2 Agenda Background: US Green Building Council and LEED Overview LEED Certification for Electrical Infrastructure Improvement Top 10 Ways to Save Money in the Datacenter New generation Power Quality/Distribution Products for the High-Density Datacenter

3 Sustainability: a win-win approach The green movement is everywhere. But why? Buildings play a key role in our environment and in your bottom line. Cost savings (TCO) to users Government regulation and incentives Effective use of resources/ Social responsibility

4 What exactly is sustainability? There are many ways to define sustainability. Simply remember the three P s: People: the health and comfort of employees/users in your building: Social responsibility Planet: total health, environmental stewardship, reducing greenhouse gasses, making things lighter/smaller, recycling Profit: the financial advantage to keep the business healthy for the continued benefit of the People and Planet; Government incentives, regulations

7 The USGBC: An Overview The LEED Green Building Rating System is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED gives building owners and operators the tools they need to have an immediate and measurable impact on their buildings performance.

29 Where does all the energy go in the DC Total Energy Consumed at Power Station

30 A Very Expensive Space Heater BiCSi, Apr 08

31 Where is Datacenter Power Consumed Pay twice: For the power consumed And again to remove the heat. BiCSi, Apr 08

32 Save Energy Protect the Environment Data Points >50% of power entering a typical data center is used to cool the loads. A 1MW DC uses 177,000,000 KWhr over its 10 year life span. That power costs $17,000, at $.10/KWhr 1MW = 4300 cars worth of C cars worth is wasted due to poor design. DOE estimates 4M cars worth of C can be saved by 2015 with improved DC design. Equals the energy consumed by 1.8M US homes.

33 Save Energy Protect the Environment Datacenter Trends Consolidation Blade servers High-performance servers Increasing power and heat loads Increasing power densities Improvements in redundancy/availability Tier III/IV

34 Save Energy Protect the Environment Important Ways to Green in the Datacenter Turn Off, Virtualize and Consolidate Turn on CPU power management feature. Use IT equipment with high-efficiency power supplies. Use high-efficiency electrical infrastructure; Uninterruptible Power Supplies (UPS ), transformers etc. Adopt high-power distribution; 208Y to the enclosure. Adopt best practices for datacenter cooling. Conduct an energy audit of datacenter. Prioritize actions to reduce energy consumption.

35 The Legacy Datacenter Electrical Infrastructure Utility and Gen Set Switchgear UPS 480V PDU, xfmr, single and two pole circuits. 208/120V Whips and cable drops; 1/circuit.

36 Save Energy Protect the Environment Datacenter Infrastructure Efficiency Gains-UPS Traditional DC/facility designed with large/centralized UPS providing conditioned power to entire enterprise. Legacy systems ~90-94% efficient; sounds good right? Redundancy = 2 complete systems. Each side runs <50% load. Incremental efficiency improvements translate to big savings in electrical costs. 94% 60KW N+1 Assuming $.10/ KWhr >$6, annual savings

37 State of the Art UPS Technologies Increased reliability Improved electrical efficiency, input current harmonic distortion (THD) and power factor. Scalability- Hot Sync Redundancy Options- Inherent, N+1, 2N Installation/serviceability and testing

42 Save Energy Protect the Environment Legacy Power Distribution in DC Whips = 1 per circuit This Leads to this PDU resides on perimeter of DC floor or in utility room. Significant cabling runs required Double if loads are dual corded. Reduces air flow/cooling efficiency

43 Save Energy Protect the Environment Improved Distribution Scheme PDU powers PDR at end-row. One feed from PDU. MAC s are managed w/in the DC. Less cabling/cable management required. Improved cooling efficiency, fewer cables interfering with airflow. TP1 compliant Xfmrs can be installed. Improves efficiency 1-2% over entire loading range (30-50%) ROI realized w/in 6 years of deployment.

44 Save Energy Protect the Environment Improved Distribution Scheme: Dual Corded Loads Using 208/120V PDR Single and two pole circuits For dual corded loads Improves MAC s managed at the row-level.

45 High-Density Datacenter Power Distribution Using 208Y/120V Dual Input PDR Highly efficient use of space Configured w/ 8 panel boards poles ea. Rated A. 208Y/120 to the individual racks. Reduces total wiring by 25%. Simplified cabling improves air flow and cooling efficiency. Improves MAC s managed at the rack level.

46 Save Energy Protect the Environment PDU Benefits Improved electrical and cooling efficiency; TP1 xfmr/air flow. Smaller footprint; conserves valuable DC real estate. Greater flexibility; add panel boards or sub-feed; MAC s managed at the row. Requires fewer cables; shorter runs. Saves resources (less Cu), installation and materials costs. Improved manageability; comprehensive metering and monitoring available, branch circuit monitoring via Web IP/SNMP/Modbus TCP etc. Improved maintenance; front access reduces floor space required for service.
