A global approach for a
Sustainable ICT
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential
The Challenge • Reduce the energy consumption to
reduce the impact on climate change.
• Give the possibility to use ICT service
everywhere to every one
Page 2
• Standard on equipment power/energy
consumption
• Standard on impact of equipment
System (LCA… Methodology etc.)
The Solution • Efficient solution for ICT and Simple
system dedicate to rural areas

Clearly the major impact is
during the use of the
network
The energy used to give
a service is more than
50% of the total impact.

L2 mode can reduce power consumption
by 30%~40%
L3 model can reduce power consumption
nearly to 0. But still under
standardization because the crosstalk
problems
L2 mode implementation can save about 11.7 kWh for day for equipment (1024 ports)

Dynamic DC management to avoid hot spot
In the DC Facility, the node in area possess different cooling condition.
VM can be moved from the PM of heat hotspot, result in balanced cooling level and higher
working temperature, thus lower PUE
When all VM of certain PM being moved to other PM (without hotspot), that PM can be power
off to improve the power efficiency.
Temperature in a data center is NOT balanced

Project Plan
2009.10: 400 staff on trial
2010.5: officially 8K R&D staff at Shanghai center are
moved to virtual desktop
2011 & beyond: move all 60K R&D staff around the globe
from PC to virtual desktop
