Like I said I use Santools.  However, David Lethe, the author of Santools,
who was a great help to me in working through this, informed me that from
Solaris sg_write_buffer should be set to --mode-7 and possibly even set
--length to 16384.    I have not tested this.

For me Santools has been well worth it's investment on every ZFS server
I've deployed.
