We do have kind of good experience with LSI, but we use their controllers only 
to build our own software raid1. And to access the SAS-streamers.
But nowadays the intel-server-boards seem to have enough sata ports for lots 
of disks. And why should I do raid1 on the disks in hw when I put a raid1 on 
the disks in the network?

Have fun,
