im pretty sure the s300 is actually the ahci ports coming off the motherboard. if its in ahci mode it should Just Work(tm) as a sata controller. not sas, sorry. the h200 was the last straight sas hba you could get in a dell. if you want sas ports in their more recent machines you can configure physical disks on a h330 or h730, both of which are mfii controllers. dlg
