MOSS Virtualization Configuration Quandry

  Asked By: Jeanne    Date: Nov 08    Category: MOSS    Views: 815

We have a small network with around 25 users internally and ultimately
a few hundred accessing it externally for incidental use. We are
contemplating some of the following when it comes to configuration:
1. Install MOSS Enterprise on a VM and point it at a seperate SQL
2. Install MOSS and SQL on the same VM
3. Install MOSS on a VM on the same machine that hosts our enterprise
SQL server.
4. Do not install MOSS on a VM for performance reasons

In terms of disk I/O, I understand that the recommendation is to
install MOSS/the VM on a dedicated drive/array and the SQL DB on a
different drive/array.

What do you think? Which one would you choose and why? (With the
interest of keeping the cost low, ease of backup (entire machine may be
downed nightly to back it up as a single VM instance).

1 = workable, depends on how much juice the host has, and what
virtualization technology you are using.

2 = disaster

3 = bad practice

4 = depends. If you have light usage, you can probably put it on a VM.
Either way, SQL needs hardware and separate disk.

We have the current configuration  which works just fine at this point:

* WFE as an MS Virtual server  guest
* Index Server as an MS Virtual Server guest
sql  2005 sits on a "bad mamajamma" x64 cluster

Option 3 should not even be considered.

Remember, if you are going to allow external access you will need to
let users  in through a firewall.

We went a slightly different route (but close to number 1):

SQL on its own physical server
2 Web and one Index server  Virtualized on one physical machine.

The two virtualized web servers are configured as 1 server on the Lan and one in
a DMZ. (2 physical NIC's on the hardware)

The rules allow Auth and SQL across the DMZ for the web server.

I have about 200 Lan users  and about the same number of external access users.

Is there any way to use VMs for easy backup/restore as suggested by

Answer #6    Answered By: Cheyenne Lewis     Answered On: Nov 08

If you have your vm's set up to boot from san, yes. However you can create an
ISO that will be a static copy of the server  that can be moved to any virtual

This is utilizing Microsoft Virtual Server components.

If you've got the $$ for VMWARE, it's a piece of cake.

Answer #7    Answered By: Liana Alston     Answered On: Nov 08

For it to be a piece of cake, do all servers on the farm need to be on
the VMWare LUN? How do you bring them back  in a consistent fashion?

Sorry - I meant to ask "do they need to be on the SAME VMWare LUN..."

Answer #9    Answered By: Emerson Franks     Answered On: Nov 08

Not as familiar with VMWare but with Microsoft Yes, I think I remember the
ability to move with "vmove" the image from one server  to another without it
being on the same LUN.

Generally with VMware, there's a server dedicated  to Management of all virtual
servers, Microsoft hasn't quite caught up, the Host server has the ability to do
a lot with its own virtual servers, but for example, a vmware system has the
ability to have a host set up as a hot standby, should a physical server fail,
it can automatically migrate all the virtual server to predetermined hosts.

The product you're referring to is VMWARE Virtual
Center. This allows VMWare hosts connected to the
same SAN lun the ability to swap VM's from one host to
another in seconds. Having that SAN connectivity also
allows you to create new VM's from snapshot templates
very quickly.

hate to offer up information when it's been a while since I've worked
with the product.
