Why 1% Efficiency Matters

Critical Power May 14^th, 2014

(2)

• Why efficiency gains of as little as 1 percent for power equipment can significantly impact data center total cost of ownership (TCO).

• TCO metrics for a typical 10 megawatt data center and why a TCO model shouldn’t be abandoned at the power system

component selection phase.

• How data center managers can align CapEx centric purchasing teams with OpEx centric operational teams.

Key Questions / Problems Addressed:

The Case for Focusing on Energy Efficiency

(4)

• Sum of Capital Expenditures (CapEx) and Operational Expenditures (OpEx)

• Critical metric for determining true long-term cost

• Lowest purchase price does not necessarily reflect the lowest cost

• Not using TCO in purchasing high power equipment decisions could cost millions of dollars

TCO, Defined

And this translates to…

CapEx

• UPS System Cost

OpEx

• Maintenance

• Maintenance Contract

• Battery Replacement

• Fan Replacement

• Capacitor Replacement

Energy Costs

• UPS Losses

• Cooling Energy

• Total Losses KW

• Total Losses KWH

• Total Energy Cost

TOTAL UPS TCO

Evaluating TCO: Real World Results

Entry Descriptions Car Buying Scenario #1 Car Buying Scenario #2

Tax, license, extended warranty costs $2,522.50 $2,522.50

Depreciation costs $19,500.00 $19,500.00

Finance costs $5,230.00 $5,230.00

Insurance costs $4,250.00 $4,250.00

Fuel costs $17,722.22 $11,392.86

Maintenance & repair costs $2,100.00 $2,100.00

Total cost of buying and owning the car $51,324.72 $44,995.36

Annual cost to own and operate

vehicle $10,264.94 $8,999.07

Monthly cost to own and operate

vehicle $855.41 $749.92

Car cost per mile $0.51 $0.45

18 MPG Vehicle

Fuel cost increases to over

$51,650 or 2X purchase price

28 MPG Vehicle

Fuel cost increases to over $34,150 or

$10K higher than the purchase price

What if gas was 3X today’s price?

This may seem far fetched for an automobile, but the energy cost

for a UPS module can exceed the module purchase price in as little as 3 years.

Challenge

Upgrade a 30,000 square-foot Dallas data center by replacing 230 separate single phase uninterruptable power supplies (UPS) to improve power quality and boost managed hosting uptime.

Solution

A GE three phase UPS system provides both critical backup and clean and consistent power, dramatically managing power anomalies that affect server performance and downtime.

Benefit

CoreSpace is realizing more than $88,000 a year in energy and cooling cost savings.
