How can I tell if my hard drives have a battery backed write cache (BBWC)?

How can I tell if it is enabled and/or configured correctly?

I don't have physical access to my server. It's a GNU/Linux box.

I can provide supplemental incremental information/details as requested. My frame of reference is that of a DBA -- I have access and privileges, but (usually) only tread where I know am supposed to. :)
