I used the RES2SV240 card in OI for a while with no issues. It is a standard LSI based LSISAS2x expander chip. Use it now in FreeNAS and the 9211-8i card functions fine with SATA drives. I currently have 20 SATA drives connected to it with no issues while running IT firmware and ZFS.
I have also tried a SATA expansion card and it sucked. There is a big difference between a proper SAS expander like the RES2SV240 and cheap SATA expanders. I have never plugged and expander into an expander though :) This should be possible but I have never had the need to do so.
