Server 2008 Hibernation ON by default

I was investigating an issue today where there was low disk space on one of my VM's. Come to find out, after running SpaceMonger it showed a 4 GB file hiberfil.sys. I remember only seeing this file on laptops when hibernation is turned on. I am not sure why anyone would want hibernation turned on for a server. There was no option to turn off hibernation in the GUI so I had to turn it off using the following command at the command line:

powercfg.exe /hibernate off
