HP XP P9000 Performance Advisor Software - Manual (Page 39)

5. As the usable capacity is beyond the Permanent licensed capacity, HP XP P9000 Performance
Advisor uses the 100TB-Days of Meter based Term license.
Based on the usable capacity consumed, HP XP P9000 Performance Advisor uses the
appropriate TB-Days of Meter based Term license. Following are sample consumptions from
day 1 to day 3:
•
11/30/2010: 51.5TB monitored using 52TB-Days
•
12/01/2010: 20.3TB monitored using 21TB-Days
•
12/02/2010: 24.9TB monitored using 25TB-Days
6. As 4TB usable capacity is remaining and only 2TB-Days are available, HP XP P9000
Performance Advisor does the following:
a.
Enters 60 days grace period after 1:00 PM on 12/02/2010 and updates the following
fields with the latest TB-Days data:
•
License Capacity: Displays 75TB, +2TB-Days
•
License Status: Capacity Insufficient
•
Term (Days): 0
•
End Date: Expired
b. Begins reducing the installed TB-Days by 20TB every day starting from 12/03/2010,
which is shown as follows:
•
On 12/03/2010, 2TB-Days are reduced to –18TB-Days
•
On 12/04/2010, –18TB-Days are reduced to –38TB-Days
•
On 12/05/2010, –38TB-Days are reduced to –58TB-Days
7. The reduction in TB-Days continues till you install the appropriate TB-Days of Meter based
Term license, so that HP XP P9000 Performance Advisor does the following:
•
Shows positive TB-Days
•
Ends the grace period for the particular P9000 disk array
8. So, if you want to install TB-Days on 12/05/2010 for a duration of five days, generate
160TB-Days of Meter based Term license. Out of the 160TB-Days:
•
60TB-Days (3 days * 20TB) are used to nullify the reduction in installed TB-Days.
•
100TB-Days (5 days * 20TB) is required for HP XP P9000 Performance Advisor to continue
monitoring the 20TB usable capacity for another five days.
With 160TB-Days, HP XP P9000 Performance Advisor ends the grace period and continues
to monitor the 20TB usable capacity for another five days.
Violating licensed capacity
After 60 days of grace period, HP XP P9000 Performance Advisor considers it as a capacity
violation and stops configuration data collection for any additional internal raw disk or usable
capacity. It continues the existing performance data collection.
