Challenges - Economically
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)
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

FC Switch Port
Because of a Zoning n-Host Ports to 1 Storage Port
there might be a performance issue
Shortages at Metro
Mirror connections
have an immediate
impact to all mirrored
Client LPARs !!

Power Server Bus Utilization
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

information is possible
Requirements are highly dependent to the usage of each
system and might differ a lot between customers !!

Monitoring (Availability)
Monitoring the Availability of all Components
Producing a list of all Errors of the following components:
HMC
VIO Server
FC Switch
all Serviceable Events
all Error Log Entries
e.g. CRC, ENC, Trunk Error, BBC 0, …
Notification in the case of Events via E-Mail
