Works fine, although it appears that the ips driver seems to want the 
5.11 firmware on the ServeRAID card, instead of the newer 6.X series.  I 
did some trivial digging into the ips source but didn't see any specific 
comments or macros defining a desired firmware level, but 5.11 firmware 
works fine for me, whereas I know a few people have seemed to have 
problems, possibly due to firmware and drive incompatibility (I 
currently work at IBM and can say definitively 5.11 and 6.X firmware and 
drivers do not want to play together...)

ServeRAID 3L 5.11 firmware
