Re: LPAR on very small machines

[Al Barsa <barsa@xxxxxxxxxxxxxxxxxxx>]

My 520 has .43 processors (isn't that user friendly), and each processor
can support up to 10 partitions.  So 264 partitions will not come from a 16
processor system.

That sounds like building two machines.

I have assumed for a long while that LPAR required
a "great deal" of planning to make it work. I often
wondered about this after seeing the chart that shows
up to 256 partitions on a single machine. That's gonna
require a few extra parts.
