Projects are often utilized as a Meaning of achieving’s strategic plan. Project typically authorized as a result of one more of the following strategic Consideration.
- Market On demand
- Strategic Opportunity
- Customer Request
- Technological advance
- Legal Requirement's
Organization manages portfolios based on their Strategic Plan, which may dictate the hierarchy to the portfolio,program and project Involved.
well i am posting a simple diagram which actually help you to understand every thing at once
if you would have read about the Previous Articles about the project & Program
Portfolio : Portfolio is general terms that used for to define the complete wing of any product or any operating model. Certainly yes.
Portfolio is combination of multiple Programs and Project which are individual or interlinked with a defined Scheduled time , Quality and Budget . it could be a whole product or Customer facing Service.
you might have read about “what is project “ – again lets put it Simple agian
A set of Project’s which are interlinked or Individual to each other which needed to delivered in time,Budget and with defined quality. Multiple set of project called as Program.
lets be simple – Project is a set of deliverables which need to be delivered in time,in budget,with high quality by following all necessary compliances .
Protection from power loss is a common characteristic of datacenter facilities. Such protection comes at a significant first cost price, and also carries a continuous power usage cost that can be reduced through careful design and selection.
Objective 1: Design UPS system for efficiency. The electrical design impacts the load on and the ultimate efficiency achieved by the UPS. (See chart illustrating typical power flows in data centers.) Strategies: Maximize Unit Loading. When using battery based UPSs, design the system to maximize the load factor on operating UPSs. Use of multiple smaller units can provide the same level of redundancy while still maintaining higher load factors, where UPS systems operate most efficiently.
Metric: Average UPS loading. Battery based UPSs should be loaded to 50% or greater in actual operation.
Objective 2: Select most efficient UPS possible. UPS efficiencies vary, not only across different types of topographies, but also within the same type of system between different models. Strategies: Specify Minimum Unit Efficiency at Expected Load Points. There are a wide variety of UPSs offered by a number of manufacturers at a wide range of efficiencies. Include minimum efficiencies at a number of typical load points when specifying UPSs. Compare offerings from a number of vendors to determine the best efficiency option for a given UPS topography and feature set.
Evaluate UPS Technologies for Most Efficient. New UPS technologies that offer the potential for higher efficiencies and lower maintenance costs are in the process of being commercialized. Consider the use of systems such as flywheel or fuel cell UPSs when searching for efficient UPS options.
Do Not Overspecify Power Conditioning Requirements. In general, the greater the level of power conditioning used, the lower the system efficiency. Consider line-reactive UPSs for standard server equipment that does not require the higher level of power conditioning offered by double-conversion units. Some manufacturers offer UPS systems that can operate in both single and double conversion mode, allowing for flexibility to deal with unanticipated future equipment or power conditions. Do not use additional power conditioning in the PDU if it is not required.
Metric: UPS Efficiency. UPS efficiency should exceed 90% at full load and 86% at half load. See chart for range of UPS found on the market today.
Objective 3: Use self-generation for large installation. For large facilities, a self-generation plant designed to capture and utilize waste heat can achieve very high total efficiency as well as offering great control over power reliability and quality. Strategies: Eliminate Standby Generator. Standby generators are typically specified with jacket and oil warmers that use electricity to maintain the system in standby at all times, so even if (especially if) they are never used they are a constant energy waste. Eliminate of a standby generator requires proper engineering of the system, but will reduce energy use as well as save first and maintenance costs. Standby generator heaters (many operating hours) use more electricity than the generator will ever produce (few operating hours).
Recover Waste Heat for Local Heating Uses. If the datacenter is physically near a commercial or industrial heat load, use the waste heat directly to serve the load. Use of the waste heat directly for heating is the most efficient way to optimize total self-generation system fuel efficiency.
Recover Waste Heat for Datacenter Cooling Use. Waste heat can be used to drive absorption or adsorption chillers, maximizing the utilization of the fuel used to power the generator system.
Eliminate UPS Systems. With careful design, UPS systems can be replaced by self-generation equipment. Combined with recovering waste heat, such a system combines high efficiency with no UPS efficiency losses.
Metric: Utilized Electricity and Heat / Input Fuel Btus Include electricity use and legitimate uses of waste heat. Include electricity use and legitimate uses of waste heat.
The IT equipment is the reason for the facility. Increasingly, there are reasonable opportunities to increase the efficiency of IT equipment, reducing the need for mechanical infrastructure and ongoing energy use directly at the load level through the selection of IT equipment.

bjective 1: Specify efficient server equipment. Reducing the energy use of the load, IT equipment, directly is possible and has multiple cost savings — lower total infrastructure requirements, lower cooling loads, lower electricity consumption, smaller UPS, etc. Strategies: Specify High Efficiency Power Supplies. Server power supplies can be made significantly more efficient than currently offered. Specify power supplies that have a minimum efficiency equal to or greater than the minimum recommended power supply efficiency guidelines put forth by the industry group Server System Infrastructure (SSI) Initiative.
Consider Equipment Power Consumption in Specifications. Develop internal procedures to encourage the acquisition of the most energy efficient equipment that will meet the application requirements. Lower power consumption chips, idle mode setbacks and other features can vary the power efficiency of equivalent equipment. Reference: new chips from SUn
Metric: Power Supply Efficiency. Power supplies in IT equipment should be better than 80% efficient from 20% through full load.
Objective 2: Use cooled equipment racks. Incorporating waste heat rejection directly into the IT equipment racks can allow for it to be collected and rejected very efficiently. Strategies: Use Equipment Racks with Integral Coil. Transferring IT equipment waste heat to a cooling water loop directly at the rack allows for the complete elimination of heat recirculation. The heat is captured prior to mixing with the room air at a higher air temperature. This allows a correspondingly higher cooling water temperature to be used in the cool, allowing significant plant efficiency opportunities. Since IT equipment heat is removed prior to it being mixed into the room air, a much smaller room conditioning system can be used — a standard office system with the addition of humidity control and enough capacity to cool racks that are open for servicing can be used.
Consider Direct Liquid Cooling. Direct liquid cooling options range from the mature technology of providing water passages through chip heatsinks to new approaches under development, ranging from using heatpipes to conduct heat from a chip to a liquid reservoir to spraying whole boards directly with an inert dielectric cooling fluid. Direct liquid cooling is far more efficient than using air cooling, which requires about 3,500 times the volume to remove the same quantity of heat. Where direct liquid cooling options are offered, they should be carefully considered for their significant fan power savings and synergy with medium temperature chilled water loops and waterside economizer free cooling.

Metric: Watts cooling device / rack Watts cooled. The combine wattage of all fans (including small, in-rack fans) and pumps utilized by the liquid cooled rack to transfer heat to the chilled water loop divided by the actual watts of rack cooled should be less than 0.202 (0.71 watts per ton of delivered cooling).
