CoolSim Overview

  1. 1. Applied Math Modeling Inc<br />Data Center Airflow Modeling Tools<br />1<br />
  2. 2. Applied Math Modeling Inc<br />Founded in 2008 as a spin-out of the ANSYS Corporation.<br />Responsible for Development, Sales, & Support for the CoolSim Data Center Modeling application through partnership with ANSYS Inc.<br />Focused on delivering cost-effective engineering simulation tools using a SaaS model of delivery & support.<br />Staffed by industry experts in the field of CFD sales, development, and support.<br />2<br />
  3. 3. Data Center Market Overview<br />EPA report issued in August of 2007:<br />1.5% of total US electricity is consumed by data centers 61BkWh<br />Cost of electricity $4.5b<br />Expected to grow to 100BkWh within 5 years ($7.4B)<br />Among the key recommendations, improved airflow management is the most cost effective measure yielding up to 30% energy reduction in operational costs.<br />“Optimize data center airflow configuration using CFD modeling and visualization tools”<br />3<br />
  4. 4. Data Center Energy Consumption<br />Dominant factors are IT Power and Cooling Power.<br />IT Load, CRAC/Chiller make up 75% of total <br />UPS, PDU, Switchgear are all 2nd order effects<br />Source: Uptime Institute<br />4<br />
  5. 5. Benefits of Data Center Airflow Modeling <br />The user creates a model of the data center using CoolSim for performing “what if” scenarios of potential changes<br />What is the effect of adding servers to the data center?<br />What happens if a cooling unit(s) fails?<br />What is the effect of hot aisle/cold aisle containment?<br />What is the maximum IT load a given data center can handle?<br />Allows users to predict the and temperature anywhere within the data center and make informed decisions on cooling or IT equipment placement.<br />Provides the necessary information for significant cost savings in new data center designs and/or reduce operational costs of existing data centers.<br />5<br />
  6. 6. How Does CoolSim Work?<br />CoolSim incorporates ANSYS Fluent CFD technology<br />Same software used in Aerospace and Automotive<br />All meshing, solving, and post processing are performed on a remote HPC cluster.<br />CoolSim uses a subscription based SaaS (Software as a Service) model where price is correlated to anticipated annual use.<br />6<br />
  7. 7. How Does CoolSim Work?<br />CoolSim is a highly automated tool<br />User builds a model of a data center using easy to use GUI<br />Includes libraries of common cooling equipment and equipment racks, and IT equipment<br />Model is automatically meshed, solved, and post processed <br />Embedded knowledge drawing upon 20 years of CFD modeling experience from aerospace and automotive markets<br />Results are presented in 3D HTML output reports<br />Eliminates costly “human time” in post processing<br />Eliminates “human error” in post processing output plots<br />User learning curve measured in hours<br />Run times average less than an hour<br />Multiple jobs can be run concurrently<br />7<br />
  8. 8. CoolSim Key Features<br />Modeling Capability<br />Fully coupled CFD analysis powered by ANSYS CFD Solvers<br />Model raised and non-raised floor data centers<br />Models in-row and overhead supplemental cooling solutions<br />Server specific rack modeling with gaps and blanking<br />Ability to model supply ducts and diffusers<br />Ability to model under-floor and overhead cable trays, under-floor pipes, baffles, blocks, PDU’s, etc<br />Ability to model ducted ceiling return data centers<br />Ability to model CRAC failure scenarios efficiently and quickly.<br />8<br />
  9. 9. CoolSim Key Features<br />Output Capability<br />Thermal maps at rack inlets, outlets and throughout data center.<br />Detailed airflow patterns in the room showing return airflow path of hot air revealing any mixing or short circuiting currents.<br />CRAC performance report with return and supply air temperature and relative load balancing on various units.<br />Rack by rack cooling performance evaluation and compliance with the ASHRAE recommended thermal guidelines.<br />Airflow patterns and static pressure distribution in supply plenum.<br />Airflow rate (CFM) prediction for each vent tile and cable cutout<br />3D models of all visual output with high quality 2D image output.<br />Animations of supply and return air path lines, temperature planes in X, Y and Z, and isothermal surfaces @ 2 degree intervals.<br />9<br />
  10. 10. 3D Rack Thermal Maps<br />
  11. 11. Performing “What-if” Studies<br />Can we reduce inlet temperatures by simply adding low cost baffles to reduce rack recirculation?<br />
  12. 12. Results of Adding Baffles to Racks<br />By adding simple baffles to racks, recirculation is reduced and server inlet temperatures drop.<br />
  13. 13. CoolSim Automated Output Reports<br />Allows the easy comparison of multiple scenarios<br />13<br />
  14. 14. Summary<br />The density of computer equipment will continue to increase compounding cooling problems.<br />Typical data centers draw 2X more power than required by the IT equipment alone for cooling the computer equipment.<br />Increasing the thermal efficiency of the data center can create savings from 30-70% per year in operational costs.<br />Using CoolSim CFD based modeling as a means to predict potential improvements Data Center efficiency is very cost effective and necessary as part of the design or modification process.<br />The potential electricity cost savings from a 1MW data center are in the range of $2-4M over a 10 year period.<br />14<br />
