HP XP Performance Advisor Software - Manual (Page 25)

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, HP XP7 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 HP XP7 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.
