Energy efficiency is a lesson that the Japanese are excelling in. According to the International Energy Agency, Japan's power consumption as a percentage of gross domestic product is the lowest in the world.
Over 10 years have passed since the Kyoto Protocol was signed in Japan’s ancient capital city. Today, the country remains an environmental leader thanks to private sector innovation and the government’s extensive range of green reforms. Without any oil reserves to call their own, the Japanese – innovators by reputation – have pushed energy efficiency to the limit. For example, Japan is the world leader in solar panel technology, and both Toyota and Honda are selling ultra-efficient Hybrid cars.
Aside from the sense of national pride that many Japanese feel when helping their country lower its carbon emissions, businesses have realised that what’s good for the environment can also be good for their bottom line.
It’s now easier to select an energy efficient server
A new power measurement benchmark from the Standard Performance Evaluation Corporation (SPEC), launched in December 2007, will make it even simpler for both environmentalist and budget-conscious IT managers to lower both their power consumption and their power bill.
The SPEC is a not-for-profit organisation that creates performance benchmarks for hardware. It has worked closely with IT vendors including HP, Intel and Advanced Micro Devices, to develop software that helps potential buyers determine a server model’s energy efficiency levels. The new benchmark is the first to determine energy usage for particular workloads. This will help buyers to more accurately determine what the total cost of ownership is for competing server models.
Officially titled “SPECpower_ssj2008”, the new benchmark was created by a SPEC committee led by Klaus-Dieter Lange, a senior performance engineer at HP. Servers from HP are already using the benchmark’s Java-based application to measure their power consumption at capacity utilisation rates ranging from an idle state to 100 percent.
The measurement tool is just one of a range of solutions already integrated into HP products that can help organisations enhance performance and lower the cost of maintaining business-critical servers.
Unique HP efficiency
The latest HP BladeSystem servers use 49.7 percent less energy than traditional rack-based alternatives. They generate less heat from less power, and keep businesses cooler by pushing 31 to 60 percent less hot air back into your office environment.
With in-built instrumentation, accurate monitoring and control, and the ability to pool, share and allocate power and cooling to meet your demand, HP Thermal Logic means that HP blades won’t waste a watt of power or a gram of air.
HP Dynamic Power Saver reduces the power usage of HP blades by only using the power supplies your servers demand. It runs continuously in the background pooling power distribution to maintain system performance at higher application loads, and to provide power savings at lower application loads.
Furthermore, advanced solutions like HP Dynamic Smart Cooling (DSC) provide dynamic thermal management that controls a business’ cooling units based on heat levels, rather than chilling an entire building or data centre. DSC can help businesses reduce their cooling costs by 20 to 45 percent and significantly cut carbon emissions.
HP’s energy efficient solutions also extend to the extremely green StorageWorks portfolio. New enhanced disk storage systems and tape drives from HP can help you reduce power and cooling costs by as much as 50 percent.
Green is good for business
In the past helping the environment came at a cost to your business. Today, innovations like the new energy efficiency benchmark from the SPEC and other integrated solutions in HP products can help your company work smarter and sink your power bill. With benefits like these, being greener is an easy decision.
