- 11. APC by Schneider Electric – Name – Date InfraStruXure™ for Data Centers Capacity Manager Product Design Benefits Rack elevations Easy to use rack front view enables accurate and detailed representation of equipment location Airflow analysis Locate new devices without overheating new or existing equipment by simulating changes in; supply temperature, airflow and number of cooling units Available capacity Understand available capacity by calculating actual space, power and cooling consumption against data center architecture constraints Physical equipment provisioning Quickly locate the optimum spot for that next server based on space, cooling and power needs Design analysis Model the effects of and compare alternative layouts through detailed design analysis Capacity Grouping Specify architecture capabilities to; match IT equipment with availability needs ad avoid stranded space, power and cooling capacity
- 12. APC by Schneider Electric – Name – Date InfraStruXure™ for Data Centers In-Row Cooling ● Cooling systems are placed within IT rows instead of at the room leve ● Inherently higher power density capability than room designs ● Fan power is reduced by 50% ● Needless dehumidification / rehumidification is eliminated (saving millions of gallons of water per year per MW). Hi ΔT is good! ● Need for high-bay areas and raised floors are reduced or eliminated (particularly for small installations) ● Cooling capacity can “follow” IT loads that move due to Virtualization / server power management ● Low mixing of Cool Air back into CRAC w/ Low ΔT! Electrical savings possibility: 7-15% For new designs; Exceptional for high density designs
- 13. APC by Schneider Electric – Name – Date InfraStruXure™ for Data Centers Room Row Rack Cooling Architectures ● The two main cooling equipment functions are to… ● Provide the bulk cooling capacity ● Distribute the air to the IT loads ● The major difference in architectures lies in how they perform the second task. ● Airflow is crudely constrained by room design, is not visible in implementation, and varies considerably between installations. Floor plans showing the basic concept of room, row, and rack-oriented cooling architecture.
- 14. APC by Schneider Electric – Name – Date InfraStruXure™ for Data Centers Benefits Comparison of Cooling Architectures Summary and Analysis The modular rack-oriented architecture is the most flexible, fast to implement, and achieves extreme density, but at the cost of additional expense. Room-oriented architecture is inflexible, time consuming to implement, and performs poorly at higher density, but has cost and simplicity advantages at lower density. The modular row-oriented architecture provides many of the flexibility, speed, and density advantages of the rack-oriented approach, but with cost similar to the room-oriented architecture.
- 15. APC by Schneider Electric – Name – Date InfraStruXure™ for Data Centers Electrical Efficiency Rack-oriented Architecture Lower electrical costs Room-oriented Architecture Lower electrical costs with low power densities, but dramatically increase with rising densities Air needs to travel more distance Power consumed by unit to mix air Row-oriented Architecture Lower electrical costs with higher power densities Closely coupled with heat load Usable capacity sustained
- 16. APC by Schneider Electric – Name – Date InfraStruXure™ for Data Centers Water or Other Heat Transport Piping Concern: Leakage due to water or refrigerant piping being located with IT equipment, causing leaks and therefore downtime. Solution: Advances in piping technology dramatically reduced chance of leakage and improved reliability. See APC White Paper 131 for more information.
