Chapter 10. License activation and management
The management and activation of licensed functions are responsibilities that are associated with the role
of your storage administrator.
Management refers to the use of the IBM Data storage feature activation (DSFA) website (www.ibm.com/
storage/dsfa) to select a license scope and to assign a license value. You can complete these activities
and then activate the function.
Activation refers to the retrieval and installation of the feature activation code into the storage system.
The feature activation code is obtained by using the IBM Data storage feature activation (DSFA) website
(www.ibm.com/storage/dsfa) and is based on the license scope and license value.
You complete these activities at the following times:
• After the technical service representative installs your storage system, and before you congure it.
• When you increase the extent of the function authorization for a licensed function (that is, you add more
capacity to your license).
To complete these activities, access the IBM Data storage feature activation (DSFA) website
(www.ibm.com/storage/dsfa).
When you access the DSFA website, you must enter information about your storage system so the web
application can access the correct function authorization records. You can nd this information either by
clicking Need Help in the Activate Licensed Functions page or by selecting Properties on the System
page of the DS8000 Storage Management GUI.
Planning your licensed functions
As you plan for your licensed functions, it is important to consider increases in your workload
requirements. To provide more flexibility with licensing, use-based licensing is supported on the storage
system.
The Base Function license is based on the entire capacity of the storage system.
The z-synergy Services, Copy Services, and Copy Services Manager on the Hardware Management
Console (HMC) licenses are priced based on the use of license capacity that you purchase.
With the use-based license capability comes the requirement to plan how much storage capacity you
require for future growth. As you plan for your licensed functions, it is important to consider increases in
your workload requirements. For example, consider the following guidelines, which include but are not
limited to:
• Plan for storage space allocation. Determine your typical storage requirements and consider how much
more storage you would need if you have rapid or unpredictable growth.
• Estimate the amount of capacity you need for current and future Copy Services functions. For example,
consider the number of target volumes you need for FlashCopy relationships at remote sites. As the
number of FlashCopy target volumes increase, more available bandwidth of the disk system might be
used by the copy process. In addition, Copy Services solutions that require multiple copies of data can
also require extensive capacity storage.
Recognizing that both your storage and data requirements will increase over time and that capacity and
performance planning is your responsibility, ensure that you purchase and manage your licensed
functions for maximum usage. It can be more cost effective to purchase more storage capacity to ensure
that the maximum usage of your licensed functions does not exceed the allowed capacity of the storage
that was purchased. If the capacity is exceeded, IBM is notied that the usage exceeds the allowed
capacity on any given licensed function. You are notied by IBM and required to extend enablement of
your licensed function and install a new licensed feature key.
