# 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.
