In data center terminology, free cooling is the phrase used to describe a strategy for reducing energy consumption by leveraging the natural low air temperatures and cooler climates in some geographical regions. In this process, naturally occurring cold outside air is used inside the data center to aid the cooling process.
Leveraging cooler outside air uses less power than other cooling methods and can reduce or replace parts of mechanical refrigeration that requires high energy consumption to operate.
The free cooling process typically uses a mixture of outside air and air recirculation systems to cool air temperatures inside the data center by replacing or eliminating the compressor operation in air conditioning units or can be used to reduce the chiller operation for chilled water systems.
Data centers using free cooling systems use an economizer system — fluid and air economizers — to lower cooling system energy usage.
- Data Center Economizer
In data center terminology an air economizer is part of the data center cooling infrastructure. An air economizer can reduce data center power consumption by leveraging cooler outdoor air temperatures to cool the hardware and facility. In a typical scenario, air economizers draw in cool air from outside and expel hot air (generated inside the […]

- the iPhone 5
The fifth generation of Apple’s immensely popular iPhone mobile smartphone debuted in September 2012, supplanting the iPhone 4S as the company’s latest, greatest smartphone device. While the iPhone 5 offers numerous “under-the-hood” enhancements, the most noticeable change over previous-generation iPhones is the iPhone 5’s larger size (4″ display vs. 3.5″ in previous models), coupled with […]
An open source Linux operating system distribution developed and supported by the openSUSE Project. openSUSE is freely available for download, and the most recent “stable” release of openSUSE, openSUSE 12.2, debuted in September 2012 with new features like KDE 4.8, GNOME 3.4, GRUB 2 and XFCE 4.10. The openSUSE Project is sponsored by SUSE, which […]
- Software Defined Data Center - SDDC
SDDC is short for software-defined data center. May also be called software-defined datacenter (SDD) or virtual data center. Software-defined data center (SDDC) is the phrase used to refer to a data center where all infrastructure is virtualized and delivered as a service. Control of the data center is fully automated by software, meaning hardware configuration […]
