Re: LPAR Question

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

Mark,

 Then you are on target!  However I would challenge your assertion that 
two boxes are cheaper than one.

No. of Cabinets is same or less for LPAR
Amount of memory is same or less for LPAR
Quantity of Disks is generally the same.
Quantity of IOAs is generally the same, sometimes less.
Quanityt of Tape drives is generally the same, sometimes less.
Amount of CPW purchased is often Less

Cost of Maintenance, OS features, and support is almost Always 
significantly less.

Cost of installation is the only area where LPAR is slightly higher and 
that's a OTC.
