I've posted the bonnie++ data the other day (14x RE4 as RAID 10,
2x RE4 as RAID 1 root). I've used two LSI SAS3081E-R. No idea
about IOPS, which benchmark should I run?

An interesting variation on this is to use a 24-drive chassis
(with 2x3.5" internally, populated with 4x Intel SSD for ZIL
and L2ARC), use 3x LSI SAS3081E-R and to use Opensolaris with 
zfs on top of that. There's a thread on zfs-discuss@ ongoing right now:
