For us the current solution is: "none at all".
The big big advantage of using geom mirror instead of a
"hardware RAID controller" is:
The disks will boot and run in _any_ system that is capable of
using the disks at all.
Dedicated RAID controllers lock you to the specific brand and
sometimes even model you use. Bad for desaster recovery.
With a geom mirrored SCSI or SATA disk, if an entire
system/mainboard/CPU fails, I simply plug the disks in the next
spare box available, boot, possibly change name of network
With hardware evolving so rapidly nowadays you cannot guarantee
to have another identical controller on the shelf when you need it.
Happened to us with ICP-Vortex (iir) controllers. ROHS - product
unavailable :-/ Successor not compatible in terms of on-disk
We are now happily running RAID 1 and RAID 1+0 with geom.
