HP StorageWorks P9000 Performance Advisor Software v5.4 User Guide (T1789-96328, April 2012)

Description
Column Headings - License
Status section
Displays Never.
This is because, the Permanent license which is for an unlimited duration
is currently active.
End Date
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 P9000 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
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.
License Capacity
Displays 8.
Eight days is the remaining duration when the +80TB-Days can be used.
Term (Days)
Displays the status as Installed.
License Status
Displays 12/10/2010.
Calculated as eight days starting from 12/03/2010.
End Date
Consider that the usable capacity exceeds the 50TB Permanent licensed capacity by 10TB in the
second half of 12/03/2010. As a result, P9000 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,
P9000 Performance Advisor enters 60 days grace period for that particular P9000 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, P9000 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 P9000 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, P9000
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.
