I've managed to get the data transfer to work by rearranging my disks
so that all of them sit on the integrated SATA controller.
So, I feel pretty certain that this is either an issue with the
Supermicro aoc-sat2-mv8 card, or with PCI-X on the motherboard (though
I would think that the integrated SATA would also be using the PCI
bus?).
The motherboard, for those interested, is an HD8ME-2 (not, I now find
after buying this box from Silicon Mechanics, a board that's on the
Solaris HCL...)

So I'm not considering one of LSI's HBA's - what do list members think
about this device:

I believe the MCP55's SATA controllers are actually PCI-E based.
I use Tyan 2927 motherboards. They have on-board nVidia MCP55 chipsets,
which is the same chipset at the X4500 (IIRC). I wouldn't trust the
MCP55 chipset in OpenSolaris. I had random disk hangs even while the
machine was mostly idle.
In Feb 2008 I bought AOC-SAT2-MV8 cards and moved all my drives to these
add-in cards. I haven't had any issues with drive hanging since. There
does not seem to be any problems with the SAT2-MV8 under heavy load in
my servers from what I've seen.
When the SuperMicro AOC-USAS-L8i came out later last year, I started
using them instead. They work better than the SAT2-MV8s.
This card needs a 3U or bigger case:

This is the low profile card that will fit in a 2U:

They both work in normal PCI-E slots on my Tyan 2927 mobos.
Finding good non-Sun hardware that works very well under OpenSolaris is
frustrating to say the least. Good luck.
