10 - 20 m copper 30 - 50 m optical It depends on the controller and the OnTap version. You can have a look in Netapp Hardware Universe.

Hello,
Does anybody know if there is a maximum end-to-end/point-to-point distance for *SAS copper* cables in a stack?
The Universal SAS Cabling Guide provides the following maximum distances for SAS optical but makes no mention of a maximum distance for SAS copper.
/If you are using SAS optical multimode breakout cables, the following parameters apply:/ / / /• The point-to-point (QSFP-to-QSFP) path of any multimode cable cannot exceed 150 meters/ /for OM4 and 100 meters for OM3./ / / /• The total end-to-end path (sum of point-to-point paths from the controller to the last shelf)/ /cannot exceed 510 meters./
Just wondering if there is also a maximum for SAS copper.
Thanks, Phil
