SAS 6Gb/s Drive on a SAS 3Gb/s Controller?

Will a SAS 6Gb/s drive, such as the HITACHI Ultrastar 15K600 0B23663, work (albeit at the lower speed) when connected to a SAS 3Gb/s contoller, such as the PERC 5/i or PERC 6/i controller in a Dell PowerEdge 2970?

The reason I'm asking about backward compatibility is because I can't find a 15k RPM, 600GB, SAS 3Gb/s drive.

Thanks in advance!

Yes, the SAS2 protocol requires downward link speed compatibility ... but it is within realm of possibility that a manufacturer could make a mode page change to hardware speed to 6Gb link speed (but unlikely they would do that)

No big deal if the drives never run at 6Gb/sec due to the speed of the controller.

I just wanted to make sure that I won't run into a problem when I connect the 6Gb/sec drives to the slower 3Gb/sec controller.

So just to clarify, you're saying there should be no issues with what I intend to do, right?

Thanks,

Did you have any problems with the installation?

I actually ended up going with Dell-provided hard drives, and I don't know what kind they are. I'm out of the country until Dec. 30th, but I'll check the drive models when I'm back and let you know.
