Figure 3. Connecting Cable Between The Raid Module And Drives/Backplane - Intel RMS2MH080 Hardware User's Manual

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. .
