1 Optimum Climate Control For Datacenter - Case Study T. Prabu March 17 th 2009

2 Agenda 2 About EDEC (Emerson) Facility Data Center Details Design Considerations & Challenges Layout Design CFD Analysis Of Datacenter Summary

3 About EDEC (Emerson) Facility 3 New Facility Area (Sq Ft) Built Up: 240,000 Carpet: 185,000 No Of Floors: Basement + Ground + 5 Total Power Requirement Connected Load: 4000 KVA, Demand Load: 3030 KVA Power Back Up: 5 X 750 KVA DG Sets Capacity 3 Floors (Ground, First and Second) Total Capacity 650 Seats / Workstations Laboratories Covering 20,000 Sq. Ft

4 Data Center Details 4 Area 1520 Sq.Ft Location Ground Floor Tier 3 Class Data Center 24 X 7 Monitoring Current Capacity Up To 15 Racks 42 U (800 X 1000), Approx. 80 Servers, Provision For 20 Racks 100% Redundancy In Network, AC And Power Fully Protected From Fire And Water Leakage 4 GB Fiber Network Back Bone With 1 GB Till Desktop More Advance Core Switches ( Layer 3 Switches) For Switching And Routing IP Telephony System High Capacity Data Storage Devices Deployed In Data Center

5 Design Consideration & Challenges 5 Energy Efficient Datacenter Optimize Air Management Right Sizing Of The Datacenter Solution Provided By A Single / Multiple Vendor Raised Flooring And Overhead Space Hot & Cold Aisle Design Perforated Tiles & Cabling Redundant Power Supply Separated Electrical Room & Datacenter Safety Measures Fire Detector / Water Leakage Sensor / VESDA-early Fire Detection / Gas Release Panel To Suppress The Fire In A Minute Automatically Precision Air-conditioning System For Maintaining The Climate Inside The Room

6 Energy Distribution In Datacenter 6 Other Server Communication Storage 4% 4% Cooling 15% 38% 14% Server power 15% Processor 3% Switchgear UPS 5% Lighting 1% 1% PDU Cooling Load Is the Major Part Of The Power Consumption Major Heating Sources In Data Center Are Processors & Server Power

7 Optimize Air Management 7 Calculate The Critical Heat Load Depends The Equipment Deployed In The Room In Addition To The Heat Transferred From The Surrounding, Lighting And Other Sources Of Heat Estimate The Flow Requirement For Cooling The RLU Estimate The Power Density Based On RLU Cooling Rate Establish Room Cooling Strategy Based On The Space Availability And The Arrangements Of All The Ancillary Equipments In Addition To The Server Racks Determine The Cooling Methodology Based On Available Facility And The Easiness Heat Rejection And Cooling Redundancy Provide Redundancy To Meet Any Kind Of Emergency

8 Right Sizing Of The Datacenter 8 Fixed Losses Irrespective Of The IT Load There Are Losses Due To Physical Infrastructure Equipments Over Sizing Of Physical System Use Of Modular, Scalable Physical Infrastructure Have The Flexibility To Add When Additional IT Load Is Needed Better Prediction Of Future Need The Need Of The Future Expansion For The Organization Should Be Planned Properly Adaptable To New Technology The New Servers With More Heat Generation Should Also Be Considered Determine The Computing Source Required And Estimate The Capacity Depends On The Usage And Requirements

9 Solution Provided By Emerson 9

10 Layout Design 10 Air Management Strategy Plan The Air Flow Dynamics Based On The Load Raised Flooring/Overhead Space Insulate The Datacenter From The Direct Exposure To The Ambient Hot/Cold Aisle Separates The Hot And Cold Air Distribution System Positioning Of The Cooling System Better Temperature Control By Proper Position Perforated Tiles & Cabling Air Leakage And Thermal Insulation To Be Taken Care Precision Air-condition System Maintains The Sensible Heat, Tighter Temperature & Humidity Control

11 EDEC Data Center Layout 11 The Layout Is Arranged In Longitudinal Direction & Parallel To PEX Accommodate More Racks
