Does ARS support / work under DARE (Data At Rest encryption) and has anyone implemented this / advice?

We are mandated to implement DARE which is encryption of data/bits on hard drives and in databases like SQL  and Oracle.
Previously, we enabled SQL connection encryption as described in this ARS SQL ENCRYPTION link.  This question refers specifically to the data sitting in the databases used by ARS.

any support, experience, prior nibbles on this topic?
