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.
Meter based Term license requirement
Meter based Term licenses are useful when you want 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

P9000 disk array of 75TB usable capacity. A Permanent license is installed on 01/01/2010 to

January'10 time frame due to Christmas and New Year celebrations, the company is expecting a
surge in the online booking traffic beginning December'10 and continuing till the end of 1st week of
January'11. The company is confident that at least 50TB additional usable capacity is required during
this time frame (estimated 39 days).
In such cases, the company has two options:
•
Generate and install a Meter based Term license, as the 50TB spike in usable capacity is for a
limited duration.
•
Generate and install a Permanent license for the 50TB usable capacity.
Because the 50TB usable 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 usable capacity, it is
