I'm a little confused about the methods of enabling hardware encryption on a PERC H800 and H700 in a Dell R610 server. This may relate to LKM (Dell's local key management versus DKM).
After I successfully created the encryption passphrase, the options in the perc controller included an option to "save to DKM" or some similar wording. When I selected the DKM option, the option failed. What is this DKM option? (I was able to lock the virtual drive without this).
Is the optimal configuration for a PERC H800 in a Dell R610 to enable the TPM chip in the computer bios and have the TPM chip interact with the PERC H800 or H700? How do you do this?
We also have an R620 with PERC H710 and H810 cards-- would I take the same approach (DKM) or is Local Key Management (LKM) preferred?
We do have all self-encrypting drives attached to the cards.
