1 Overview
In a typical Storage Area Network (SAN) environment, multiple I/O intensive applications share
storage resources. Not all applications are mission critical, but they compete with the mission critical
applications for the same I/O processing requirements. In such situations, there is a need to keep the
key (mission critical) applications at a desired performance level and other (non critical) applications
at an acceptable performance level.
P9000 Application Performance Extender enables you to monitor, analyze, and prioritize the
performance of critical applications running on P9500, XP20000 or XP24000 disk arrays.
The logical devices (LDEVs) of an array are mapped to Microprocessor (MP) blades. The I/Os
pertaining to an LDEV are processed by the MP blades associated with it. It is likely that a set of busy
LDEVs are owned by one MP blade, while other less loaded LDEVs are owned by a different MP
Blade. This may result in an uneven load distribution on MP blades. To achieve effective MP blade
utilization and I/O performance, there is also a need to balance the MP blade utilization of P9500
disk arrays.
P9000 Application Performance Extender supports MP blade resource load balancing through the
Dynamic LDEV Ownership Management (DLOM) feature. P9000 Application Performance Extender
monitors the load of MP blades and dynamically changes LDEV ownership in order to balance I/O
workloads across multiple MP blades.
XP and P9500 disk array resources can be prioritized by application and time, so high-priority host
traffic experiences the best performance always.
P9000 Application Performance Extender is supported on HP-UX, Windows, and Linux hosts connected
to XP and P9500 disk arrays in a SAN.
P9000 Application Performance Extender has the following components:
• Communication agent — Is a resident agent software that runs on all the hosts in a SAN environ-
ment. The communication agent discovers hosts, and communicates commands and information
between the host and the management station.
• Controller — Is a software that allocates resources to application groups (HP-UX), and hosts
(Windows, Linux). It helps applications achieve their Service Level Objectives (SLO). It also helps
balance the MP blade utilization of P9500 disk arrays. The controller communicates with the XP
and P9500 disk arrays through the command device.
• Management station — Is a software that communicates and coordinates between the graphical
user interface, the communication agent, and the controller. The management station also maintains
a database of all the XP Application Performance Extender settings and parameters.
With P9000 Application Performance Extender, you can:
• Achieve SLO targets of mission critical applications
• Dynamically change SLO targets based on real time resource requirements of your mission critical
applications
• Service peak load SLOs of critical applications without additional hardware investments
• Add more applications to the XP and P9500 disk arrays without penalizing the performance of
mission critical applications
• Get notified immediately about performance drops
HP StorageWorks P9000 Application Performance Extender Software User Guide 11
• Dynamically balance the MP blade utilization of P9500 disk arrays
Functional representation
Figure 1 shows the working of P9000 Application Performance Extender in a SAN environment.

.
P9000 Application Performance Extender is typically deployed in a LAN/SAN environment. The
management station is deployed in a LAN set up, while the communication agent and the controller
can have both LAN and SAN connectivity.
Management station— The management station is installed on a Windows host and is connected to
the communication agent and the controller through LAN.
Communication agent— The communication agent is installed on all the hosts (HP-UX, Linux, and
Windows). The hosts are connected to the management station through LAN. Hosts use SAN to connect
to the P9500 arrays though the Fibre Channel HBAs.
Controller— The controller is installed on an HP-UX, Linux, or Windows host that is connected to the
P9500 disk array.

3 Licensing P9500 disk arrays
IMPORTANT:
Licensing is applicable only for P9500 disk arrays.
P9000 Application Performance Extender follows a band-based pricing structure. For a new purchase,
you buy the base license and then purchase all the capacity licenses from the capacity band that
matches the total capacity required.
For an upgrade purchase, first verify how much capacity is already installed. Then, add to it the
amount of capacity you intend to purchase. Further, locate the capacity band that contains the sum
you just calculated and purchase all of the desired upgrade license capacity from this band. P9000
Application Performance Extender is licensed on USABLE capacity for P9500 disk arrays and on
RAW capacity for XP disk arrays.
P9000 Application Performance Extender requires a valid license key for each P9500 disk array. If
an array does not have a valid license key, P9000 Application Performance Extender functionality
is disabled for that array.
The usable capacity is calculated as the sum of the following: Total allocated LDEV capacity + total
unallocated LDEV capacity + reserved capacity.
• Total allocated LDEV capacity includes the allocated internal LDEVs
• Total unallocated LDEV capacity includes the unallocated internal LDEVs
• Reserved capacity includes the pool volumes, such as thin provisioning, snapshot, and continuous
access journal volumes
So, usable capacity = Internal LDEVs — (External Volumes + Virtual Volumes)
You can generate a frame license of type, Permanent at the Hewlett-Packard Authorization Center
(HPAC) license key website, using the following URL: http://webkey.external.hp.com. The license
can be generated for a specified usable capacity of your choice, and for an unlimited duration. Each
permanent license is perpetual and unique to a P9500 disk array. After generating a license for a
P9500 disk array, the P9000 Application Performance Extender LTU and the registration number are
bound to the following:
• The P9500 disk array serial number
• The P9000 disk array type
• The usable capacity for which the license is generated
IMPORTANT:
• It is mandatory that you have the P9000 Application Performance Extender registration number
to generate a permanent frame license. This registration number is included in the product entitlement certificate that is provided with every P9000 Application Performance Extender License To
USE (LTU) purchased. For more information on generating licenses, see “Generating licenses at
the HPAC license key website” on page 39.
HP StorageWorks P9000 Application Performance Extender Software User Guide 27
P9000 Application Performance Extender supports the following license types:
• Instant-on license
• Permanent license
• Meter based term (MBT) license

• It is either valid for a period of 120 days from the day you install P9000 Application Performance
Extender or until the time you generate, and install a new license for one or more P9500 disk arrays.
It cannot be generated from the HPAC license key website.
Consider the following example, where P9000 Application Performance Extender is installed on
20th Aug’10 and is controlling a P9500 disk array. The Instant-on license is enabled on the same
date and valid until the 19th Dec’10. If you add one more P9500 disk array on 31st Aug’10, it
is still controlled in the current Instant-on license mode only. The Instant-on duration of 120 days
is not calculated separately for the additional P9500 disk array.
• It is applicable across all the P9500 disk arrays that are controlled by the current instance of
P9000 Application Performance Extender. It is not bound to a specific P9500 disk array. During
the Instant-on license period, P9000 Application Performance Extender can monitor usable capacities of multiple P9500 disk arrays. You can perform all tasks that P9000 Application Performance
Extender supports.
• When the instant-on period expires and a valid license is not yet installed, P9000 Application
Performance Extender switches over to the grace period of 60 days for that P9500 disk array.
Instant-on license activation
P9000 Application Performance Extender indicates that the instant-on license is activated by displaying
the following status message on the License screen:
The P9000 Application Performance Extender trial license expire on month,
day, year. Please contact your HP Representative to purchase the requisite
P9000 Application Performance Extender licenses to avoid disruption of
the P9000 Application Performance Extender services.
Where, month, day, and year is calculated as 120 days from the date when you install P9000
Application Performance Extender.
Every day, a status message on the number of remaining Instant-on days is displayed under Comments
in the List of existing licenses section against each P9500 disk array record for which a permanent
license is not yet installed.
Instant-on license expiration
The Instant-on license expires when one of the following conditions are met:
• The Instant-on license period of 120 days is over and permanent license is not yet installed for
any of the controlled P9500 disk arrays, P9000 Application Performance Extender does the following:
• It initiates a grace period of 60 days for all the P9500 disk arrays. During the grace period,
you can monitor the usable capacities of multiple P9500 disk arrays. You can also perform
all the P9000 Application Performance Extender related operations on P9500 disk arrays.
After the grace period expires, P9000 Application Performance Extender will stop controlling
the P9500 disk arrays, for which permanent licenses are not installed.

Contact your HP representative to procure the additional licenses.
Proactive License Tracking
Proactive license tracking automatically intimates you about the expiration of license(s) for P9500
array(s) monitored by APEX. The notification is done by sending an e-mail from the APEX software to
the user configured e-mail id against the corresponding array. The e-mail is sent three days prior to
the start of the grace period. The e-mail notifies you about the expiry of the license and to install the
license as soon as possible. However, the e-mail cannot be sent in advance in some particular cases
as the grace period cannot be identified in advance. This may happen if the array capacity exceeds
the license capacity. In such cases, the e-mail is sent when the grace period starts.
Figure 3 Proactive License Tracking
.
HP StorageWorks P9000 Application Performance Extender Software User Guide 31
Figure 3 shows the proactive license tracking screen. Data collection discovers all the P9500 arrays
which need to be monitored. You have to select a particular array and enter the notification e-mail
id in the License Settings screen before adding any new valid license. Once the grace period starts,
the notification mails are sent depending on the notification interval set in the settings.ini file.
Permanent License
Permanent licenses are primary licenses that you generate and install on P9000 Application
Performance Extender to control a P9500 disk array. Permanent licenses are for an unlimited duration,
perpetual, and unique to a P9500 disk array. After generating a license for a P9500 disk array, the
P9000 Application Performance Extender LTU and the registration number are bound to the following:
• The P9500 disk array serial number
• The P9500 disk array type
• The usable capacity for which the license is generated
After installing a Permanent license, if you increase the usable capacity beyond the Permanent licensed
capacity, the existing Permanent license cannot be used. P9000 Application Performance Extender
considers it as a license capacity violation and initiates a grace period of 60 days for that P9500
disk array. To end the grace period:
For a P9500 disk array, you can generate and install one of the following based on your requirement:
• A Permanent license.
• A Meter based Term license, which is a secondary license that works only if a Permanent license
is already installed. For more information, see “Meter Based Term license” on page 32
IMPORTANT:
• It is mandatory that you have the P9500 Application Performance Extender registration number
to generate a permanent frame license. This registration number is included in the product entitlement certificate that is provided with every P9000 Application Performance Extender License To
USE (LTU) purchased.
• The unlimited frame license concept is not applicable for the P9500 disk arrays. You must purchase
the additional licenses if you increase the usable capacity, so that P9000 Application Performance
Extender can continue controlling those arrays. For example, if you increase the usable capacity
on a P9500 disk array from 50 TB to 70 TB, you must purchase licenses for P9000 Application
Performance Extender to monitor the additional usable capacity of 20 TB.
Meter Based Term license
Meter based Term licenses are secondary licenses that you generate at the HPAC website and install
as add-on licenses on P9000 Application Performance Extender. Meter based Term licenses cannot
work independently and always need to be installed on a Permanent license. They are not a
replacement to the Permanent license.
A Meter based Term license is generated in TB-Days for the usable capacity that you want to monitor
and the duration for which you want to control. To calculate the total TB-Days of Meter based Term
license that you require, use the following formula:
(Usable capacity - aggregate permanent license) * Duration (number of
days)= TB-Days Meter based Term license
Licensing P9500 disk arrays32
IMPORTANT:
• Additional usable capacity refers to the usable capacity that is beyond the Permanent licensed
capacity.
• A Meter based Term license cannot be installed on multiple management stations.
• Multiple Meter based Term licenses can be generated and installed on a management station. In
such cases, the licenses are used successively.
Meter based Term license requirement
Meter based Term licenses are useful when you want additional usable capacity for a defined duration
or when there is an unplanned surge in the usable capacity that might subsequently reduce. For steady
state license requirements, use Permanent licenses. For dynamic license requirements arising out of
varying business needs, use appropriate TB-Days of Meter based Term license.
IMPORTANT:
For the installed TB-Days to function properly, you must install a minimum of 1TB Permanent license.
The following image illustrates the above mentioned cases.
Example scenario 1
Consider that a small-sized company books air tickets online for its customers. The company has one
P9000 disk array of 75TB usable capacity. A Permanent license is installed on 01/01/2010 to
monitor the 75TB usable capacity. Based on the heavy online booking trend during December'09 January'10 time frame due to Christmas and New Year celebrations, the company is expecting a
surge in the online booking traffic beginning December'10 and continuing till the end of 1st week of
January'11. The company is confident that at least 50TB additional usable capacity is required during
this time frame (estimated 39 days).
In such cases, the company has two options:
• Generate and install a Meter based Term license, as the 50TB spike in usable capacity is for a
limited duration.
• Generate and install a Permanent license for the 50TB usable capacity.
Because the 50TB usable capacity is required for a short duration, it is economical to install TB-Days
of Meter based Term license. If a Permanent license is installed for the 50TB usable capacity, it is
HP StorageWorks P9000 Application Performance Extender Software User Guide 33
used only till the first week of January'11, after which it remains unused until the 75TB current usable
capacity increases by 50TB, and is constantly used.
Following is the suggested Meter based Term license configuration:
Generate 1950TB-Days of Meter based Term license to monitor 50TB additional usable capacity for
39 days. The 1950TB-Days are derived based on the following calculation:
50TB * 39 days = 1950TB-Days of Meter based Term license
The following figure illustrates the scenario described.
So, 50TB usable capacity is monitored every day beginning December'10 for the next 39 days. After
the spike in usable capacity reduces to 75TB, P9000 Application Performance Extender uses the
existing Permanent license that is already installed. So, the company has managed the short duration
spike in usable capacity with Meter based Term license and also retained the Permanent license to
monitor the existing 75TB usable capacity.
Example scenario 2
Consider the scenario of another company that has to use P9000 Application Performance Extender
to monitor a P9500 disk array (5TB usable capacity) for a duration of only 180 days. It is a one-time
activity for a specific project. As it is a time bound project, Meter based Term licenses are
recommended. Following is the suggested configuration:
1. Generate and install 1TB Permanent license.
Out of the 5TB usable capacity, 1TB is managed by the Permanent license.
2. Generate and install 720TB-Days Meter based Term license to monitor the additional 4TB usable
capacity for 180 days.
4TB * 180 days = 720TB-Days Meter based Term license
Meter based Term license activation and consumption
Similar to a Permanent license, a Meter based Term license is also bound to the disk array serial
number and the usable capacity for which the license is generated. Once installed, you can use the
TB-Days to monitor the additional usable capacity based on your requirement. For example, if 90
TB-Days Meter based Term license are installed, you can use the 90TB-Days in any of the following
ways:
• 90TB-Days to monitor 90TB additional usable capacity in one day.
• 90TB-Days to monitor 1TB additional usable capacity for 90 days.
• 90TB-Days to monitor 10TB additional usable capacity for nine days.
• Any usage where the duration (Y days) multiplied by the additional usable capacity (XTB) equals
90TB-Days.
Licensing P9500 disk arrays34
The following figure illustrates the use of Meter based Term license.
At the time of installing the Meter based Term license, if the usable capacity is within the Permanent
licensed capacity, the installed TB-Days remain dormant till the usable capacity exceeds the Permanent
licensed capacity. They are activated only after the Permanent license is completely used. The TB-Days
are used for the duration when the usable capacity exceeds the installed Permanent licensed capacity
and the exceeded capacity can be managed by the installed TB-Days.
NOTE:
• After the installed TB-Days are activated, P9000 Application Performance Extender verifies the
remaining TB-Days every day after 1:00 PM and accordingly updates the TB-Days status on the
License screen - List of existing licenses section. For more information on the License screen, see
“License screen” on page 28.
• If the installed TB-Days are used in the first half of a day, the TB-Days status is updated after
1:00 PM on the same day.
• If the installed TB-Days are used in the second half of a day, the TB-Days status is updated
after 1:00 PM on the next day.
• An installed Meter based Term license cannot be removed.
For example, a Permanent license is installed on 11/30/2010 to monitor 50TB usable capacity. In
addition, 90TB-Days are also installed on the same day to monitor 10TB additional usable capacity
later for nine days. As the usable capacity is still within the Permanent licensed capacity, P9000
Application Performance Extender does not use the 90TB-Days. The following table lists the fields that
are updated on the License screen - List of existing licenses section when the 90TB-Days are installed
for a P9500 disk array record.

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 Application Performance
Extender uses 10TB-Days, and updates the following fields after 1:00 PM on the same day.

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 Application Performance Extender 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 Application Performance Extender enters 60 days grace period for that particular P9500 disk
array:
• A Permanent or appropriate TB-Days of Meter based Term license installed to control the additional
usable capacity.
• The additional usable capacity reduced to match the Permanent licensed capacity.
In addition, P9000 Application Performance Extender 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 controlled. After 60 days,
a capacity violation is reported and P9000 Application Performance Extender stops controlling that
disk array.
Licensing P9500 disk arrays36
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

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.
HP StorageWorks P9000 Application Performance Extender Software User Guide 37
4. As the usable capacity is beyond the Permanent licensed capacity, P9000 Application Performance
Extender enters 60 days grace period on 11/30/2010.
5. 1000TB-Days Meter based Term license are installed on 12/02/2010.
The following fields in the License screen – List of existing licenses section display:
• License Capacity: 50TB, +1000TB-Days
• License Status: Installed
• Term (Days): N/A
• End Date: Never
After 1:00 PM, the above fields are updated to display:
• License Capacity: 50TB, +1000TB-Days
• License Status: Installed
• Term (Days): 10
• End Date: 12/11/2010
6. If 90.5TB is monitored on the same day, P9000 Application Performance Extender considers
91TB-Days and again updates the following fields to reflect the latest data, which is as follows:
• License Capacity: 50TB, +909TB-Days
• License Status: Installed
• 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, P9000 Application Performance Extender 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, P9000 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:
Licensing P9500 disk arrays38
1. A P9500 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, P9000 uses the 5TBDays completely by 12/04/2010.
If the additional usable capacity equivalent to more than 1TB-Days is consumed a day, the 5TBDays 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. A P9500 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.
4. If the usable capacity rises beyond the 25TB Permanent licensed capacity on 11/30/2010 and
3.5TB is used on the same day, P9000 Application Performance Extender considers 4TB-Days.
5. If there has been no activity from 11/30/2010 till 12/28/2010, the remaining 8TB-Days are
not used.
6. If 4TB is used on 12/29/2010 followed by another 4TB on 12/30/2010, P9000 considers
4TB-Days on each day, and the 8TB-Days are completely used by 12/30/2010.
So, the TB-Days are used only when the additional usable capacity must be monitored.

Exceeding Permanent licensed capacity and grace period
When the usable capacity of a P9500 disk array exceeds the Permanent licensed capacity, P9000
Application Performance Extender switches to the grace period of 60 days for that particular disk
array.
The License Status for such P9500 disk arrays displays Capacity Insufficient in the View License Details
section.
To continue monitoring the usable capacity, you can generate a Permanent license or appropriate
TB-Days of Meter based Term license based on your requirement.
Example scenario 7
Consider the following points:
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. Due to a surge in storage requests, another 25TB usable capacity is added on 11/30/2010 for
a duration of five days.
4. As the additional usable capacity is greater than the Permanent licensed capacity, P9000 Ap-
plication Performance Extender enters 60 days grace period.
Because this is a short term unplanned surge in storage requests, you can install TB-Days of Meter
based Term license to monitor the additional usable capacity for the specified duration. To monitor
25TB for five days (at the rate of 25TB a day), generate and install 125TB-Days on 11/30/2010.
As 125TB-Days are sufficient for five days, P9000 Application Performance Extender ends the grace
period and updates the following fields in the License screen – List of existing licenses section:
• After installation on 11/30/2010:
• License Capacity: 50TB, +125TB-Days
HP StorageWorks P9000 Application Performance Extender Software User Guide 41
• License Status: Installed
• Term (Days): N/A
• End Date: Never
• After 1:00 PM on 11/30/2010:
• License Capacity: 50TB, +100TB-Days
Consider that 25TB-Days are used after installation.
• License Status: Installed
• Term (Days): 4
• End Date: 12/04/2010
If the remaining 100TB-Days are completely used in the first half of 12/04/2010 and any of the
following is not done:
• The usable capacity is reduced to within the Permanent licensed capacity limit
• Extra TB-Days installed to monitor the 25TB usable capacity
• Another Permanent license installed to monitor the 25TB usable capacity
As a result, P9000 Application Performance Extender again enters 60 days grace period after 1:00
PM on the same day and 0TB-Days are available. In addition, it begins reducing (negative count) the
installed TB-Days by 25TB and updates the following fields in the License screen daily.
After 1:00 PM on 12/04/2010:
• License Capacity: 50TB, 0TB-Days
• License Status: Capacity Insufficient
• Term (Days): 0
• End Date: Expired
If 100TB-Days are completely used in the second half of 12/04/2010, 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 12/05/2010. In this case, the License Capacity shows 50TB,
–25TB-Days on 12/05/2010.
Exceeding Meter based Term licensed capacity and grace period
When the existing TB-Days are not sufficient to monitor the additional usable capacity, P9000
Application Performance Extender considers it as a capacity violation and enters a grace period of
60 days. During the grace period, P9000 Application Performance Extender begins reducing the
installed TB-Days. Within 60 days, if a Permanent license is installed, P9000 Application Performance
Extender stops reducing the TB-Days and ends the grace period for that particular P9500 disk array.
If appropriate TB-Days are installed, P9000 Application Performance Extender uses part of the units
to nullify the negative count and the rest of the units to end the grace period.
The every day reduction in TB-Days is equal to the additional usable capacity because of which the
grace period has started.
Licensing P9500 disk arrays42
NOTE:
Reduction or negative counting is only applicable for the installed TB-Days. It is not applicable for
Permanent licenses.
After 60 days grace period, P9000 Application Performance Extender stops controlling the P9500
disk array.
Example scenario 8
Consider the following points:
1. A P9500 disk array has a usable capacity of 50TB.
2. A Permanent license is installed on 11/23/2010 to monitor the 50TB usable capacity.
3. Due to a surge in storage requests around 11/30/2010, another 10TB usable capacity is added
for a duration of five days.
4. Because this is a short term unplanned request, it is addressed by installing 50TB-Days of Meter
based Term license on 11/30/2010.
5. After the installed TB-Days are consumed by 12/04/2010 and extra TB-Days are not added to
monitor the 10TB usable capacity, P9000 Application Performance Extender does the following:
a. Enters the grace period after 1:00 PM on 12/04/2010 and 0TB-Days are available. The
following fields are updated with the latest TB-Days data:
• License Capacity: Displays 50TB, 0TB-Days
• License Status: Capacity Insufficient
• Term (Days): 0
• End Date: Expired
b. Begins reducing the installed TB-Days by 10TB every day starting from 12/05/2010:
• On 12/05/2010, 0TB-Days are reduced to –10TB-Days
• On 12/06/2010, –10TB-Days are reduced to –20TB-Days
• On 12/06/2010, –20TB-Days are reduced to –30TB-Days
• On 12/07/2010, –30TB-Days are reduced to –40TB-Days
• On 12/08/2010, –40TB-Days are reduced to –50TB-Days
• On 12/09/2010, –50TB-Days are reduced to –60TB-Days
6. The reduction in TB-Days continues till you install the appropriate TB-Days, so that P9000 Applic-
ation Performance Extender does the following:
• Shows positive TB-Days
• Ends the grace period for that particular P9500 disk array
7. So, if you want to install TB-Days on 12/09/2010 for a duration of five days, generate 110TB-
Days of Meter based Term license. Out of the 110TB-Days:
• 60TB-Days (6 days * 10TB) are used to nullify the reduction in installed TB-Days.
• 50TB-Days (5 days * 10TB) is required for P9000 Application Performance Extender to con-
tinue monitoring the 10TB usable capacity for another five days.
With 110TB-Days, P9000 Application Performance Extender ends the grace period and continues
to monitor the 10TB usable capacity for another five days.
When fractions of a TB of additional usable capacity is monitored and the installed TB-Days are not
sufficient, P9000 Application Performance Extender considers it as a capacity violation and enters a
HP StorageWorks P9000 Application Performance Extender Software User Guide 43
grace period of 60 days. In such a case, if you install the appropriate TB-Days, P9000 Application
Performance Extender ends the grace period for that particular P9500 disk array.
Example scenario 8
Consider the following points:
1. A P9500 disk array has a usable capacity of 75TB.
2. A Permanent license is installed on 11/24/2010 to monitor the 75TB usable capacity.
3. Due to a surge in storage requests around 11/30/2010, another 20TB usable capacity is added
for a duration of five days.
4. Because this is a short term unplanned request, it is addressed by installing 100TB-Days of Meter
based Term license on 11/30/2010.
5. As the usable capacity is beyond the Permanent licensed capacity, P9000 Application Performance
Extender uses the 100TB-Days of Meter based Term license.
Based on the usable capacity consumed, P9000 Application Performance Extender 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, P9000 Application Per-
formance Extender 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 P9000 Application Performance Extender does the following:
• Shows positive TB-Days
• Ends the grace period for the particular P9500 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 P9000 Application Performance Extender to
continue monitoring the 20TB usable capacity for another five days.
With 160TB-Days, P9000 Application Performance Extender ends the grace period and continues
to monitor the 20TB usable capacity for another five days.
Licensing P9500 disk arrays44
Violating licensed capacity
After 60 days of grace period, P9000 Application Performance Extender considers it as a capacity
violation and stops controlling the P9500 disk array. However, it continues to monitor the workload
performance and MP blade utilization.
During a capacity violation phase, if you do one of the following:
• Install a Permanent license or appropriate TB-Days of Meter based Term license for P9000 Applic-
ation Performance Extender to control the P9500 disk array.
• Reduce the usable capacity of the P9500 disk array to match the Permanent licensed capacity.
P9000 Application Performance Extender verifies the usable capacity of the P9500 disk array. If
it is less or equal to the licensed capacity, the existing capacity violation is removed.

Specifying DLOM settings
P9000 Application Performance Extender provides an option to balance the MP blade utilization of
P9500 disk arrays. The Dynamic LDEV Ownership Management (DLOM) feature enables load
balancing of P9500 disk arrays by dynamically changing LDEV ownership and balancing I/O
workloads across multiple MP blades. The I/Os pertaining to an LDEV are processed by the MP blade
associated with it. P9000 Application Performance Extender will collect, monitor, and maintain the
overall MP blade utilization data. When the load balancing option is enabled, and if there is a
considerable difference in the MP blade utilizations, the LDEVs from the busier MP blades are moved
to less busy MP blades. For more information on enabling DLOM, see Enabling DLOM settings.

Enabling DLOM settings
There are three different modes to enable DLOM:
• DLOM only mode (Non QoS MPBs) — In this mode, P9000 Application Performance Extender
operates as a load balancer, where MP blade utilization for I/O processing is balanced by
changing LDEV ownership across multiple MP blades. This reduces load on overloaded MP blades.
• QoS-DLOM mode (QoS MPBs) — In this mode, you prioritize the performance of critical applications
and achieve the defined SLO targets, while P9000 Application Performance Extender operates
as a load balancer to reduce load on overloaded MP blades.
• Partial-QoS-DLOM mode — In this mode, P9000 Application Performance Extender operates as
a load balancer, while you can prioritize the performance of applications only on a selected set
of MP blades.
NOTE:
In Partial mode, ensure that the applications where I/O prioritization is required are running on
LDEVs owned by the MP blades present in the QoS MPB compartment. For more information on
changing LDEV ownership, see Appendix E
If there are no MP blades present in the Non QoS MPBs compartment, the mode is QoS-DLOM. If
there are no MP blades in the QoS MPBs compartment, the mode is DLOM only.
You can move MP blades from the Non QoS MPBs compartment to the QoS MPBs compartment and
vice versa. For the change to be effective, ensure that you click Submit.
Load balancing only
The amount of I/Os that are generated by applications are dynamic. This will lead to an imbalance
in MP blade utilization.
If you add or remove applications generating I/Os frequently, there is a need to balance MP blade
utilization.
NOTE:
You can use the load balancing feature of P9000 Application Performance Extender even if the
applications generating I/Os are hosted on platforms or operating systems where P9000 Application
Performance Extender I/O prioritization is not supported.
1. Select the array.
2. Ensure that all the MP blades are in the Non QoS MPBs compartment.
3. Click Submit.
4. Select the Non QoS MPBs Load balancer check box.

Managing workloads
P9000 Application Performance Extender enables you to add workloads and assign priorities based
on the defined SLO profiles assigned to XP or P9500 disk arrays. A workload is a combination of
I/Os from a host (Windows or Linux) and I/Os from a PRM group in a host (HP-UX).
P9000 Application Performance Extender supports application level performance differentiation across
applications on HP-UX hosts, and host level performance differentiation across hosts running
applications on Windows and Linux hosts.
In HP-UX, using PRM, you can create PRM groups and assign IDs (PRM IDs) to uniquely identify a
PRM group. P9000 Application Performance Extender workloads map to PRM groups.

Specifying workload settings in a cluster environment
P9000 Application Performance Extender is not cluster aware, but it can work with both Active-Active
and Active-Standby clusters.
Active-Active (multinode) application in a cluster configuration
You must map all the hosts (Windows and Linux) and PRM groups (HP-UX) corresponding to the
multinode application to the same workload number. This will enable the controller to prioritize the
application depending on the SLO specified for that workload number.
Active-standby (failover) application in a cluster configuration
You must map the active and the standby hosts (Windows, Linux) and PRM groups (HP-UX) to the
same workload number. This will enable the controller to prioritize the application based on the
specified SLO, irrespective of the node that is hosting the application.
NOTE:
The communication agent must be configured on all the cluster nodes and they must point to the same
management station.
