Agenda
• Business Validation & Justification of New
Capacity
• What’s right-sizing?
• Financial impact of right sizing – both on Capex
and Opex
• Stranded Capacity: Can you use it?
• Sustainability & Efficiency
• Conclusion

Summary
Data center requirements,
based on IT utilization
efficiency
1.Validating business
requirements
2.Right sizing opportunities
3.New build avoidance by
audit and recovery of
existing space and
capacities

Why is business validation important?
• Financial savings
• Efficiency in design & operation
• Sustainable practices
Industry has high focus on efficiency. But what is
efficiency?
5
Validating Business Requirements & Right Sizing
Criticality Location
Higher tiered electrical
design?
Location criteria
UPS + Generator? Cost of utilities
Is there an uptime
requirement?
Climate condition factors
Utility incentive rebates
What are the impacts of
an outage?
Labor Market
What do you validate for?
6
Validating Business Requirements & Right Sizing
Density Space
Per rack density
validation
Can you use existing
space?
Cost impact between
design densities
Can you use stranded
capacity?
Have you benchmarked
your existing footprints
Tech refresh and
consolidation
What do you validate for?

Cost Savings through Right Sizing
Example using the Uptime Institute Cost Model:
Business requirement for 500 racks per 8kW rack
average, with UPS+Generator backed Tier III design.
Density (kW) Total Racks
Total Power (kW) Tier II Tier III
8 500 4000 $ 50,000,000 $ 100,000,000
6 500 3000 $ 37,500,000 $ 75,000,000
Capex Model:
Tier I $11,500
Tier II $12,500
Tier III $25,000
Tier IV $28,000

Cost Savings through Right Sizing
Opex Model: Assumption if we chose a Tier II design with a
block/Index utility agreement was negotiated with kWh cost
locked in for 80% of the capacity and the rest 20% at
indexed rates. The cost of kWh at $0.12.
We reached utilization at 2.7MW
Block Power Index Power Draw
Average Density (kW)
Operating Cost Stranded $ 10 year Loss
Annual Cost (3MW) $2,488,320 $622,080 90% 5.4 $2,799,360 $311,040 $3,110,400 Annual Cost (4MW) $3,317,760 $829,440 68% 5.4 $2,799,360 $1,347,840 $13,478,400

Cost Savings through Right Sizing
What’s your actual $/kW?
Block Power Index Power Draw
Average Density (kW)
Operating Cost Stranded $ 10 year Loss Actual $/kW
Annual Cost (3MW) $2,488,320 $622,080 90% 5.4 $2,799,360 $311,040 $3,110,400 $13,889 Annual Cost (4MW) $3,317,760 $829,440 68% 5.4 $2,799,360 $1,347,840 $13,478,400 $18,519
We reached utilization at 2.7MW

Stranded Capacity
• Avoiding misuse of space (Density). POD that
was designed to 10-12kW per rack density that’s
currently operating at 2kW. The stranded capital
expense of this example using Tier II pricing model
noted in the Uptime Table of $12.5k per 1kW, would
put this row at $1.25M over-spent capital.
Solution: Benches were removed from this lab, and
we recovered 60 grid (300kW) locations for an M&A
consolidation without any investment.
• Recovering under utilized space (New footprint &
Criticality). Audits discovered stranded capacity that
helped avoid the build out of 400kW of new capacity
requirement.

• The following table illustrates business requirements (new data center) for future
growth that were satisfied using existing capacities (Location and criticality)_
The greenest and
most efficient data
center is the one
that you did not
build.
• Build out of an additional 2.65MW of capacity for less than 90% cost of building
new space, based on Uptime Institute cost model

Requirement Validation
Inventory Management
Design Decision & Efficiency
• Design to average densities
• Design to actual draw densities and
not nameplate values
• Create relevant KPIs for measurement
and reporting
• Review the KPIs and leverage the
metrics for decision making
• Require business justification behind
technical requirements
• Implement a chargeback model
• Create ROI models that supplement as
a decision making tool for cost saving
potentials over the life of the equipment
• Include efficiency measure from the
beginning and not as an afterthought as
part of the requirement
