• Generate and install a Meter based Term license, as the 50TB spike in physical usable capacity is for
a limited duration.
• Generate and install a Permanent license for the 50TB physical usable capacity.
Because the 50TB capacity is required for a short duration, it is economical to install TB-Days of Meter
based Term license. If a Permanent license is installed for the 50TB physical usable capacity, it is used
only till the first week of January'11, after which it remains unused until the 75TB current physical 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 physical 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 physical usable capacity is monitored every day beginning December'10 for the next 39 days.
After the spike in physical usable capacity reduces to 75TB, PA uses the existing Permanent license that
is already installed. So, the company has managed the short duration spike in physical usable capacity
with Meter based Term license and also retained the Permanent license to monitor the existing 75TB
physical usable capacity.
Example scenario 2
Consider the scenario of another company that has to use PA to monitor a P9500 Disk Array (5TB
physical 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.
1. Generate and install 1TB Permanent license.
Out of the 5TB physical usable capacity, 1TB is managed by the Permanent license.
2. Generate and install 720TB-Days Meter based Term license to monitor the additional 4TB physical
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 physical usable capacity for which the license is generated. Once installed, you can use the TB-
Days to monitor the additional physical usable capacity based on your requirement. For example, if 90
