Power and thermal monitoring for the IBM system z10

In May 2007, IBM announced Project Big Green, an initiative M. R. Vanderwiel designed to accelerate the adoption of green technologies and services in order to make data centers more energy efficient. An integral part of this strategy is to enable power and thermal monitoring on all IBM server platforms. The IBM System z10e server delivers these capabilities and is the first system in its class on the market to provide this functionality. This paper introduces the z10e power and thermal monitoring architecture and provides an end-to-end view of the underlying technology, from reading voltage and current to visualizing trending information in the Active Energy Manager extension to IBM Director.
