Will be taking on work that requires encryption of drives when at rest. I have to certify this and it has to be FIPS 140. Very large data files with private information. I will do de-identification and linking of one data set to many data sets using SAS. I can go the route of buying many self-encrypting drives and a controller that deals with them. Or can I consider the Areca 1882 which claims it has controller level hardware encryption function support. Can't use software encryption or any form of encryption that can be compromised when I am not in my office and when system is off. (I also will need to have remote start-up, but that's another thread). I think I can get away with lower cost drives, but compensate with a more robust RAID array (so more than one drive can go bad at a time) if I go with controller level hardware encryption. I noticed LSI logic released a controller level hardware encryption H(ost)BA but it is not (yet) a RAID controller with controller level hardware encryption. I am told I can build a ZFS system with FIPS 140 compliance. Does anyone have experience with building an array with self encrypted drives or use the 1882 with controller level hardware encryption or FIPS 140 ZFS?
