The default install in Osol 0811 (which is what I just upgraded my home
NAS to) gives you a zfs root pool that various things, including swap, are
taken out of as filesystems or whatever.  (You can then attach another
chunk of space to make that root pool mirrored, if you want; I''ve done
that, using two dedicated disks for it.)

Actually, I don''t think you can really control how the 08-11 install
sets
up its root.

Because of the cost of hot-swap slots in a box, it might make sense to
share root and data on two drives, maybe.  I haven''t gone that route
myself.

I haven''t experimented with SSD in Solaris.  I''m using one as
the system
drive for an XP box, and it''s giving me terrible pause problems (I
think
this is an understood problem, I just bought too early, and haven''t
been
able to afford to junk my current SSD and replace it with an even more
expensive one).  So make sure to get current research and figure out which
ones will be good for what  you''re doing before spending money!

What are your backup plans?  RAID (or mirroring) is just the start, to
protect you from many hardware issues.  (The size of your array makes this
more of an issue; mine is two 400GB mirrored pairs, so I can back it up to
an external 1TB drive easily.)

[Just do not want to be misleading]

I think there is one aspect of the Zhou style is heavily misleading.
And that is how do we deal with ladies.

Personally, I have my opinions about ladies being open and career-minded, but
those are not important.

What is important, would be how should we deal with ladies at a professional
level.
To me personally, if a lady claims to me as a professional, not as a female,
then I will take her as a professional, and will consider very little of the
general policy for being a gentleman.  Otherwise, it would not be fair in
corporations, in my personal view.

But if the lady does not claim "professional" to me, then my
approaches would be completely different.
[and those approaches are not for sharing, since they are not IT related.]

I don''t know if this email is even relevant to the list discussion. I
will leave that conclusion to the smart mail server policy here.
:-)
But if I have sent through some misleading text, this email is for the
clarification.

Best,
z
