The impact of a system during the life Cycle
Carbon footprint for 10,000 subscribers during one year - Worst case scenario
ton
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.

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
