Effective term = remaining licensed capacity of meter key / (used capacity
- licensed capacity of permanent key)
If the used capacity is within the licensed capacity of the permanent key, the license of the meter
key is not used, and the expiration date for use is not displayed. An example is shown next.
Example of licensed capacity of permanent key >= used capacity
The meter license is not used. Therefore, the licensed capacity of the meter key is not subtracted.
Meter is displayed in the key type field, and Installed is displayed in the status field.
Example of licensed capacity of permanent key + licensed capacity of meter
key >= used capacity
The meter license is used, and the licensed capacity of the meter key is subtracted. Meter is displayed
in the key type field, and Installed is displayed in the status field.
If the used capacity is 4TB, the licensed capacity of the permanent key is 3TB, and the licensed
capacity of the meter key is 2TB, the effective term is 2 days.
Remaining licensed capacity of meter key / (used capacity - licensed
capacity of permanent key )
= 2TB / (4TB - 3TB)
= 2 days
Example of licensed capacity of permanent key + licensed capacity of meter
key < used capacity
The meter license is used, and the licensed capacity of the meter key is subtracted. Meter is displayed
in the key type field, and Grace Period is displayed in the status field.
