System Center By The Numbers

As the Microsoft vs. VMware Virtualization Wars heat up, the management questions are important because 1) the management system can influence which hypervisors get deployed and 2) as hypervisors become commoditized, much of the profit to be made in virtualization will come from the management systems side of the business. Since the majority of the servers being virtualized are Windows Servers, its Microsoft's belief that customers will find it more appealing to extend the management system already in use -- System Center -- to manage both physical and virtual servers, rather than having separate management systems. Further, Microsoft is adding support for VMware's ESX products so that customers can manage both ESX and Hyper-V from the same console. So then the question is -- "How much of the market uses Microsoft's System Center?" We're told that on the server side, 45% of enterprises use it with 40% penetration rate (penetration rate refers to the percent of attached systems inside an organization), and on the desktop side, 56% of enterprises use it with an 80% penetration rate.
