EFFICIENCY –MACRO LOOK
LESS EFFICIENT SYSTEMS
OPTIMISED EFFICIENT SYSTEMS
IT IS OUR RESPONISIBLITY TO CREATE & OPERATE HIGHER EFFICIENT SYSTEMS TO BE
IN BUISENSS AS WELL AS TO REDUCE IMPACT ON ENVIRONMENT
DATA CENTER – POWER DISTRIBUTION
Case for need
LIGHTING POWER, 0.8%
Misc POWER, 1.0%
UPS COOLING POWER, 3%
BLOWER INPUT POWER,
6%
All Power Measured in KW
COOLING INPUT POWER,
22%
UPS INPUT POWER, 68%
Power Usage Effectiveness (PUE) =
Total Power
Total Server Power
Datacenter Infrastructure Efficiency (DCiE) =
UPS Electrical Power -68%
Cooling Power

CHANGING
• The system efficiency depends on Technology available at the point of time of project execution.
•Total Cost of Owner ship is not completely thought of.
• Knowledge of availability of efficient products in the market
• Known devil is better than a angle
• Increased Components compared to normal Electrical Systems due to CAPACITY, RELIABILITY, AVIABILITY requirements
• The replacement cost of equipment is huge
• No standards for ground level tweaking for better efficiency.
ONLY CONSERVATION IS CONSTANT AND POSITIVE
WHAT WE LEARNT
Procure & Operate Single operating Voltage System
Xfrmer
Maintaining single operating voltage reduces unnecessary voltage
conversions, regulation losses
G
Operate at higher voltage level at Server Input
Operate at higher voltage level at Server Input reduces the
current requirement, this will reduces the losses.
415V
Max Voltage (90-260VAC)
Nominal Voltage (100-240VAC)

TYPICAL ELELCTRICAL SYSTEM
Concentrate on the component which directly impact your Energy Consumption
WHAT WE LEARNT
Evaluate your Devices used in Datacenter for Energy consumption
Evaluate devices planned to use in Data center for power , cooling, environmental requirements.
This will help us to choose between similar capable devices in terms of energy consumption and hence
reduce your power consumption.
TEST before you USE ( Get best out of customers)
