Using OBDR in ML110G3 with SATA-RAID-1

Dear all :

I got a ML110G3 server which had a SATA RAID-1
as storage-disks...

I knew there is an ODBR by using USB TAPE for this server...
but I saw that OBDR was booted as a SCSI-CD-ROM to do the restore
but is that also worked in SATA-RAID-1 or just the SCSI-model is worked ??

I am planning to but a USB TAPE to do OBDR but need to know if that worked with my current G3 server....
