The emergence of power optimized hyperscale servers is leading to a revolution in Data Center design. The intersection of this revolution with the growth of Cloud Computing, Big Data and Scale Out Storage solutions is resulting in innovation at rate and pace in the Server Industry that has not been seen for years. One particular example of this innovation is the deployment of ARM based servers in the Data Center and the impact these servers have on Power, Density and Scale. In this presentation we will look at the role that Xen is playing in the Revolution of ARM based server design and deployment and the impact on applications, systems management and provisioning.
