one day. In addition, the following fields are updated after 1:00 PM to reflect the latest data,
which is as follows:
• License Capacity: 50TB, +823TB-Days
• License Status: Installed
• Term (Days): 8
• End Date: 12/09/2010
Eight days count from 12/02/2010
If 100.5TB is used during the second half of 12/04/2010, P9000 Performance Advisor uses
101TB-Days and considers the 0.5 days as one day. In addition, the following fields are updated
after 1:00 PM on 12/05/2010 to reflect the latest data, which is as follows:
• License Capacity: 50TB, +722TB-Days
• License Status: Installed
• Term (Days): 7
• End Date: 12/08/2010
Seven days count from 12/02/2010
So, 722TB-Days remain which you can use for a duration of seven days.
A Meter based Term license is not bound to a specific start and end date. The TB-Days of Meter based
Term license are used according to the quantity of usable capacity that is monitored and only the
duration (number of days) matter. So, you have the flexibility to use the Meter based Term license at
a stretch for X number of days or for a long duration based on your requirement.
Example scenario 4
Consider the following scenario:
1. A P9000 disk array has a usable capacity of 50TB.
2. A Permanent license is installed on 11/15/2010 to monitor the 50TB usable capacity.
3. 5TB-Days are installed on 11/27/2010, because you plan to use another 1TB usable capacity
every day later for five days.
4. If the usable capacity rises beyond the 50TB Permanent licensed capacity on 11/30/2010 and
the additional usable capacity equivalent to 1TB-Days is used every day, P9000 Performance
Advisor uses the 5TB-Days completely by 12/04/2010.
If the additional usable capacity equivalent to more than 1TB-Days is consumed a day, the 5TB-
Days of Meter based Term license is accordingly used. Consider that the usable capacity equi-
valent to 3TB-Days is monitored on 11/30/2010, followed by 2TB-Days on 12/01/2010. As
a result, the 5TB-Days ends by 12/01/2010.
Example scenario 5
Consider the following scenario:
1. A P9000 disk array has a usable capacity of 25TB.
2. A Permanent license is installed on 11/28/2010 to monitor the 25TB usable capacity.
3. 12TB-Days are installed on the same day, because you plan to use another 1TB usable capacity
every day later for 12 days.
4. If the usable capacity rises beyond the 25TB Permanent licensed capacity on 11/30/2010 and
3.5TB is used on the same day, P9000 Performance Advisor considers 4TB-Days.
5. If there has been no activity from 11/30/2010 till 12/28/2010, the remaining 8TB-Days are
not used.
6. If 4TB is used on 12/29/2010 followed by another 4TB on 12/30/2010, P9000 Performance
Advisor considers 4TB-Days on each day, and the 8TB-Days are completely used by 12/30/2010.
