A Quantitative Comparison of High Efficiency AC vs. DC Power Distribution for Data Centers
Source: APC by Schneider Electric This paper presents a detailed quantitative efficiency comparison between the most efficient DC and AC power distribution methods, including an analysis of the effects of power distribution efficiency on the cooling power requirement and on total electrical consumption. The latest high efficiency AC and DC power distribution architectures are shown to have virtually the same efficiency, suggesting that a move to a DC-based architecture is unwarranted on the basis of efficiency.

Eco-mode: Benefits and Risks of Energy-saving Modes of UPS Operation
Source: APC by Schneider Electric Many newer uninterruptible power supplies (UPS) systems have an energy-saving operating mode known as “eco-mode” or by some other descriptor. Nevertheless, surveys show that few data centers actually use this mode, because of the known or anticipated side effects. Unfortunately, the marketing materials for these operating modes do not adequately explain the cost/benefit tradeoffs. This paper shows that eco-mode provides a reduction of approximately 2% in data center energy consumption and explains the various limitations and concerns that arise from eco-mode use. Situations where these operating modes are recommended and contraindicated are also described. Read More...
Economizer Modes of Data Center Cooling Systems
Source: APC by Schneider Electric In certain climates, some cooling systems can save over 70% in annual cooling energy costs by operating in economizer mode, corresponding to over 15% reduction in annualized Power Usage Effectiveness (PUE). However, there are at least 17 different types of economizer modes with imprecise industry definitions, making it difficult to compare, select, or specify them. This paper provides terminology and definitions for the various types of economizer modes and compares their performance against key data center attributes. Read More...
How Data Center Infrastructure Management Software Improves Planning and Cuts Operational Costs
Source: APC by Schneider Electric Business executives are challenging their IT staffs to convert data centers from cost centers into producers of business value. Data centers can make a significant impact to the bottom line by enabling the business to respond more quickly to market demands. This paper demonstrates, through a series of examples, how data center infrastructure management (DCIM) software tools can simplify operational processes, cut costs, and speed up information delivery.

Classification of Data Center Infrastructure Management (DCIM) Tools
Source: APC by Schneider Electric Data centers today lack a formal system for classifying infrastructure management tools. As a result, confusion exists regarding which management systems are necessary and which are optional for secure and efficient data center operation. This paper divides the realm of data center management tools into four distinct subsets and compares the primary and secondary functions of key subsystems within these subsets. With a classification system in place, data center professionals can begin to determine which physical infrastructure management tools they need—and don’t need—to operate their data centers.

David vs. Goliath? Talent Management Outlook in Midsized vs. Large Organizations
Source: Cornerstone OnDemand Many surveys address how the needs of human resources (HR) vary, but they often focus on the difference between small and large organizations with the assumption that midsized organizations are similar enough to large organizations not to require extra focus. To get a different perspective, we looked specifically at how the HR function in midsized organizations compares to their much larger counterparts. Are they as similar as is popularly believed?
