FAQ’s, continued:

Can we mix RAID sets with some having normal drives and other RAID sets having SEDs?

Yes, you can mix SEDs and non-SEDs but you will not be able to secure those Virtual Disks.

Securing a Virtual Disk requires all disks in the array to support SED.

Controller Security Enabled

Controller Security Disabled

SEDs and Non-SEDs

Secured VD not allowed

What is Secure Erase or Cryptographic Erase?

Secure erase or Cryptographic erase allows you to scramble that data stored on the disk by changing the DEK.

Preforming this erase operation will render that data on the device indecipherable and the data on the drive will not

be able to be recovered. Secure erase or Cryptographic erase can only be done on a drive that is not configured in a

Virtual Disk.

What is FIPS-140-2 level 2 compliance and does DELL EMC have supported drives?

FIPS stands for Federal Information Processing Standards and it is the mandatory standard required to protect

sensitive or valuable data within Federal systems. Dell EMC offers SED drives with and without FIPS-140-2 level 2

certification, but it is not required for PERC secured VDs.
