Dont really mind - Ive got the important stuff backed up on an external drive
Just fancy having a dabble of this vsphere tbh - not sure if there will be a big performance hit though??
This is what I did:
Power off your Microserver
Download vSphere Hypervisor free (Esxi5) iso and burn it to CD. Download the vSphere Client (you will need this on a separate PC)
Get a 4GB or 8GB USB Stick and stick it in the Internal port of the microserver.
Using an external DVD drive boot up from the vSphere CD and install vSphere to the internal USB stick (here you choose whether you want static or dynamic IP, the password for the root user, whether you enable SSH or not etc)
Reboot after installation and make a note of the IP address of the vSphere installation.
Using vSphere Client on another PC log into you vSphere installation with the
username root and the password you set above.
Now you need to create your storage. There are two parts to this, the datastore and the virtual disks. The easiest way is to configure a datastore for each of your physical disks to its maximum size. So in your case you would create 1 datastore for the 250GB disk at maximum size, and 1 each for the 2TB disks at maximum size.
Once you have done this you can create your first virtual machine.
I used the 250GB disk for the OS partitions of the machines I created, and the other disks as storage.
In your case you will need 1x virtual disk of 170GB for WHS 2011 (it will partition it as a C and D drive automatically) and the rest for your Ubuntu install.
At this stage don't bother about creating Virtual disks for the storage. Do that AFTER you have installed the OS drives. Once WHS is installed, you will need 2 new virtual disks. One for your storage and one as a target for the WHS server backup.
That's it in a nutshell.
