Rack Server Virtualization Add-in provides the capability to pull the rack-server data either from an Excel spread sheet or from the user and render the Visio diagram. This amazing Add-in from Microsoft Office Visio 2007 Professional helps you plan virtualization. With over 70% of server hardware being under-utilized, this very valuable tool can draw a clear picture of your hardware utilization. This tool auto-generates the diagram of your rack and provides clear server details from a linked Excel template. Analyze your racks and servers using WMI or get the utilization data over time using the Operations Manager connection.
