4 Planning with Capacity Advisor
Getting ready
In order to get maximum value from the Capacity Advisor tools, it is important to:
•
Be familiar with the HP SIM framework
• Be familiar with the basic operation of Capacity Advisor
• Be familiar with Virtualization Manager
• Have a clear question you are trying to answer
• Have plenty of utilization data collected for Capacity Advisor
• Have appropriate access roles on the servers about which you are developing the plan
• Understand the equipment well enough to know what is physically possible (such as the
maximum number of CPU cores) and what is practical (such as when to use 1 GB DIMMs
with lots of slots versus when 4 GB DIMMs are more appropriate.) HP software can account
for various power saving associated with specific DIMM.
In addition, it can be very valuable to collect data on a test system to understand the real utilization
characteristics of the applications you are considering.
