[MISSING TEXT FROM ORIGINAL PUBLISHER]

[MISSING TEXT FROM ORIGINAL PUBLISHER] power grid are appearing. As an industry, we can't afford to overlook or avoid the suddenly critical task to implement a power supply strategy too much longer.

Does anyone know what the availability index (how many nines) your power source actually delivers and what it should become over the years ahead to meet the demand of your IT technologies and facilities? Strengthening mission-critical facilities along with an overall energy supply strategy is not an option. Consumption levels are higher and less predictable as the use of electricity for computing computing - computer  is soaring soaring: see flight; glider.

Estimates indicate that electricity accounts for nearly 40% of the overall energy consumption in the U.S. today. Many of those electrons are flowing into information technology devices. Even more interesting, the Internet is estimated to use 8% of the kWh output of the U.S. and another 5% of the kWh goes to support non-networked computers. This number projects to reach 50% of all electrical consumption in 2010 being used for information technology support. In summary, by the year 2010, electricity will account for half of the energy consumption in the U.S. and half of all electrical consumption will go for information devices!

Microprocessors consumed about 90 watts in 1995 and are expected to consume about 180 watts each in 2010. The consumption per microprocessor increases while the number of microprocessors in use exponentially ex·po·nen·tial

 grows. The net is obviously more and more electrical demand. To elaborate on this area, a study by Suhas V. Patankar, president of Innovative Research, and Roger R. Schmidt, Chief Thermal Architect for IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries)  presented at the 7x24 Exchange (http://www.7x24exchange.com) conference held recently in Phoenix provided many additional insights into power consumption trends.

The study provided projections of the heat loads per product footprint of various types of data processing data processing or information processing, operations (e.g., handling, merging, sorting, and computing) performed upon data in accordance with strictly defined procedures, such as recording and summarizing the financial transactions of a  equipment using watts/[ft.sup.2] as the primary measurement. As heat increases, reliability of computing equipment decreases. Teleprocessing ("long distance" processing) An early IBM term for data communications.  equipment topped the list by generating the largest heat load of the technology classifications sampled. Servers and disks ranked second followed by workstations. Tape storage systems ranked fourth as they generated the smallest heat load. Specifically their measurements revealed telecommunications Communicating information, including data, text, pictures, voice and video over long distance. See communications.  equipment generated a heat load of 2000 watts/[ft.sup.2], severs and disk generated 1000 watts/[ft.sup.2], workstations generated 200 watts/[ft.sup.2] while tape was at 100 watts/[ft.sup.2].

This excellent study also projected heat loads for each of these equipment types through the year 2010. The rank order of the equipment remained the same; however telecommunications technology increased more than the other areas. The server and disk storage systems grew faster in watts/[ft.sup.2] than did tape systems that ranked as the most energy-friendly of all four-technology groups measured in the study. By the year 2010, telecommunications gear will approach 10,000 watts/[ft.sup.2]. Servers and disk systems will approach 2000 watts/[ft.sup.2] while tape storage systems will consume nearly 200 watts/[ft.sup.2]. The study also assumes that there will be technology advancements during this period that will reduce the heat loads.

As we observe energy costs steadily rising and technology costs falling between 30-40% per year, storage demand increasing at over 60% annually, the key strategic question now becomes "when will IT energy costs exceed the costs of IT hardware?" These trends mean that we will begin to consider energy costs in the total cost of ownership. Given the higher costs of disk storage, storing less-active data on low energy consuming or removable storage systems will become increasingly important. The study also identified the typical allocation of heat loads within the data center by function. The breakdown attributed heat loads follows:

* Electrically active IT hardware: 30%

* Service clearances around products: 30%

* Site infrastructure and support equipment: 20%

* Main aisles and other inactive in·ac·tive

We are now spending billions of dollars annually in technologies that condition, move, and store electricity (electrons). Almost every market segment is moving up the demand curve for higher availability with the path to the "high nines" demanding a higher willingness to pay Willingness to pay (WTP) generally refers to the value of a good to a person as what they are willing to pay, sacrifice or exchange for it.

 for that quality of service. At least one of the energy control businesses now claims to be the "Seven Nines (three seconds of time per year without power) Reliability Provider".

Public power grids are realistically unable to deliver more than three or four nines of electrical quality because of various natural disasters and the physical exposure of the grid itself. Building the necessary energy reliability systems into your strategic path to the high nines will be a costly venture all predicated on the rising value of data. At what price does this model br eak? Obviously, this answer varies by business. Clearly, an ultra-clean power supply is the first step to achieving any level of "nines".
