Data center projects are burdened with these challenges and can benefit greatly from simplification and time savings. Schneider Electric s data center reference designs help customers optimize the planning process by providing them with validated, proven, and documented data center physical infrastructure designs. The use of these designs has a positive impact on not just the project itself, but also on the performance, reliability, and efficiency of the data center over its lifetime. eference Design 4 includes design information for three spaces: IT space, facility power, and facility cooling. Combined together, they comprise the integrated power, cooling and structural systems required to meet the design s specifications published in this overview document.

The architecture used in this electrical design is a dual path with 2(N+1) US and N+1 generators. Switching between generator power and utility is achieved using a programmable logic controller (LC). A 1600 amp bus feeds QED-2 electrical and mechanical switchboards. In the electrical room, USs are configured down-stream of the switchboards. Two Symmetra X units configured to 2(N+1) redundancy provide 225 kw of critical power to the IT room with 7 minutes of runtime. Valve regulated lead acid (VLA) batteries are housed in an isolated battery room. Two Galaxy 5000 US units configured to redundancy provide 36 kw of power to the pumps in the facility cooling system. Additional low-voltage transformers are included in the design to support lighting and other building loads. The power distribution architecture from the electrical room to the IT space utilizes a combination of LV panels and InfraStruxure power distribution units (DUs). The facility power system is designed to support additional peripheral devices like fire panels, access control systems, and environmental monitoring and control devices. ower meters in the electrical path monitor power quality and allow for predictive maintenance & diagnostics of the system. These meters also integrate with StruxureWare ower Monitoring Expert. Every component in this design is built and tested to the applicable ANSI, NEMA, UL or IEEE standards. Further design details and schematics are available in the engineering package. 1600A, 480V, 65kA FACILITY OWE BLOCK DIAGAM Utility AC 36 kw Galaxy SSW A, 480V, 65kA 2x CHW umps 500A, 480V, 65kA ackaged CAH 225 kw (N+1) SSW Symmetra X250 LOAD BANK 400A, 480V, 65kA Humidifier 3x DU Feeds to IT Space G G 1600A, 480V, 65kA 1600A, 480V, 65kA 500A, 480V, 65kA Utility AC 36 kw Galaxy SSW A, 480V, 65kA ackaged 2x CHW umps CAH 225 kw (N+1) SSW Symmetra X250 LOAD BANK 400A, 480V, 65kA Humidifier 3x DU Feeds to IT Space FACILITY OWE ATTIBUTES Name Value Unit Total amps (main bus) 1600 A Input voltage (main bus) 480 V Switchboard kaic 65 ka ower path Generator redundancy N+1 IT space US capacity 225 kw IT space US redundancy 2(N+1) IT space US rated load 7 minutes IT space US output voltage 480 V Facility cooling US capacity 36 kw Facility cooling US redundancy Facility cooling US rated load 9 minutes Document Number D04DS evision 1

The architecture consists of dual chilled water loops. The cooling system contains two 271 kw air-cooled, packaged chillers in a redundant configuration. Economization is achieved with a dry cooler to save energy during favorable outdoor conditions. In order to extend availability of chilled water during a power outage, redundant 3500 gallon water storage tanks provide 13 minutes of continuous cooling. DESIGN OTIONS This reference design can be modified as follows without a significant effect on the design s performance attributes: The piping architecture of the mechanical system feeds row-based Inow C CAHs in the IT space. It also feeds room-based CAHs in the electrical and battery rooms. More information on the cooling configuration is provided in the IT space section of this document. This design is instrumented to work with StruxureWare Cooling Monitoring Expert. Further design details such as dimensions, equipment placement, temperature set points, pipe sizing, flow rates, and pressure drops are available in the engineering package.

4 [eference Design 4] 4 IT Space DESIGN OTIONS This reference design can be modified as follows without a significant effect on the design s performance attributes: Add environmental and security management Change rack options (tall, wide, deep) Change power distribution options ack DU type (basic, switched) Add StruxureWare Data Center Expert The IT capacity of this design is 200 kw. The design is highly scalable and adaptable; it can be configured to support IT loads within a range. Smaller starting loads as low as 50 kw can be supported by making adjustments such as reducing the number of IT pods or decreasing the quantity of US modules. Likewise, this design can be used as a baseline for larger loads as high as 600 kw by using a step and repeat approach to the design. This flexibility drives efficiency and defers capital expenditure until needed. The IT space design specifies all of the physical infrastructure systems, as well as their physical arrangement/spacing, required to meet the overall design s performance attributes. This includes racks, DUs, rack power distribution, cooling units, and airflow management systems. Each pair of rows (pod) within the IT space can be stepped and repeated in a standardized and predictable manner. This enables right-sizing of power and cooling that scales with IT growth. Each pod supports an average power density of 5.8 kw per rack. All the pods are outfitted with integrated power and cooling distribution. Each pod is powered by floor mount factory-configured power distribution units (DUs). Every rack is configured with a metered rack-mount DU to enable remote monitoring of the units for efficiency and capacity management. Each pod is cooled by N+1 redundant chilled water-based Inow C CAHs that control the supply of cool air by monitoring temperature variation at the rack level. The security of the room is maintained at multiple points. At the rack level, access is controlled by a door lock and sensor. At the room level, security cameras are utilized for monitoring. ow A /A-1/ C C C C /A-2/ C/ /A-4/ C/ /A-6/ /A-7/ C/ /A-9/ /A-10/ C/ A-3/ A-5/ A-8/ A- /A-12/ IT OOM ATTIBUTES Name Value Unit IT load 200 kw ow B /B-2/ C C/ /B-3/ B-4/ C C C /B-5/ C/ /B-7/ /B-8/ C/ /B-10/ C/ /B-12/ B-6/ B-9/ B- /B-13/ Supply voltage to IT 120 / 208 V Average density 5.8 kw/rack ow C /C-1/ C C C C /C-2/ C/ /C-4/ C/ /C-6/ /C-7/ C/ /C-9/ /C-10/ C/ /C-12/ C-3/ C-5/ C-8/ C- Number of racks 34 racks IT floor space 1900 ft 2 ow D /D-2/ C C/ /D-3/ D-4/ C C C /D-5/ C/ /D-7/ /D-8/ C/ /D-10/ C/ /D-12/ D-6/ D-9/ D- /D-13/ Single or dual cord CAC/CAH type ow-based CAH CAC/CAH redundancy N+1 ow E /E-1/Z3 /E-2/Z3 /E-3/Z3 /E-4/Z3 C C/ E-5/ Z3 /E-6/Z3 /E-7/Z3 /E-8/Z3 /E-9/Z3 Containment type None Document Number D04DS evision 1

6 [eference Design 4] 6 Data center infrastructure management (DCIM) Good design and quality construction alone do not ensure a highly available & efficient data center. Data centers require on-going monitoring and management to ensure the facility lives up to its design intent. StruxureWare for Data Centers is a software management suite designed to collect and manage data about a data center s assets, resource use, and operational status throughout the life cycle of the facility. This information is then distributed, integrated, and applied in ways that help managers optimize the data center s performance and meet IT, business, and service-oriented goals. From IT assets to racks, rows, rooms and buildings, StruxureWare for Data Centers delivers the right information to the right users at the right time. Control level: Experts, on site or remotely, can control process performance and ensure business continuity in real time, while tracking energy consumption in a highly critical and secure environment. Operations level: Functional managers can optimize operations, energy, and assets through smart analytical tools, often spanning multiple sites. Enterprise level: C-level executives can drive their sustainability strategy efficiently, choosing the best scenario that meets their business objective to conserve enterprise-wide resources. StruxureWare for Data Centers allows for flexibility when requirements and implementation strategies change over time. StruxureWare software applications and suites simplify integration time, improve reliability, enhance visibility to energy information, and streamline operational efficiency.
