Friends.
I have same problem in Dell PE 2850 Server, but, in <a href="http://www.sun.com/bigadmin/hcl/data/sol/systems/details/806.html" target="_blank"> http://www.sun.com/bigadmin/hcl/data/sol/systems/details/806 .html</a> this server is not certified yet (I believe it).
Any idea?
It seems that there is a driver now available for the PERC 4e/Di

hope it helps because I am also planning to get a couple of 2850.
I got the best price out there comparing HP DL380, Fujitsu-Siemens RX300 and any available from SUN.
