5 Today's agenda UPS designs Reliability and Availability Types of redundancy Improving redundancy Options for power distribution flexibility Energy efficient designs Additional considerations Closing 5 5

6 Do you find yourself asking: What makes the best sense for me? How much redundancy do I need? What is the best approach to save money? How much is this going to cost? 6 6

8 Reliability vs. Availability Reliability is many times expressed as the products expected operational time before it quits operating properly MTBF Mean Time Before Failure MIL-HDBK-217F Telcordia (Bellcore) SR-332 MTBF is NOT a good measure of performance Availability is a better measure MTBF Availability = MTBF + MTTR MTTR = Mean time to repair Availability is usually expressed by the number of 9 s 8 8

9 Types of redundancy - improving availability No redundancy Subsystem redundancy Parallel redundancy (N+1) redundancy (2N) redundancy (2N+1) redundancy 9 9

17 Subsystem redundancy Redundancy in electronics Some designs may include some redundant internal components, but still contain a number of sub systems that are common. Subsystem B λ 2 INPUT Subsystem A λ 1 Subsystem B λ 2 Subsystem C λ 3 Subsystem D λ 4 OUTPUT Subsystem B λ

18 Parallel redundancy Parallel Redundant systems. The highest level of redundancy, because there are no, or very simple redundant components, which have a minimal impact to overall reliability. These systems should also have peer to peer control capability, as then a control issue in one system will not impact another. Subsystem A λ 1 INPUT Subsystem A λ 1 Subsystem A OUTPUT λ

40 The Value of Eaton Eaton Three-Phase UPSs provide the greatest combination of benefits, delivering tangible benefits for specifying engineers, consultants and end users» Lowest Total Cost of Ownership industry-wide» Superior Performance and efficiency» Real-time Information and Control» World-class Support and Service 40 Eaton

41 Low TCO Low TCO Improving the bottom line Eaton UPSs deliver low TCO from advances in several product facets» 400V Site Design» High Power Density small system footprints» Reduced weight and transportation costs» Low installation and Leading Efficiency Quantifiable Benefits» Maintenance» Scalability 41 41

42 UPS Efficiency over time 42 42

43 Low TCO Leading Efficiency Two complementary Eaton-proprietary technologies, maximizing UPS efficiency under any condition! Variable Module Management System (VMMS)» Maximized efficiency in double conversion mode» Both in single- and multi-ups systems applications Energy Saver Systems (ESS)» The ultimate savings: 99% efficiency» Automatic fast transfer to double conversion mode when needed (in less than 2 ms) Energy Advantage Architecture Higher System Efficiency No Compromise On Reliability 43 43

44 Low TCO Leading Efficiency Energy costs are overwhelming equipment costs in data centers.» UPS electrical losses account for 5-10% of the overall electrical expenditure.* Eaton s Energy Saver System drives these losses down to nearly zero. The energy savings recovers the cost of the UPS in less than 5 years. * Underlying figures from The Invisible Crisis in the Data Center: The Economic Meltdown of Moore s Law, Uptime Institute,

45 Low TCO Leading Efficiency ESS Efficiency 99% across the complete operating range 45 45

46 Low TCO Leading Efficiency The energy savings from ESS typically recovers 100% of the UPS cost over a 3-5 year period» At 250kW of critical load, the savings is equivalent to $4000 per year per point of efficiency gain. Backing up your 250kW load with an ESS UPS is equivalent to pulling 29 cars off the road

47 Low TCO Leading Efficiency How to maximize efficiency with lighter loads in double conversion mode, especially in multi-ups and redundant system configurations? Solution #1: Concentrate load on certain UPS s to maximize UPS load level and overall system efficiency» Some energy savings Limited to multiple-ups systems (with several UPS in parallel) Still not optimal Solution #2: Eaton 9395 and its Variable Module Management System» Automatically optimize efficiency at UPM level Concentrate the load on certain UPM s to maximize overall system efficiency» Only possible thanks to modularity of Eaton 9395 UPS Not limited to multiple-ups systems Achieve even higher optimization thanks to UPM s modularity 47 47

48 Low TCO Leading Efficiency Example with same load applied to different multi-ups configurations 48 48

50 Low TCO 400V Site Design 480V AC» Losses through the UPS, isolation transformer/pdu, and server equipment» End-to-end efficiency of approximately 76% 50 50

51 Low TCO 400V Site Design 600V AC» Used primarily in Canada» Can provide small savings in equipment costs, and utilizes lower currents» Requires multiple isolation transformer-based PDUs» End-to-end efficiency of approximately 76% 51 51

52 Low TCO 400V Site Design 400V AC» Commonly used throughout the world» PDU isolation transformers eliminated» End-to-end efficiency of approximately 80% 52 52
