Dell PowerVault ML6000 SSS
How does EKM handle the addition of new drives or the replacement
of bad drive?
New or replacement drives can be added to the EKM through auto discovery
or manually. To auto discover the drives, check the auto discovery checkbox
on the EKM Server Configuration tab in the EKM GUI. To add the drives
manually, follow the instructions in the Encryption Key Manager User's Guide
to add the drives through the command line interface.
It is recommended to use auto discovery as the 12-digit drive serial number
(10 digit serial number plus two leading zeros) must be entered to add the drive
manually. If security is a concern, auto discovery can be turned on and test
backups run to add the necessary drives to the drive table. Then auto discovery
can be turned off to prevent new drives from obtaining keys.
As long as EKM can authenticate the drive digital signature assigned to the
drive at the factory, EKM accepts the key request. The keys are grouped in the
key store in key groups and the key groups can be associated with the
new/replacement drives after the drives are added.
How does EKM handle the addition of a new library or the replacement
of a bad library?
In library-managed encryption, the library is only a proxy. Libraries can be
added or replaced and keys provided as long as the EKM can authenticate to
the digital signature on the drive.

How is compression affected by encryption and vice versa?

The data is compressed prior to being encrypted as encrypted data is
generally uncompressible. Therefore compression has no effect on
encryption and vice versa.

Is there a performance impact with encryption?

There can be a slight performance impact with encryption but it should not
cause an increase in the backup window.
