Re: LPAR - micro partitioning an i5-520

What IBM did with the new 5xx boxes is told you about the number of
processors they were going to let you use, and then told the truth about
it.  Had they sold you .32 processors, and rounded it to 1.0 (by
multiplying everything (by multiplying everything by 3.13,) no one would
have been upset, but they didn't do that; and it would have caused a very
complicated set of rules about the amount of processor you would need per
partition.

Hello *ALL,
would someone be so kind to explain some LPAR-details to me ?
I tried to configure LPARs with Virtual Partition Manager for a quite
simple goal:
Given a one processor i5-520-machine,  i5-OS V5R3 or V5R4 we want to add
one or more Linux partitions.
Why is the number of processor units = 0.32 ???
Does this mean, I won't be able to give my linux partition a tenth of
processor
power, because I am not able to divide my 0.32 to something smaller than
0.22 units for my i5-OS partition and 0.10 units for my Linux ?
I always thought 0.10 is the minimum for micro partitioning a single POWER5
processor and since whe have one processor its processor units have to
be 1.00 ??? What am I missing here ?
The VPM Redbook is not helpful at all ...

Any hint welcome.
Regards from Germany,
Philipp
