1. The real challenge in Data Center

2. The data center real challenge is not the
individual discipline and parts on it but the
opposing effect of each it has onto one
another - which needs to be monitored and
controlled

3. Trade mark of Traditional Data Center
1. poor efficiency till the room is full
2. "for long term use" design - poor capex
investment
3. too many risk involved
a. technology change
b. air flow management strategy
c. water distribution

Max. Draw Power = Breaker Power * 80% Max. Actual Usage = Breaker Power * 50%

8. Capacity Management
• Optimize Use
– Reduce the gap between the actual usage and
design
• Right-Size
– Reduce the gap between the supply and demand

9. Relationship of Availability to Efficiency
Availability
As you increase the service availability
the efficiency of the Data Center drops
since more equipment needs to be powered
up and cool down for the same number of service.
The density of equipment also affect the way the
Data Center is being cooled down.
