Initially wheneveer I see RAID 1+0 or 0+1, I think it should have at least 4 drives:
2 striped and mirrored to 2 other drives
2 mirrored and striped to 2 other drives.
correct me here if I am wrong.
Now I can see in some scenarios(some Servers that have only 2 SCSI Disks) and the array is 0+1.
can someone explain this?
