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".
