Encryption
FlashSystem 900 storage system provides support for AES-XTS 256 bit data-at-rest encryption when the
Encryption Enablement Pack, feature AF14, is ordered.
In addition, the FlashSystem 900 has the following functions:
Hot Encryption Activation - Adding an encryption license to a previously initialized system
z
Encryption Re-key - Changing the encryption key on a previously initialized system
z
Both of these operations can be done concurrently and do not cause loss of access to data. Both
operations do require that you purchase the Feature Code AF14: Encryption Enablement Pack.
If you are planning to implement either Hot Encryption Activation or Encryption Re-key, inform IBM
support so that they can monitor the operation
Hot Encryption Activation
Hot Key Activation allows an unencrypted FlashSystem to be encryption-enabled while the system is
running, without impacting customer data in any way.
Note: The system requires that at least two copies of the encryption access key are made, for a total of at
least three USB drives containing the key.
