� Top-Down Approach
� Layer 1 (Impact to all client LPARs):
� Power Server utilization (e.g. LPAR2RRD)
� Storage Utilization
� Layer 2 (Impact to “some” Client LPARs):
� VIOs Performance Utilization (FC, SEA)
� FC Switch Port
� Power Server Bus Utilization
� Layer 3 (Impact to one Client LPAR):
� Client LPAR Utilization
