I have posted about the new tower server Primergy TX120 from Fujitsu Siemens Computers that is said to be the world’s most energy efficient server. Not everyone can afford to buy a server, so here is something for us more ordinary bloggers.

Western Digital, one of the most well known hard drive companies, has teamed up with Kanguru in marketing a green hard drive for consumers and businesses. These GreenPower Hard Drives are all internal drives which are available in capacities from 320GB and up to 1TB (1000 GB).

Western Digital claims that these new GreenPower Hard Drives is saving up to 40% in power consumption. Western Digital says they accomplish this through several technologies such as balancing spin speed, transfer rate and cache size; automatically unloading the heads during idle to reduce aerodynamic drag and calculating optimum seek speeds.

These new GreenPower Hard Drives goal is to be “Energy Star 4.0” compliant. That means a minimizing their carbon footprint while realizing savings in electricity costs.

According to Western Digital data-centres that use “10,000 drives can save $100,000 in annual energy costs, and reduce CO2 emission by 600 metric tons”.

Also, don’t forget to check out Kangurus eco-friendly hard drives. These eco-friendly hard drives have three power modes that allow you to save up to 75% on the energy usage. The drives are fully RoHS compliant (no hazardous substances).

Fujitsu Siemens Computers says that their brand new tower server Primergy TX120 is the most energy efficient server in the world. Primergy TX120 is said to consume 40% less energy than conventional tower servers. The Primergy TX120 is also one-third the size and makes half the noise (producing 28dB while idling and 31dB in operation).

TX120 uses a redesigned heat pipe air cooling system. Although previous systems have used heat pipe cooling, reducing the size of the unit required a new component alignment strategy. In the TX120 all heat producing components, CPU, chipsets, etc, are strictly aligned along a linear heat pipe. Two small temperature controlled fans also sit either side of the pipe in a push-pull arrangement. Another benefit of the heat pipe is it enables the user to choose either vertical or horizontal server installation. Unlike water cooling used in some small servers, heat pipe provides similar quiet operation, requires fewer components, and with no potential leakage problems is more reliable.

According to Fujitsu Siemens Computers the use of TX120 instead of a larger tower server can reduce CO2 emissions by the equivalent of planting 31 cedar trees per year.
