Considering Virtualization
in [Windows Servers]

From: Matthew on 20 Apr 2010 16:34 Hello Newgroup, We need to upgrade our 4 year old SBS box. I am totally new to virtualization and wondering if these circumstances warrant making the jump. We've got approx 30 users, and approx 75 mailboxes. We don't run anything extra. We're nonprofit, which means that MS licensing costs are negligable, but it also means that our IT budget is tiny - I'm here approx 10 hours a week for general support, higher level needs get outsourced. I had been considering the following path: > Get a new server, without a tape drive (old server's tape drive recently > replaced) > Put Server 2008 and Exchange 2010 on new box. > Migrate (either manually or with a tool) users and data to new server. > Wipe old server, install Server 2008, let it run backups and antivirus. But it's been suggested that I consider instead the following path: > Get a new server (with ample RAM and processing power).

As I said, IT hours are precious few for this organization. Would the labor be similar between the two paths?

I'm game to try this, if it makes business sense, but don't want the additional learning curve if it's just technology for technology's sake. Not sure if my list of advantages makes it worth the time. Thanks in advance for your thoughts! Matthew

I'm not hearing a compelling reason to migrate to virtualization. Virtualization would be good if you have multiple systems you want to consolidate to one system. The only real reason that I see in what you have provided is the ability to keep the old SBS system around as a VM. However, SBS is funny in the fact that it wants to control the network. So, either the SBS VM would be the DC, or it won't be on in the same domain as the new server. Don't get me wrong, virtualization is great when used for the proper reasons. 2k8 includes Hyper-V and can be added at any time when wanted / needed. I would suggest that you not use this server migration as the learning curve for virtualization with out having messed with it at least on a workstation before. Wait until you have an actual need. > Not sure if my list of advantages makes it worth the time. I'm not seeing any real advantage in the scenario that you have described. The only thing that suggests using a separate VM to me is possibly putting a Blackberry Enterprise Server in a VM. Even then, that VM could run on top of 2k8 running on raw hardware. Grant. . . .
From: Charlie Russel - MVP on 22 Apr 2010 09:56 There are valid reasons to virtualize, but they aren't compelling in your case, UNLESS you think you're going to want to run a Terminal Server or have a need to run SQL Server. In either case, you're going to need two servers, and virtualization makes sense. With your current plan, you should be considering SBS 2008, not standalone Windows Server, if you want to stay on a non-virtualized single box. Exchange on your domain controller, all in one box, is really an SBS solution, not a standalone one. On the other hand, if you want to move to standalone products, then virtualization makes sense since it allows you to put Exchange on a separate server while still only buying a single physical box. Virtualizing your old SBS box makes little sense, IMO. What business need do you have for virtualizing it? What do you gain by doing so? -- Charlie. http://msmvps.com/blogs/russel "Matthew" <adminNOSPAM(a)sa-intl.org> wrote in message news:O6V$QjM4KHA.5324(a)TK2MSFTNGP05.phx.gbl... > Hello Newgroup, > > We need to upgrade our 4 year old SBS box.
