I just got a Supermicro chasis:

That has a backplane that supports SAS and SATA drives but the backplane has SATA ports to be connected to the motherboard. I have a LSI Megaraid card ( that supports both SAS and SATA.

My question is can I take my SAS drive and hook it to the backplane, then use SATA breakout cables to connect to the LSI Megaraid card since the card is as SAS controller?

I wasn't sure if there were limitations on the cables themselves between SAS and SATA.

Thank you!

Just to give an update.

I went ahead and I risked one Cheetah drive to this experiment and it seemed to have worked fine.

So then I hooked up the rest of the 3 drives (4 total) and initialized a RAID 5 array on them.

So far so good. I'll install an OS and run some IO testing and report back if people are curious.

Doing same thing here - that should work fine. I've read some stuff about mixing SATA and SAS drives on the backplane you might want to watch for.

Do you want to elaborate on what you read that might cause the op issues? – Mark Henderson Dec 27 '11 at 5:51
