Explanation/Reference:
D@RE is included by default on Unity arrays and included in the Unity license file unless otherwise
requested during ordering. Therefore, all that is needed to activate D@RE is to install the D@RE enabled
license file. The license installation process is not specific to D@RE, and is required to be performed
before using the array. When logging into Unisphere for the first time, license installation appears as a step
of the Unisphere Configuration Wizard, prompting the administrator to install the license file obtained from
EMC. If this license file includes D@RE functionality, D@RE will be enabled once the license file is
installed successfully
Note: Unity storage systems address sensitive data concerns through controller-based Data at Rest
Encryption (D@RE), which encrypts stored data as it is written to disk.
D@RE is a license controlled feature available by default on Unity storage systems, and, being designed
to be largely invisible to administrative end users, requires almost no effort to enable or manage. Enabling
the feature or backing up the encryption keys externally takes just seconds, and redundant keystore
backups stored on array ensure that user data is always as available as it is secure.
