I've got a couple of questions for folks;
1. I've googled and browsed around quite a bit, and almost all the
stuff I can find relating to using databases against ZFS/comstar is
talking about OLTP-style databases. Is there anyone out there
getting reasonable results with a data-warehouse workload?
2. Is there any work going on with comstar to allow it to do
different size block IOs instead of it's current approach?
Yes, it's coming in changes expected to be integrated in build 115 or
116 of OpenSolaris. But different upon creation, not a change on the
fly....
3. Lastly... is there any chance of adding a knob to sbdadm to
allow us to specify a block size when we create a LU, especially in
the case of raw disk or SVM back-end targets?
There will be a management paradigm where you will be able to tweak
the LU block size on creation:
blk - block size in bytes in 2^n

Thanks
