We have several clusters in the PB range that use dmcrypt.  I can't speak to what it's performance detriment is to a non-dmcrypt cluster, but our clusters run just fine.  I don't really understand the question though... Either you need dmcrypt for legal reasons in your business or you don't.  If you don't then why use it?

Assuming I am understanding the question...

If there isn't too big a performance hit, it makes disk disposal (we expect disks to die, right?) much simpler.
