CentOS - Mar 2009 - LSI Logic MegaRAID 8480 Storage controller policies?

Life is much better now that I'm using -h instead of the manual.

I have a new question about policies

Direct   and DisDskCache makes sense
Cached and EnDiskCache makes sense

not so sure about

Direct    and EnDskCache
Cached and DisDsk Cache

Do they make sense?

I believe Cached|Direct refers to adapter based caching of the logical
(virtual) disk whereas EnDskCache|DisDskCache refers to physical disk
cache.

The adapter can hold data in the event of a powerloss with a BBU
but I can't see how the disc could.
