The upgrade from SBS 2003 to 2008 didn't go well for me. DCPromo was
fine, but somewhere through migrating accounts it failed with a generic
error message.
During this time users were unable to use the domain therefore I took the
decision to start fresh and create new user and computer accounts on the
SBS 2008 domain.
I have all my machines virtualized on one Dell 2950box. It's a monster of
a machine with two processors, plenty of hahrd disks, space and RAM but
I'm not happy. I've one single point of failure and believe me when I say,
the day it goes down is the day I'll have some serious problems. I baddly
need to buy a second box to cluster the systems so that I have something
to fall back on but I spent a hell of a lot on this box and I won't have
the money to spend on another for quite a while due to work that I want to
get done on the house.
running on the eSX box at the moment is: Windows SBS 2008, Trixbox,
Debian, Windows 2008 standard for AV etc, and a final tiny Linux box for
firewall and routing stuff.
By the way, I host a number of sites etc for people. They like Apache so
for simplicity, their sites are hosted on debian, however more and more
people are using the iPhone and like the push provided by exchange 2007 so
I'm hosting their mail on that. It's amazing how nice it all plays
together.
Back to my point. If you can avoid it, and you only have one machine to
use for ESX, I wouldn't virtualize any server that's critical unless you
are completely sure that it can be restored quickly using your backup
solution.
Speaking of backups.
With ESX, you will need to leave enough space to take a snapshot on the
datastore that you have your VM on. This basically means that as standard,
if you have a machine using 100GB, leave 200GB available in total for that
VM on the datastore. There are ways of customizing this using VMotion etc
but for one system using eSX and not ESXI, this is really not worth the
hastle.
this is my second problem. I have 4TB of space but at the moment, I just
don't have the space available to make snapshots so my backup solution is
based inside the VM's so it's not really taking advantage of what I really
wanted to get from using ESX.
So, if your thinking of virtualizing it, just be very sure that it will
meet your needs long term.

Hi,
Here are some virtualisation scenarios using Hyper-V:
http://blogs.technet.com/b/sbs/archive/2008/09/15/sbs-2008-and-virtualizatio...
More people are using Hyper-V for SBS virtualisation than ESXI.
Whilst virtualisation is going to make backups and hardware swapouts
easier, it is going to make SBS integrated backups more complex, and as
such with the current version at least I don't see any mileage in
virtualising the SBS standard server unless you want to host other servers
on the same hardware. The memory requirements for SBS 2008 are a lot more
than 2003, and you really see a performance bottleneck if there isn't the
RAM there.
I have a beta link for SBS7 at home, because I use SBS at home to get all
the server technologies cheaply, although the mainstay of what I do at
work uses the standard server products.
Thanks.
Andrew.

Andrew, the shop is small enough to start from scratch. I'd like to
virtualize the server to make backups easier and potentially move the
server from physical hardware to other physical hardware if ever
necessary. Does anyone have a download link for the public beta of SBS
7?
Thanks
Frank

Hi,
A few thoughts:
SBS isn't supported running in production under VPC. It is supported in
HyperV for sure, and possibly ESXI also, but anything else would be for
test environments only.
Why are you wanting to virtualise your SBS box?
As for upgrading, there is SBS7 in beta test at the moment, you may want
to wait for that before jumping in? You can't do an in-place upgrade
from SBS 03 to SBS 08, you can migrate the settings using the migration
tool, but you need to have a source and destination server for that to
work. You could also throw everything away and start over, backing up
mail and documents of course, depending on how many users you have on
the system.
Thanks.
Andrew.

Hi all, it is about time for me to upgrade our own internal server from
SBS 03 to SBS 08. We have had 03 running in a VM under VPC 07 for some
time now. Should we still run SBS 08 as a virtualized server? If so what
is the most accessible means of doing this, HyperV, Fusion on the Mac,
VMWare Workstation, or something else. I loved VPC but I don't think it
can work with 64 bit guest systems. Also what host hardware and OS
should I use. Any suggestions would be greatly appreciated since sighted
help is rarely available around here.
Tia
Frank
