HP StorageWorks P9000 Application Performance Extender Software User Guide (5697-0984, September 2012)

used only till the first week of January'11, after which it remains unused until the 75TB current usable
capacity increases by 50TB, and is constantly used.
Following is the suggested Meter based Term license configuration:
Generate 1950TB-Days of Meter based Term license to monitor 50TB additional usable capacity for
39 days. The 1950TB-Days are derived based on the following calculation:
50TB * 39 days = 1950TB-Days of Meter based Term license
The following figure illustrates the scenario described.
So, 50TB usable capacity is monitored every day beginning December'10 for the next 39 days. After
the spike in usable capacity reduces to 75TB, P9000 Application Performance Extender uses the
existing Permanent license that is already installed. So, the company has managed the short duration
spike in usable capacity with Meter based Term license and also retained the Permanent license to
monitor the existing 75TB usable capacity.
Example scenario 2
Consider the scenario of another company that has to use P9000 Application Performance Extender
to monitor a P9500 disk array (5TB usable capacity) for a duration of only 180 days. It is a one-time
activity for a specific project. As it is a time bound project, Meter based Term licenses are
recommended. Following is the suggested configuration:
1. Generate and install 1TB Permanent license.
Out of the 5TB usable capacity, 1TB is managed by the Permanent license.
2. Generate and install 720TB-Days Meter based Term license to monitor the additional 4TB usable
capacity for 180 days.
4TB * 180 days = 720TB-Days Meter based Term license
Meter based Term license activation and consumption
Similar to a Permanent license, a Meter based Term license is also bound to the disk array serial
number and the usable capacity for which the license is generated. Once installed, you can use the
TB-Days to monitor the additional usable capacity based on your requirement. For example, if 90
TB-Days Meter based Term license are installed, you can use the 90TB-Days in any of the following
ways:
• 90TB-Days to monitor 90TB additional usable capacity in one day.
• 90TB-Days to monitor 1TB additional usable capacity for 90 days.
• 90TB-Days to monitor 10TB additional usable capacity for nine days.
• Any usage where the duration (Y days) multiplied by the additional usable capacity (XTB) equals
90TB-Days.
