HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

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 Performance Advisor 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 Performance Advisor 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.
The following figure illustrates the use of Meter based Term license.
At the time of installing the Meter based Term license, if the usable capacity is within the Permanent
licensed capacity, the installed TB-Days remain dormant till the usable capacity exceeds the Permanent
licensed capacity. They are activated only after the Permanent license is completely used. The TB-Days
are used for the duration when the usable capacity exceeds the installed Permanent licensed capacity
and the exceeded capacity can be managed by the installed TB-Days.
