SATA to SAS

[twin_suns]

So I've been searching around I'm not 100% sure of the answer. If you have a hard drive enclosure full of SATA drives that has a Mini-SAS HD backplane, and (using a reverse breakout cable) you connect it to SATA ports that have a JMB585 or ASM1166 controller, will this work?

 

I assume not, and that the motherboard has to to have a built in SAS controller on its SATA ports for this to actually work? That or have to get a SAS HBA.

Assuming there's a SAS expander it won't work, it will work for direct connect backplanes, without an expander, i.e., that have a separate connection for each drive.

No expander, just a single breakout cable from the motherboard's SATA ports to a SAS connector on a backplane. So it sounds like it will actually work, thanks.

I meant a SAS expander included with the backplane, if the backplane has fewer connections as the number of disks it supports it includes a SAS expander.

Ah right, so its a 8 drive backplane with two SFF-8643 ports.

In that case there shouldn't be any expander.
