The SAS 5/i (which you have) is a NON-RAID controller/HBA.  The SAS 5/iR is the 'R'AID version.  It is used primarily for non-RAID devices, such as tape drives.  If you need RAID, the only option you have is a software/OS-managed RAID (or purchase an actual RAID controller (SAS 5/iR, SAS 6/iR, PERC 5/i, PERC 6/i).
Hello. I have bought a few days ago a Dell server PowerEdge 1950. I have installed Windows 2003 server on it (adding LSI 1068 drivers to detect HDD). The problem: I want to configure RAID 1 (data mirror) and using this ([URL] tutorial at page 27 Figure 3.1 Adapter Properties Screen I don't have RAID Properties. Any ideas what can be a problem? Server has two disks plugged. Bellow I attached DSET full system log and screens from LSI SAS UI (ctrl+c when booting). Thanks a lot for help!
