HP XP Performance Advisor Software - Manual (Page 27)

Consider that the usable capacity exceeds the 50TB Permanent licensed capacity by 10TB in the
first half of 12/03/2010. As a result, the 90TB-Days are activated and HP XP7 Performance
Advisor uses 10TB-Days, and updates the following fields after 1:00 PM on the same day.
On 12/03/2010:
Description Column Headings - License Status section
Displays 50TB, +80TB-Days License Capacity
This is because, 10TB-Days are used on 12/03/2010 to
monitor the additional 10TB usable capacity on that day.
It also indicates that +80TB-Days remain that can be used.
Displays 8. Term (Days)
Eight days is the remaining duration when the +80TB-Days
can be used.
Displays the status as Installed. License Status
Displays 12/10/2010. End Date
Calculated as eight days starting from 12/03/2010.
Consider that the usable capacity exceeds the 50TB Permanent licensed capacity by 10TB in the
second half of 12/03/2010. As a result, HP XP7 Performance Advisor updates the above listed
fields after 1:00 PM only on the next day (12/04/2010), though the 10TB-Days are already used
from the 90TB-Days on 12/03/2010.
After the installed TB-Days are completely used and one of the following actions is not completed,
HP XP7 Performance Advisor enters 60 days grace period for that particular XP7 disk array:
•
A Permanent or appropriate TB-Days of Meter based Term license installed to monitor the
additional usable capacity.
•
The additional usable capacity reduced to match the Permanent licensed capacity.
In addition, HP XP7 Performance Advisor reduces the installed TB-Days every day after 1:00 PM
till one of the above-mentioned actions is performed. The reduction (negative count) of TB-Days is
proportional to the additional usable capacity that needs to be monitored. After 60 days, a capacity
violation is reported and HP XP7 Performance Advisor stops monitoring that disk array.
Consider that the 90TB-Days are completely used in the first half of 12/11/2010 and appropriate
TB-Days are not yet installed to monitor the 10TB additional usable capacity. As a result, HP XP7
Performance Advisor does the following:
1. Enters 60 days grace period at 1:00 PM on the same day and 0TB-Days are available.
2. Begins reduction (negative count) of installed TB-Days.
The reduction continues for the next 59 days and the every day reduction is proportional to the
10TB additional usable capacity that needs to be monitored. After 60 days, a capacity violation
is reported.
After 1:00 PM on 12/11/2010 (Day 1 of grace period), the following fields on the License screen
- License Status section display:
Description Column Headings - License Status section
50TB, 0TB-Days License Capacity
This is because, 90TB-Days are completely used by
12/11/2010.
Displays 0. Term (Days)
Zero days, as there are no TB-Days to use.
