  • 1. Applied Math Modeling Inc
    Data Center Airflow Modeling Tools
  • 2. Applied Math Modeling Inc
    Founded in 2008 as a spin-out of the ANSYS Corporation.
    Responsible for Development, Sales, & Support for the CoolSim Data Center Modeling application through partnership with ANSYS Inc.
    Focused on delivering cost-effective engineering simulation tools using a SaaS model of delivery & support.
    Staffed by industry experts in the field of CFD sales, development, and support.
  • 3. Data Center Market Overview
    EPA report issued in August of 2007:
    1.5% of total US electricity is consumed by data centers 61BkWh
    Cost of electricity $4.5b
    Expected to grow to 100BkWh within 5 years ($7.4B)
    Among the key recommendations, improved airflow management is the most cost effective measure yielding up to 30% energy reduction in operational costs.
    “Optimize data center airflow configuration using CFD modeling and visualization tools”
  • 4. Data Center Energy Consumption
    Dominant factors are IT Power and Cooling Power.
    IT Load, CRAC/Chiller make up 75% of total
    UPS, PDU, Switchgear are all 2nd order effects

  • 5. Benefits of Data Center Airflow Modeling
    The user creates a model of the data center using CoolSim for performing “what if” scenarios of potential changes
    What is the effect of adding servers to the data center?
    What happens if a cooling unit(s) fails?
    What is the effect of hot aisle/cold aisle containment?
    What is the maximum IT load a given data center can handle?
    Allows users to predict the and temperature anywhere within the data center and make informed decisions on cooling or IT equipment placement.
    Provides the necessary information for significant cost savings in new data center designs and/or reduce operational costs of existing data centers.
  • 6. How Does CoolSim Work?
    CoolSim incorporates ANSYS Fluent CFD technology
    Same software used in Aerospace and Automotive
    All meshing, solving, and post processing are performed on a remote HPC cluster.
    CoolSim uses a subscription based SaaS (Software as a Service) model where price is correlated to anticipated annual use.
  • 7. How Does CoolSim Work?
    CoolSim is a highly automated tool
    User builds a model of a data center using easy to use GUI
    Includes libraries of common cooling equipment and equipment racks, and IT equipment
    Model is automatically meshed, solved, and post processed
    Embedded knowledge drawing upon 20 years of CFD modeling experience from aerospace and automotive markets
    Results are presented in 3D HTML output reports
    Eliminates costly “human time” in post processing
    Eliminates “human error” in post processing output plots
    User learning curve measured in hours
    Run times average less than an hour
    Multiple jobs can be run concurrently
  • 8. CoolSim Key Features
    Modeling Capability
    Fully coupled CFD analysis powered by ANSYS CFD Solvers
    Model raised and non-raised floor data centers
    Models in-row and overhead supplemental cooling solutions
    Server specific rack modeling with gaps and blanking
    Ability to model supply ducts and diffusers
    Ability to model under-floor and overhead cable trays, under-floor pipes, baffles, blocks, PDU’s, etc
    Ability to model ducted ceiling return data centers
    Ability to model CRAC failure scenarios efficiently and quickly.
  • 9. CoolSim Key Features
    Output Capability
    Thermal maps at rack inlets, outlets and throughout data center.
    Detailed airflow patterns in the room showing return airflow path of hot air revealing any mixing or short circuiting currents.
    CRAC performance report with return and supply air temperature and relative load balancing on various units.
    Rack by rack cooling performance evaluation and compliance with the ASHRAE recommended thermal guidelines.
    Airflow patterns and static pressure distribution in supply plenum.
    Airflow rate (CFM) prediction for each vent tile and cable cutout
    3D models of all visual output with high quality 2D image output.
    Animations of supply and return air path lines, temperature planes in X, Y and Z, and isothermal surfaces @ 2 degree intervals.
  • 10. 3D Rack Thermal Maps
  • 11. Performing “What-if” Studies
    Can we reduce inlet temperatures by simply adding low cost baffles to reduce rack recirculation?
  • 12. Results of Adding Baffles to Racks
    By adding simple baffles to racks, recirculation is reduced and server inlet temperatures drop.
  • 13. CoolSim Automated Output Reports
    Allows the easy comparison of multiple scenarios
  • 14. Summary
    The density of computer equipment will continue to increase compounding cooling problems.
    Typical data centers draw 2X more power than required by the IT equipment alone for cooling the computer equipment.
    Increasing the thermal efficiency of the data center can create savings from 30-70% per year in operational costs.
    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.
    The potential electricity cost savings from a 1MW data center are in the range of $2-4M over a 10 year period.
