This is for those out there who have an understanding on the subject and how it might apply to a non-production service provider environment.
Scenario Example 2964-605 processor Rated MSU = 577 5 CPs are shared among all LPARs Customer-A has LPARs 1,2 & 3 grouped with a MSU cap of 300 (contracted MIPS converted to MSUs). Customer-B has LPARs 6,7,8 & 9 grouped with a MSU cap of 250 (contracted MIPS converted to MSUs). Is the 4HRA at the CEC level or the LPAR level? If the Customer-A LPAR group spikes above its group MSU cap while the Customer-B LPAR group is in low usage, what happens when the Customer-B LPAR group now needs resources? Does it have to wait on Customer-A’s 4HRA to complete or does it get what it needs by taking back the overage given to the Customer-A LPAR group? These may be juvenile questions, but I’m not a capacity planner and I’m trying to gain some understanding of how this works by reading manuals. Any insight will be appreciated. Thanks, S.
