Self-Encrypting FMD (SE-FMD) delivers greater security along with the performance and compression capabilities that XP7 FMDs are known for. The SE-FMD will always encrypt data when installed, it can't be turned off. Unlike competitive offerings, XP7 self-encrypting FMDs can be co-located in the same array with non-encrypting devices, as long as the SE-FMDs are in a separate disk group.
