Connecting cables from the system board to the backplane
Your server has two SAS connectors on the system board to support up to eight hard disk drives.
If you connect the mini-SAS to mini-SAS signal cables from the system board to the backplane, you can
configure RAID for the hard disk drives using the functions of the ThinkServer RAID 300 (also known as the
onboard SAS software RAID).
Use the following instructions to connect cables from the system board to the backplane:
1. For hard disk drive 0 to hard disk drive 3, use a mini-SAS to mini-SAS signal cable and connect the
