Re: How low can you go?
Ken you're correct; there is a minimum charge of 3 MSUs for an IBM product per "PricingPlex". That's important because it is not per machine. Al Sherkow I/S Management Strategies, Ltd.

Re: How low can you go?
This is a definite "it depends" not only as to what is running on the LPAR, but also how one determines "minimum". We have 3 LPARs defined on a 4 engine z10BC of 1026 MIPS, 127 MSUs. Our production LPAR has 4 LPs, so it could use all 127 MSUs if going full out. Our development LPAR and our system programmer LPAR are each define with 2 LPs, so that is 63.5 MSUs each. However, they are weighted 750/200/50 which would give a maximum of 95.25/63.5/6.35 if the box is completely maxed out. Our monthly SCRT reports normally show that the system programmers LPAR is using only 1 MSU. However, in one month, when the sys progs were working heavily on a new OS, it went up to 14 MSUs. So - "It Depends".

Re: How low can you go?
SCRT usually shows in the 1 to 3 MSU range although with all LPARs together it's 100-115 If that was my only LPAR I think there is a minimum 3 MSU charge (but I could be wrong). -Original Message- zMan On Wed, May 26, 2010 at 3:16 PM, Ken Porowski wrote: > If you're not hard capping (or have a low softcap) the question is > moot as the LPAR will get what it wants subject to overall box > utilization and weights.

Re: How low can you go?
If you're not hard capping (or have a low softcap) the question is moot as the LPAR will get what it wants subject to overall box utilization and weights. I can define and run fine in an LPAR with a 1/100 share (or smaller) as long as I'm not hard capping. My sysprog LPAR has a defined capacity of 8 MSU and I rarely softcap. -Original Message- zMan What's the smallest usable z/OS LPAR you have, in MSUs?
