x2100 M2

[Stephen Schaff]

I'm thinking about buying the Sun x2100 M2 for OpenBSD 4.0. I've  
purchased one for a  client that's running linux. I set it up but  
don't admin it. I don't use linux, but I really like the hardware. I  
want to do RAID1 with it, which the motherboard supports. However,  
I'm told that the RAID controllers they put on motherboards are just  
glorified software RAID and don't even compare to real hardware RAID.  
Further, I don't think that OpenBSD would even work with the  
motherboard RAID controller - please correct me if I'm wrong.

So, I'm looking for a suggested course of action regarding the x2100 M2.
Anyone have any experience with it - especially keeping RAID1 in mind?

Best Regards,
Stephen
