For a new server build, I'm trying to connect a SAS HDD backplane (SFF-8643) to a SATA motherboard. From my research, this should be possible using reverse breakout cables.
I bought and installed two "SFF-8643 to 4x SATA" reverse breakout cables, but when I start the machine it does not recognize any of the disks (all SATA) on the backplane. As a spot test, I connected one of the disks directly to the mobo and it worked fine.
Is my understanding correct that this configuration should work? What other troubleshooting can I do?
