Fantec SRC-2080x7 connect backplane from SAS to Sata




I've read this topic: How exactly does a SAS SFF-8087 breakout cable work? + RAID/connection questions



Which basically explains that you can go from sata to SAS, but not vice versa.



However, from the store page of the Fantec SRC-2080x7 chassis I've seen a few reviews where people seem to use a breakout cable to connect the sata ports from the motherboard to the Mini SAS port (SFF-8087) on the backplane (where sata HDD's are connected).



Is there an exception to this backplane regarding this cable?



Because the SFF-8087 breakout cable doesn't seem to be working for me. Which would be consistent with the topic I linked above, though I'd be suprised if the people in the reviews haven't tested it before posting their review.




Note: The store page is in german and I've been translating everything to english by using Google Translate



This is the page of the chassis by the manufacturer, but also in german (even the english language at the top-right doesn't help).



EDIT: My backplane model is DH-6GMSAS-03A


Answer



SFF-8087 connectors are frequently used for SATA multi-port connections as well - on backplanes or sometimes even on RAID controllers. In reverse, you can use a SFF-8087-to-4xSATA fanout cable to connect standard on-board SATA ports to a (passive) SAS cage or the Fantec case you've linked to, where you plug the SATA drives (obviously, SAS drives would fit but won't work).



That said, I've seen some really low-quality fanout cables that were hard to correctly plug into the SFF-8087 receptacle - and in one case extremely hard to remove again. Make sure everything is plugged correctly, the 8087 is latched, and the drives are powered before or together with system power.
