Generally speaking --> you use a SATA drive in a SAS expander at your own risk.  I used to be at Nexenta, and they would not support customers who deployed SATA drives on SAS expanders.  These days, the price delta between SAS and SATA (for enterprise) is small enough to be worth it for the headaches you avoid.
