I can't get to SHARE. I'm semi-retired and on an extremely limited
budget. Contact me off-list and perhaps we can talk.

Under VM does have another layer, true. But not so different. Especially on System z and current version of z/VM. Rather than type long winded messages, I can set up a call. Or we can chat at Share in a couple of weeks.

Subject: Re: 2 versus 4 processors
--------------------------------------<snip>------------------------------------
I am sorry but I don't understand what you mean.
We are a software development company so our work has no standard at
all. It changes from day to day depending on what the developers are
doing. We have a 2096 n02 which gives us 2 106(?) mips CP's. We have to
run our sysplex testing by running sysplex under z/VM.
We have the opportunity to hopefully get a 2098 g04, each processor will
have 62.5 Mips (?) per CP. As I would like to be able to create a real
sysplex and play around with various configurations I believe hat 4 CP's
would be a very good idea. The PTB's are unsure and are worried that
having CP's will be a big overhead. I don't know where they get this
feeling.
I would like opinions, as to even worst case, we would be worse off if
I kept current LPAR lay out on 4 CP's as against 2 CP's where all LPARs
share CP's equally. I can't be very precise because the target changes
day to day
---------------------------------<unsnip>----------------------------------
The very fact that you're running your sysplex under z/VM introduces a
whole new level of complexity to the problem, which some of us can't
address.
Query: why under z/VM??
