2 Objective / Agenda Broad overview of mission critical facilities and how they differ from commercial buildings. What are Mission Critical Facilities? Internal Components Air Distribution & CFD Modeling Uptime and Redundancy ASHRAE 90.1 & PUE Q&A throughout!

3 What is a Mission Critical Facility (of hardware or software) vital to the functioning of an organization. Any factor of a system (equipment, process, procedure, software, etc.) whose failure will result in the failure of business operations. That is, it is critical to the organization's "mission."

4 What is a Mission Critical Facility A facility that requires continuous operation 24x7x365. HVAC Power Security Controls Communications

5 What?

6 What a data center is NOT

7 Typical data center layout/components

8 Data Center Infrastructure Components RACK RACK RPP RPP RPP RPP

9 Utility Power

10 Data Center Infrastructure Components Data Suite NetPOP / Meet Me Room

11 Fiber Local / International

12 Data Center Infrastructure Components

13 Data Center Design Hot Aisle/Cold Aisle Layout Arranging servers to avoid mixing of server inlet and outlet air

14 Air Distribution Overhead

15 Air Distribution - Underfloor Tate Access Floors

16 Air Distribution - Underfloor Tate Access Floors

17 Data Center Design Containment Options Physical separation of airstreams to avoid mixing and achieve design return air temperature. Cabinet Chimneys Strip Curtains Deploy as Needed Low Leakage (Depends on Install) Hot Spot Reduction Rigid Frame & Panel Lowest Cost Higher Leakage Easy Install Higher Cost Low Leakage (Depends on Install)

18 Computational Fluid Dynamics

19 Data Center Design CFD Modeling Modeling of data center airflow to predict where issues will arise within cabinet layout. Validate design concepts Visually demonstrate simulated performance. Hot/Cold Aisle Layout w/o Ceiling Plenum Return Same Layout w/ Ceiling Plenum Return

20 Data Center Design Equipment Redundancy Data centers often have redundant equipment for concurrent maintainability. Example: Chiller Plant, Design Load = 1,200 tons, Using (3) 400 ton chillers Redundancy Level Min. # of Chillers Redundant Units N (No Redundancy) 3 0 N N N 3 3 Min. # of Chillers for Cooling Redundant Unit

21 Data Center Design Equipment Redundancy

22 Tier Classifications Active Capacity Components to Support IT Load Distribution Paths 1 1 Concurrently Maintainable Fault Tolerance (single event) Tier I Tier II Tier III Tier IV N N+1 N+1 1 Active and 1 Alternate N After any Failure 2 Simultaneously Active No No Yes Yes No No No Yes Compartmentalization No No No Yes Continuous Cooling Load Density Dependent Load Density Dependent Load Density Dependent Yes (Class A) Availability % % % % Annual Downtime (hrs.)

24 ASHRAE TC Recommended Temperatures

25 Thermal impact on equipment

26 ASHRAE 90.1 Economizer Requirements kw 175 kw

27 SPC 90.4P Energy Standard for Data Centers and Telecommunications Buildings. Proposed Standard authorized (San Antonio) 6/27/2012. Issued for advisory public review until 12/30/13. To establish the minimum energy efficiency requirements of Data Centers and Telecommunications Buildings, for: design, construction, and a plan for operation and maintenance, and utilization of on-site, renewable energy resources

28 Power Usage Effectiveness (PUE) THE GREEN GRID Avg PUE = 2.9 Avg IT load = 2.6 MW Total facility = 7.54 MW 20% report a PUE below MW 207k MT CO MW 60k MT CO 2
