Not long ago data centers were concerned with maximum density and processing power.  But as electricity cost have risen and supply becoming a gating factor - the data center is changing .. 

" ... companies have become increasingly concerned over the state of the environment.... new generation of servers: machines that deliver more performance per watt and, perhaps to a lesser degree, are built in a more environmentally responsible manner. Hardware makers are stepping up to meet the challenge, "

" ... HP, ... a new line of ProLiant G6 servers that, claims the company, deliver twice the performance of the previous generation of ProLiant servers -- while using half the energy. ...  replacing servers purchased prior to 2006 with new HP ProLiant G6 servers, customers can slash their energy bills in half."

" ...HP is certainly not the only vendor touting the green credentials of its server hardware. ...  AMD and Intel are working furiously to make CPUs that are high on performance and low on energy consumption."

IBM and SU will create a liquid cooling system that will use double-effect absorption chillers to convert the exhaust heat from the microturbines into chilled water to cool the data center's servers, with sufficient excess cooling to handle the needs of an adjacent building. Server racks will incorporate IBM's Rear Door Heat eXchanger cooling doors that use chilled water to remove heat from each rack far more efficiently than conventional room-chilling methods. " ...

Keeping data centers colder than needed is not just expensive - it is wasteful of energy and contributes to global warming - and just might cause equipment to not last as long as possible ...  

" ... Albert Esser, vice president of datacentre infrastructure at ... Dell, ... datacentres could cut their energy bills by up to five per cent with no adverse impact on their servers' reliability by simply increasing the temperature of their server farms by five degrees."

"According to Dell, air being pumped into a datacentre can typically be as cold as 19 degrees centigrade, despite the fact that systems will remain reliable as long as the temperature is lower than 25 degrees centigrade."

Esser pointed to a recent datacentre rollout that Dell contributed to, where the temperature was kept at 19 degrees, resulting in a Power Usage Effectiveness (PUE) ratio for the datacentre of 1.8. This means that for every watt used to power the servers, 1.8 entered the datacentres. However, when the temperature was raised to 23 degrees the energy efficiency of the facility improved significantly, resulting in a PUE of 1.3.

" ... Google has recently presented papers that shows that disk drives do not fail more often at temperatures of 75 to 100 degrees Fahrenheit, while BT is on record as saying "all modern systems will operate effectively and reliably between five and 40 degrees Celsius"."

There's good news .... its getting easier to be green when buying a PC.

HP's new dx2250 with "Advanced Micro Device's Athlon chip and Cool 'n' Quiet technology" saves energy. 

One beta tester of HPs product - Snohomish County Public Utility District in Everett, Washington - found that these PCs were quieter and generated less heat.  They determined that they "could save about 20 Kilowatts per PC" by using the type of power-savings supply in the dx2250.  They are considering replacing 900 PCs so this equates to significant energy and dollar savings.

 The current focus on energy savings within the IT space has mostly focused on the data center where hardware density has been increasing resulting in increased demand for electricity and cooling capacity (additional electricity).  PCs are now becoming a target for energy savings.
 

Look for manufacturers to highlight their energy savings features in new PCs.  Shop wisely and you may be able to save both money and energy!

IBM's new Opteron processor-based servers can transform the data center by increasing performance while efficiently using power.  IBM has delivered a portfolio of technologies, called Cool Blue, to dramatically improve power utilization and reduce energy costs through tools for accurate planning and monitoring of power consumption to meet business expectations.  ...

...   "The new servers will deliver energy-smart business performance computing solutions that optimize power consumption at the chip, systems and software levels, and address clients' growing appetite for more powerful yet energy-efficient computing resources.  The portfolio of five new IBM systems and blades introduced is based on the next generation of AMD Opteron processors and is targeted to business performance computing -- a new compute model that leverages high performance computing capability to more effectively meet general business needs, such as business intelligence, enterprise resource planning and more.  The new systems join IBM's current line of AMD Opteron processor-based systems targeted for high-performance computing, first introduced to the market by IBM in April 2003, and can deliver up to 21 percent greater performance within the same power envelope as previous generations.  

IBM's industry-first, breakthrough software technology, IBM PowerExecutive. The software, available across IBM BladeCenter and System x servers at no additional charge, allows clients to meter actual power usage and heat emissions, and cap the amount of power used by a single server or group of servers at any given time.  IBM Director and Virtualization Engine can help provide a reduction in energy usage across systems through server consolidation and systems management virtualization technologies. By pooling, managing and optimizing IT resources across servers, virtualized systems can improve the economics and operations of under-utilized IT assets, effectively decreasing energy needs and usage by up to 40 percent. "   ...
