No problem, I think the mpt2sas driver appeared in kernel around 2.6.3X series.

Today I installed my drives into the SAS enclosure. Everything is
working great and I'm getting maximum speed from all drives with
simultaneous access. So far I have not experienced any errors or
problems. Hopefully your luck is as good as mine!

Here is how it looks in dmesg:

The disks appear as SCSI disks like normal, but with the SAS address included:
