Technologies Behind NEC’s High Temperature Ambient Server
5. Lineup
The Express5800 series of x86 servers supporting ambient operating
temperature of 40°C includes a wide variety of models such as a product
for data center providers that use a large number of servers and a tower
server ideal for offices, shops, and other smaller-scale applications.

Eco-Friendly Data Center
NEC has launched an Eco-Friendly Data Center project to promote power efficiency in
data centers. The goal of this project is to implement power savings in facilities as a
whole by reducing the power consumption of not only ICT equipment but also the
cooling system and other equipment, as well as to promote eco-friendly data center
construction and facilities management.
The Eco-Friendly Data Center project supports data center power savings by providing
consulting services, ICT equipment, and facilities solutions. The consulting services
aim to visualize and highlight current problems in the data center from every viewpoint
and propose measures to achieve appropriate goals. The ICT equipment comes in the
form of the High Temperature Ambient Express5800 series, NEC Storage M series, and
power saving control software applications. The facilities solutions involve facility
monitoring and other solutions to improve cooling efficiency.

HTA servers also useful for offices and shops
Power saving is required in many locations other than data centers. Even without the order
to limit the use of electricity issued by Japanese government in 2011, awareness has been
high concerning the need to save power in offices and shops. The Express5800 series of
x86 servers supporting ambient operating temperature of 40°C can be used to conserve
power in these places.
When servers whose maximum ambient operating temperature is 35°C are installed in an
office, there is no choice but to set the cooling system to a lower temperature.
Implementing a model supporting ambient operating temperature of 40°C allows you to
set the cooling system to a higher temperature, significantly reducing power consumption.
According to a document published by the Agency for Natural Resources and Energy of
Japan, increasing the office temperature by 2°C reduces cooling system power
consumption by approximately 8%.
6. Conclusion
This white paper describes a design concept developed by NEC to improve
the cooling ef ficiency of HTA ser vers and storage devices, and
demonstrates that cooling system power consumption, which accounts for
approximately 30% of the power consumed in data centers, can be
reduced by implementing these servers and storage devices. This white
paper also provides examples of verifications tests confirming that stability
can be maintained by only using a direct free air cooling method and that
the servers and storage devices can operate for a long period of time even
in a high temperature environment.

As we shift to cloud computing, data centers are becoming increasingly
important. The HTA servers and storage devices from NEC support
enterprises who want to promote environmental friendliness in their data
centers and IDC providers who want to provide high-quality, inexpensive
data center services.

Increasing the ambient temperature in the office by 2°C reduces
cooling system power consumption by approximately 8%.
