HP XP Performance Advisor Software - Manual (Page 29)

•
Term (Days): 9
•
End Date: 12/10/2010
Nine days count from 12/02/2010
If 85.5TB is used during the first half of 12/03/2010 and no additional TB-Days are used
for the rest of the day, HP XP7 Performance Advisor uses 86TB-Days and considers the 0.5
days as 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, HP XP7 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. An XP7 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, HP XP7
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
equivalent 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. An XP7 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.
