Data-at-Rest Encryption
The
Data-at-Rest
page allows you to enable Data-at-Rest Encryption on
the DXi8500 and manage security keys.
Data-at-Rest Encryption uses Self Encrypting Drive (SED) technology to
secure all data stored on the DXi8500. This includes file data and
metadata, configuration files, and the DXi software and operating
system. When Data-at-Rest Encryption is enabled, all hard drives in the
DXi are paired with the disk controllers using encryption keys. After this,
accessing data on the drives requires the same encryption keys and
controllers that were used to write the data. This ensures that a drive
that is physically removed from the DXi cannot be read using another
system or device.
To enable Data-at-Rest Encryption, the feature must be licensed, and all
of the drive controllers and hard drives (active and hot spares) in the DXi
must support Self Encrypting Drive (SED) technology (not available in all
regions). A DXi8500 configuration with all 3TB SED hard drives meets
the requirements for Data-at-Rest Encryption.
