The Base Function license includes the following features:
• Encryption Authorization
• Easy Tier
• Operating Environment License (OEL)
• Thin Provisioning
The Base Function license feature codes are ordered in increments up to a specic capacity. For example,
if you require 160 TB of capacity, order 10 of feature code 8151 (10 TB each up to 100 TB capacity) and 4
of feature code 8152 (15 TB each, for an extra 60 TB).
The Base Function license includes the following feature codes.
Table 37. Base Function license feature codes
Feature Code Feature code for licensed function indicator
8151 BF - 10 TB (up to 100 TB capacity)
8152 BF - 15 TB (from 100.1 TB to 250 TB capacity)
8153 BF - 25 TB (from 250.1 TB to 500 TB capacity)
8154 BF - 75 TB (from 500.1 to 1250 TB capacity)
8155 BF - 175 TB (from 1250.1 TB to 3000 TB capacity)
8156 BF - 300 TB (from 3000.1 TB to 6000 TB capacity)
8160 BF - 500 TB (from 6000.1 TB to 12,000 TB capacity)
Base Function license rules
The Base Function license authorizes you to use the model conguration at a specic capacity level. The
Base Function license must cover the full physical capacity of your storage system, which includes the
physical capacity of any expansion frames within the storage system. The license capacity must cover
both open systems data (xed block data) and IBM Z data (count key data). All other licensed functions
must have a capacity that is equal to or less than the Base Function license.
Note: Your storage system cannot be logically congured until you activate the Base Function license. On
activation, drives can be logically congured 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 congure the additional drives for use.
Encryption Authorization
The Encryption Authorization feature provides data encryption by using IBM Full Disk Encryption (FDE)
and key managers, such as IBM Security Key Lifecycle Manager.
The Encryption Authorization feature secures data at rest and offers a simple, cost-effective solution for
securely erasing any disk drive that is being retired or re-purposed (cryptographic erasure). The storage
system uses disks that have FDE encryption hardware and can perform symmetric encryption and
decryption of data at full disk speed with no impact on performance.
IBM Easy Tier
Support for IBM Easy Tier is available with the IBM Easy Tier feature.
The Easy Tier feature enables the following modes:
• Easy Tier: automatic mode
• Easy Tier: manual mode
