HP StorageWorks P9000 Application Performance Extender Software User Guide (5697-0984, September 2012)

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
Application Performance Extender 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
- List of existing licenses section display:
Description
Column Headings - List of existing licenses
section
50TB, 0TB-Days
This is because, 90TB-Days are completely used by
12/11/2010.
License Capacity
Displays 0.
Zero days, as there are no TB-Days to use.
Term (Days)
Displays Capacity Insufficient.
License Status
Displays Expired.
End Date
The License Capacity continues to display every day reduction in TB-Days till 02/08/2011 (60th day).
The remaining fields listed in the above table remain the same.
• On 12/12/2010, the License Capacity shows 50TB, –10TB-Days
• On 12/13/2010, the License Capacity shows 50TB, –20TB-Days
• On 02/08/2011, the License Capacity shows 50TB, –590TB-Days
NOTE:
If 90TB-Days are completely used in the second half of 12/11/2010, P9000 Application Performance
Extender enters 60 days grace period on the same day but updates the License screen - List of existing
licenses section only after 1:00 PM on 12/12/2010. In this case, the License Capacity shows 50TB,
–10TB-Days on 12/12/2010.
For information on calculating the appropriate TB-Days to end the grace period and also read
additional scenarios, see “Exceeding Meter based Term licensed capacity and grace
period” on page 42.
A Meter based Term license least count is 1TB-Days. By default, fractions of a TB of usable capacity
is considered as 1TB and fractions of a day is considered as one day.
Example scenario 3
Consider the following scenario:
1. A P9500 disk array has a usable capacity of 50TB.
2. A Permanent license is installed on 11/20/2010 to monitor the 50TB usable capacity.
3. Another 100TB usable capacity is added on 11/30/2010 and must be monitored for 10 days.
