since when does "support" equate to "patches" (only)? There's much more to 
support than just supplying (or even creating!) patches.

(oh, btw: wasn't IPS created in part to get away from the whole patch ... 
ermm ... issue? ;-)

Does Sun now offer patches for OpenSolaris?  Note that Sun also 
"supports" Linux and Windows on their hardware.

Happyness is a fresh upgrade ...

OpenSolaris (as a distribution) is ABSOLUTELY supported by Sun. Take a 
look at the datasheet from opensolaris.com and sun.com

Of course we are going to have several servers, but we were hoping to be able 
to share all the folders from one at a time.  We want to use the mirroring 
capabilities in ZFS to take disk from two san's in different buildings, and 
mirror them up in the zfs pool.  We will also have a second server in another 
building ready to do an import of the pool, highjack the IP and share the 
files.  This way we would be safe in case of san failure, server failure and 
problems in one of the buildings.  

It all cooks down to if ZFS is capable of sharing this amount of filesystemes 
on one server though.  If it takes a week to make the filesystems, and hours to 
boot the server (an I guess importing the pool on the other server), that would 
be a big drawback...

I know OpenSolaris is not officially supported by SUN in any way, but most of 
the development seems to be going on for OpenSolaris, and then gets implemented 
into Solaris when it's stable and ready.  This is why I wanted comments on the 
status of this in this forum.  I was hoping for some reassuring that this would 
be ok in the upcoming release of Solaris :)

Today it's 30. Oct, and sun.com still says "Note: Solaris 10 10/08 availability 
is planned for the end of October.".  I am waiting in anticipation, and can't 
wait to test this out in the new release :)

You'll have to solve this issue by using multiple ZFS servers so that
the number of filesystems per server is a reasonably good fit with
ZFS' current capabilities.  OTOH  ZFS is improving in this arena over
time and, even with multiple servers, ZFS will still provide a cost
effective solution.   In any case, with 5 ZFS servers, would it not be
better to have only 20% of your user community affected if a server
were to have a catastrophic failure?  (rhetorical question)

> Any official input on how this will be in the upcoming release of Solaris 10?

You won't get any "official" input on Solaris (the commercial product)
related topics on this list - which is dedicated to OpenSolaris.  But,
to give you something that resembles an answer, Sol10 Update 6 is
based on Build 88 AFAIR.  So looking at the features/performance of
that release will give you a good feel for Sol 10U6 .. the usual
disclaimers YMMV etc.
