Licensed functions

Edit online

Licensed functions are the operating system and functions of the storage system. Required features and optional features are included.

IBM® authorization for licensed functions is purchased as 5341 or 9031 machine function authorizations. However, the license functions are storage models. For example, the Base Function license is listed as a 5341 or 9031 model FFA. The 5341 or 9031 machine function authorization features are for billing purposes only.

The following licensed functions are available:

Base Function: The Base Function license is required for each storage system.
z-synergy Services: The z-synergy Services include z/OS® licensed features that are supported on the storage system.
Copy Services: Copy Services features help you implement storage solutions to keep your business running 24 hours a day, 7 days a week by providing data duplication, data migration, and disaster recovery functions.
Transparent Cloud Tiering: Transparent Cloud Tiering (TCT) license provides a native cloud storage tier for IBM® Z environments. Transparent cloud tiering moves data directly from the storage system to cloud object storage, without sending data through the host.
