Ian,
It would help to have some config detail (e.g. what options are you using?
zpool status output; property lists for specific filesystems and zvols; etc)
Some basic Solaris stats can be very helpful too (e.g. peak flow samples of
vmstat 1, mpstst 1, iostat -xnz 1, etc)
It would also be

I'm wondering whether your HBA has a write through or write back cache
enabled? The latter might make things very fast, but could put data at
risk if not sufficiently

A customer is running ZFS version15 on Solaris SPARC 10/08 supporting Oracle

That would be a good test. We'll try that.

After contacting LSI they say that the 9200-16e HBA is not supported in
OpenSolaris, just Solaris. Aren't Solaris drivers the same as OpenSolaris?
Is there anyone here using 9200-16e HBAs? What about the 9200-8e? We have a
couple lying around and we'll test one shortly.

The mpt_sas driver supports it. We've had LSI 2004 and 2008 controllers hang

If the pool is non-redundant and your vdev has failed, you have lost your data.
Just rebuild the pool, but consider a redundant configuration.

So, what would you suggest, if I wanted to create really big pools? Say
