EETCO: A Tool to Estimate and Explore the Implications of Datacenter Design Choices on the TCO and the Environmental Impact

In this paper, the authors present EETCO an estimation and exploration tool that provides qualitative trends of data center design decisions on Total-Cost-of-Ownership (TCO) and environmental impact. EETCO has the ability to capture the implications of many parameters including server performance, power, cost, and mean-time-to-failure. The tool includes a model for spare estimation needed due to server failures and performance variability. The paper describes the tool model and its implementation, and presents experiments that explore tradeoffs offered by different server configurations, performance variability and ambient temperature.
