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

• 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

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

2. Live migration must happen in same

cluster.

3. Each DC support 1024 clusters.

4. One cluster has 1024 nodes maximally.

1. Live migration time: shorter than 35

seconds.

2. Service broken time: shorter than 300

milliseconds.
