2 BCS Data Centre Simulator Overview of Tools Structure of the BCS Simulator Input Data Sample Output Development Path

3 Overview of Tools

4 Tool Coverage Existing tools Computational Fluid Dynamics Server benchmarking Chiller technology comparisons Carbon calculators Device specific comparators

5 Tool Problem The data centre is not a set of independent components that can be individually tuned The data centre is a complex and interdependent system Only a holistic tool can give useful answers

6 BCS Simulator Coverage Areas Application Workload IT Device PDUs UPS Air Flow CRACs Climate Chiller Power Cost Energy Use Carbon Intensity

7 BCS Simulator Understands Variability Data Centre Layout Air Flow Location CRAC Load Energy Cost Variation Application Workload IT Device PDUs UPS Air Flow CRACs Climate Chiller Power Cost Energy Use Carbon Intensity Time Workload Electrical Load Electrical Load Total Thermal Losses Total Thermal Losses Time Climate Time Everything Else Source of Energy

8 BCS Simulation Tool The BCS model is the minimally complex solution to cover the problem domain The simulator implements the model The user interface provides a wrapper for the simulator

9 Framework Tool One tool to cover the entire system, allowing the simulation of components in a realistic context. No need to develop more partial tools, you can now contribute to the open, trusted tool instead.

10 Framework Tool Designed to facilitate the incorporation of new or enhanced component models and data Publish performance data in standard formats that we can use to compare devices
