� How utilized is my current investment ??
� How many additional customers / systems can I move
to the existing Hardware ??
� When will be the time for the next investment ??
� Which investment will deliver the best price /
performance ratio ??

Monitoring (Performance)
6
� 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

Power Server Bus Utilization
14 22.11.2013IT-Power Services
� Dependent on the used HW it is possible to monitor the
utilization of the System Bus (connection between
system unit and expansion drawers)
� It is important to avoid in balances of the System Bus

Client LPAR Utilization
15 22.11.2013IT-Power Services
� Analysis and graphical
presentation of all
Performance
information is possible
� Requirements are highly dependent to the usage of each
system and might differ a lot between customers !!
