Both of them never have been in the business of putting hard
limits in place.  We currently have a hard limit in place
because the storage for the cdb is allocated statically.  This
is a desin decision done more than ten years ago that we're
slowly trying to fix.  Second we have a facility to allow
LLDDs limit the size of the cdb they receive.  It's not
mandatory in any way, but very useful for those "smart"
HBAs that can't deal with larger dbs due to hardware limitations.
