I have a 2950 with (what from linux) is called a PERC 5/i with SAS drives. I 
worked fine even with 4.3 :-) (no tweaking, no fiddeling)

The driver is called megaraid_sas, and yes it is true hardware raid.

Here's the details of what I have:
 [root at tbox3 ~]# lspci  -s 02:0e
 02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID controller 5
 [root at tbox3 ~]# lspci -vn -s 02:0e
