The Cooperative Expendable Micro-Slice Servers (CEMS) project evaluates low cost, low power servers for high-scale internetservices using commodity, client-side components. It is a followon project to the 2007 CIDR paper Architecture for Modular Data Centers [11]. The goals of the CEMS project are to establish that low-cost, low-power servers produce better price/performance and better power/performance than current purpose-built servers. In addition, we aim to establish the viability and efficiency of a failin-place model. We use work done per dollar and work done per joule as measures of server efficiency and show that more, lowerpower servers produce the same aggregate throughput much more cost effectively and we use measured performance results from a large, consumer internet service to argue this point.
