Running multiple VM's on one Server

[Pazza]

Stupid question time, could you not handle it in a similar way to WMS/cPanel does? So you have one internet facing server, that then redirects the traffic internally, depending on what domain name is typed in.

For example, someone types in www.one.com, so the server routes that to the first IP, if they type in www.two.com and thus is routes to the second IP. Your internet facing server is a VM that is solely there to re-route the traffic.

IIRC, I think it's a 301 redirect, only you're routing it to an internal IP, instead of an external IP.

this is pretty much the idea - but it's choosing the right tool/server/system (whichever) to use and some insight on how to setup

If it's just the website traffic then virtual host is your answer...

not just web traffic, also want exchange and full features of SBS available from each VM.

No that won't work, because a 301 is a client side thing. ie The server says to the client (IE/Firefox etc) "301: Look here instead" and the client then requests the new address, which means it'll look for 192.168.10.1 or whatever. As the client is somewhere on the Internet and that's a non-routable IP address it will fail (unless 192.168.10.1 exists on it's own local network in which case it will go take a look there instead).

Pazza - the only real way of doing what you want is to request two (or more) static IP addresses from your ISP. Of course private individuals can get static IP addresses:

In short, the way you are trying to do this will not work.

SBS 2011 has a minimal memory requirement of 8GB and the OS partition of 120GB, so your looking at 16GB and 240GB just with those two VM's
I have SBS 2011 running on my ESXI 4.1 box and it idle's using 8GB, most would recommend 12-16GB

From the datacentre side, to have a working scenerio of incoming mail flow, remote access etc.. you will need multiple external IP addresses and then with the Draytek, port forward the required ports to each server with its own dedicated IP.

Overcommit Dude...Overcommit

because of the way exchange will grab any allocated RAm to it , that kind of thing will happen , but you'll find that running 2 SBS VM's on a given box should page share pretty well. I'd be tempted to put an SSD into your host and push the VM swap files onto it. Failing that add some more memory.

In terms of drive size , thin provision it - does the install ( for a test ) actually consume 120Gb of drive space ?

[Pazza]

can't I use reverse proxy to resolve which VM to direct all requests for web/exchange etc.?

[b0redom]

Well you can as I said in an earlier post, but that will require another VM, or a configuration of some pass through stuff. I know it will work for web traffic, but not sure about exchange etc.

I might be missing the point, but why run 2 SBS installs? Why not just host both domains on one Exchange server? Then host the webtraffic on virtual hosts.


Granted, not the most secure of options, but if you're playing with Technet and can't get a second static IP it seems the most sensible option to me.
