Managing Secure Data
Secure Data provides data-at-rest encryption with key management for self-encrypting drives (SED). The Self-Encrypting Drives feature
must be licensed to use Secure Data.
How Secure Data Works
Using Secure Data to manage SEDs requires an external key management server. If a key management server has not been congured or is
unavailable, Storage Center allows SEDs to be managed; however, it will not secure the SEDs until the key management server is available
and congured, at which point they will be secured.
NOTE
: Create a backup for the key management server before removing an SED and after managing an SED.
Each FIPS disk in Storage Center has an internal Media Encryption Key (MEK). The key resides on the disk, providing encryption for data
written to the disk and decryption for data as it is read from the disk. Destroying the key makes any data on the disk immediately and
permanently unreadable, a process referred to as a crypto erase. When you add an SED to, or release an SED from a Secure Data folder,
the MEK is destroyed and a new key is generated. Creating a new key allows the disk to be reused, although all previous data is lost.
WARNING
: Managing a FIPS SED and assigning it to a Secure Data folder destroys the encryption key on the disk, which makes
any previous data on the disk unreadable.
