| There is no such limit in ADSM.  As you note, the dsmc process doesn't

I concurr with this.  SunSITE UNC-CH has filesystems as large as 13GB (Sun
1000) comprised mostly of small files.  It gets a bit ugly.  But dsmc
gets the job done on a daily basis.  When dsmc hits a new large filesystem
during its processing, you should see a significant amount of CPU time as
it traverses the inode table of that filesystem.
