Capping

When capping is active for an LPAR, this capping will determine a target MSU for this LPAR. While this capping is activated, the MSU consumption can not be above this target MSU.

Capped by Weight (hard capping)

When a CPC is overcharged, the target MSU for each LPAR depends on their weight. The target MSU formula is:

• Cec capacity * LPAR weight / Sum of active LPAR weight.

Capped by Defined Capacity (soft capping)

When an LPAR has a defined capacity greater than 0, soft capping is activated. This capping caps the LPAR to the DC (Defined Capacity) only if the R4H (Rolling 4 hours) is greater than the DC.

Capped by Logical Processor (absolute capping)

When an LPAR has less logical processors than the cec processors, it can only consume the percentage of processor. For example, if an LPAR has 3 logical processors on a cec that has 10 processors, your LPAR can only consume 30% of the max MSU.
