Meter Based Term licenses
NOTE:
Meter based Term licenses are applicable for P9000 disk arrays only.
Meter based Term licenses are secondary licenses that you generate at the HPAC website and install
as add-on licenses in P9000 Performance Advisor to monitor additional usable capacities. Meter
based Term licenses cannot work independently and always need to be installed on a Permanent
license. They are not a replacement to the Permanent license.
A Meter based Term license is generated in TB-Days for the usable capacity that you want to monitor
and the duration for which you want to monitor. To calculate the total TB-Days of Meter based Term
license that you require, use the following formula:
Usable capacity * Duration (number of days)= TB-Days Meter based Term
license
IMPORTANT:
• Additional usable capacity refers to the usable capacity that is beyond the Permanent licensed
capacity.
• A Meter based Term license cannot be installed on multiple management stations.
• Multiple Meter based Term licenses can be generated and installed on a management station. In
such cases, the licenses are used successively.
For more information on generating and installing Meter based Term license, see “Generating licenses
at the HPAC license key website” on page 36 and “Installing licenses” on page 37.
Meter based Term license requirement
Meter based Term licenses are useful when you want to monitor an additional usable capacity for a
defined duration or when there is an unplanned surge in the usable capacity that might subsequently
reduce. For steady state license requirements, use Permanent licenses. For dynamic license requirements
arising out of varying business needs, use appropriate TB-Days of Meter based Term license.
IMPORTANT:
For the installed TB-Days to function properly, you must install a minimum of 1TB Permanent license.
The following image illustrates the above mentioned cases.
