An End-to-End monitoring solution for a fully virtualized Power Server environment. This tool includes performance as well as availability monitoring for all involved parts, e.g. V7000, FC switches, VIO Server (SEA as well as FC), Power Server bus utilization and the final client LPAR (IBM i, iSeries, AS400, AIX, LINUX). Available for a broad range of hardware products, including e.g. High End IBM Power 795 installations using IBM DS8000 external storage, as well as IBM Power 720 using any external storage products from various different vendors.

4. 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 ??

6. 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

10. VIOs Utilization – Fiber Channel
Important is to recognize immediately which Client LPAR
is causing which part of the work load
Individual LPAR !!

13. 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 !!

14. 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 !!
