But the real question is whether the "enterprise" drives would have
avoided your problem.

Maybe this is noted somewhere, but I did not realize that "copies"

provide some pointers about this?

don't think you
can move the bulk - /usr.
See:
http://docs.sun.com/source/820-4893-13/compact_flash.html#50589713_78631
Good link.
So I suppose I can move /var out and that would deal with most (all?)
of the writes.
Good plan!

be golden there.
You are suggesting booting from a mirrored pair of CF cards? I'll have
to wait until I see the system to know if I have room, but that's a
good idea.
I've got lots of unused SATA ports.

If booting/running from CompactFlash works, then I like this one.
Backing up root should be
oader on the CF
card in order to have root on the raidz2 tank
5.5. Figure out how to have the kernel and bootloader on the CF card
in order to have 4 pairs of mirrored drives in a tank, supposing #2
doesn't work
Comments, suggestions, questions, criticism?

As Russell points on in the last post to that thread, it doesn't seem
possible to do this with virtual SATA disks? Odd.

suspicion they all behave similarly dangerously, but actual
data would be useful.
Also, I think it may have already been posted, but I haven't found the
option to disable VirtualBox' disk cache. Anyone have the incantation
handy?

Another thought in the same vein, I notice many of these systems
support "SES-2" for management. Does this do anything useful under
Solaris?
Sorry for these questions, I seem to be having a tough time locating

Thanks for pointing to relevant documentation.
The manual for the Supermicro cases [1, 2] does a pretty good job IMO
explaining the different options. See page D-14 and on in the 826
manual, or page D-11 and on in the 846 manual.
I'll read though that, thanks fo
