.1.
Guesting allows all partitions to share all available disk arms.

Screw separate controllers for each partition!  Screw taking the disk arms 
and divvying them up by partition!  Stick a CD in the CD drive and all 
three simultaneously report that volume id is now in the drive.

Power 6 and 6.1 (or above) rocks!  Love having that HMC also.

We keep our percent used on our machines really low.  Amazingly low.

MAIL3:  Hosting partition
Only partition with "real" disks.
