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 (fixed 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 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.
Database Protection
The IBM Database Protection feature provides the highest level of protection for
Oracle databases by detecting corrupted Oracle data and preventing it from being
processed to storage.
The IBM Database Protection feature complies with the Oracle Hardware Assisted
Resilient Data (HARD) initiative, which provides an end-to-end data protection
between an Oracle database and permanent storage devices.
Data must pass through many software and hardware layers on its way to storage.
It is possible for the data to become corrupted, on a rare occasion, caused by a
malfunction in an intermediate layer. With the IBM Database Protection feature, an
IBM DS8000 model can validate whether Oracle data blocks are consistent using
the same logic that Oracle uses. This validation is done before the write request is
processed. You can designate how the transaction is managed: either rejected and
reported, or processed and reported.
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:
v Easy Tier: automatic mode
v Easy Tier: manual mode
The feature enables the following functions for the storage type:
v Easy Tier application
v Easy Tier heat map transfer
v The capability to migrate volumes for logical volumes
