8. The convergence of liquid cooling
and air cooling; more indirect
evaporative cooling and less chilled
water cooling
GPU and NPU applications generate more
high-density scenarios and liquid cooling
systems will become more and more popular.
Some storage and computing services,
however, are still in low-density scenarios.
To quickly adapt to uncertain IT service
requirements in the future, the cooling solution
must be compatible with the air-cooling
system and liquid cooling system. In addition,
the complex architecture of the chilled watercooling
system hinders quick deployment and
easy O&M. An indirect evaporative cooling
system, with a modular architecture, will
shorten the deployment time and simplifies
O&M. In addition, by fully utilising the natural
cooling resources, power consumption of the
cooling system will be greatly reduced. In
areas with a suitable climate, the chilled water
system will gradually be replaced by indirect
evaporative cooling system.
9. Dynamic linkage between bits
and watts
“
TO MEET THIS DEMAND,
DATA CENTRES MUST SOLVE
CONSTRUCTION CHALLENGES TO
BUILD AT SPEED AND SCALE AND
MANAGE ENERGY USAGE AND COSTS
IN A SUSTAINABLE WAY.
Reducing PUE doesn’t mean that the
overall energy consumption of the data
centre is optimal. Instead of focusing on
the data centre energy facilities, the energy
consumption of the data centre needs to
be evaluated and optimised as a whole.
Through full-stack innovation among facility,
IT, chipsets, data and cloud, bits and watts
will work collaboratively to achieve dynamic
energy-saving and optimal energy efficiency
of the entire system.
10. Trustworthiness
architecture modularisation and equipment
room modularisation, finally achieving full
modularisation of the data centre. The full
modular design will enable fast deployment,
flexible capacity expansion, simple O&M and
high energy efficiency.
7. Simplified power supply
architecture. Lithium batteries
becoming the norm
The power supply and distribution system
of a traditional data centre is complex and
fragmented; it occupies a large footprint
and it is difficult to locate faults. A simplified
power supply architecture will reduce
power conversion times, shorten the power
supply distance and footprint, improve the
space utilisation rate and enhance system
energy efficiency. Compared with lead-acid
batteries, lithium batteries have advantages
in terms of footprint and service life. As the
cost of lithium batteries decreases, lithium
batteries will be widely used in data centres
in the future.
(Full modularisation of the data centre
will enable fast deployment, flexible
capacity expansion, simple O&M and high
energy efficiency.)
As the data centre facility becomes more
intelligent, the network security threats
will multiply. The data centre must have
six features: resilience, security, privacy,
safety, reliability and availability to prevent
attacks and threats from environments
and malicious personnel, including network
intrusion threats.
(Reducing PUE doesn’t mean that the
overall energy consumption of the data
centre is optimal. Instead of focusing on
the data centre energy facilities, the energy
consumption of the data centre needs to be
evaluated and optimised as a whole.) •
