6. Connect the SAS/SATA cables from the backplane (or hard drives) to the RAID
module (see Figure 3 ). For information regarding connecting the recommended
Right-angle end or Vertical end of the SAS/SATA cable to the SAS connectors of
the controller, see your server/workstation board or chassis documentation. Make
sure the cables are properly connected to the controller.
Note: System throughput problems can occur if non-standard SAS cables are used.
To minimize the potential for problems:
✧
Use cables no longer than ten meters for SAS and one meter for SATA. It is
better to use the shortest possible cables. The cable length should be reduced
by about one foot (.33 meters) if using a backplane.
✧
You may connect one device per SATA/SAS cable either as a device or as an
expander.
✧
Route SAS cables carefully.
✧
Use only “straight” SAS cables, not “cross-over” SAS cables. .
