The earlier (2008) Opensolaris drivers tended to crash the server if you pulled out an active drive. It may have improved in later releases. In the case of the Sun Storage Appliances, the sata (and sas) drivers used are different from those in Opensolaris and are considerably better featured.
My understanding is the chipset on the sata cards can't handle drive events as well as sas controllers do. After testing of both options, I concluded that sas was the better choice because of this, cabling complexity (24 bay chassis isn't fun), and expandability. The controller and backplane price difference diminishes when you get to 24 bays.
