Base Function license

Edit online

The Base Function license provides essential functions for your storage system. A Base Function license is required for each storage system.

The Base Function license is available for the following license scopes: FB and ALL (both FB and CKD).

  • Encryption Authorization
  • Logical configuration support for FB
  • Space Reclamation (Unmap)
  • Dynamic Volume Expansion
  • FB Compression using FlashCore Modules
  • Local Key Manager for Data at Rest
  • Secure Boot
  • Multifactor Authorization
  • LDAP
  • Easy Tier®
  • Operating Environment License (OEL)
  • Thick/Thin Provisioned Volume support

The Base Function license feature codes are ordered in increments up to a specific capacity. For example, if you require 160 TB of capacity, order 10 of feature code BAA0 (10 TB each up to 100 TB capacity) and 4 of feature code BAA1 (15 TB each, for an extra 60 TB).

The Base Function license includes the following feature codes.

Base Function license rules

The Base Function license authorizes you to use the model configuration at a specific capacity level. The Base Function license must cover the full raw capacity of your storage system, which includes the raw capacity of any expansion frames within the storage system. The license capacity must cover both open systems data (fixed block data) and IBM® Z data (count key data). Copy Services, Transparent Cloud Tiering and z-synergy Services must have a capacity that is equal to or less than the Base Function License.

Note: Your storage system cannot be logically configured until you activate the Base Function license. On activation, drives can be logically configured up to the extent of the Base Function license authorization level.

As you add more drives to your storage system, you must increase the Base Function license authorization level for the storage system by purchasing more license features. Otherwise, you cannot logically configure the additional drives for use.
