The Data Center Energy Landscape IT needs to bridge growth with sustainability

The Situation:

• Information technology (IT) has the power to be an equalizer across societies

•The cost of IT services, and by extension the cost of energy, is prohibitive to widespread adoption

•Energy costs account for approximately 70 percent of data center operational costs1

•Private and public clouds are projected to double by 2020 2



3

Sustainability: A Holistic Perspective Integrated supply-demand management of available energy

Approach:

Balance energy supply with demand, scheduling IT workloads based on resources availability and service level agreements (SLAs). Supply side:

• Energy and cooling resources

from local, renewables

Demand side:

• IT workloads

HP Net-Zero Energy Data Center Architecture Benefits

Results: The HP Net-Zero Energy Data Center architecture significantly reduces overall energy demand in the data center. • Cuts total power usage by 30 percent • Reduces dependence on the grid power & costs by more than 80 percent • Lowers capital investments and operational costs, while ensuring business as usual

Making IT Services Available to the Masses

Service Delivery

Metric:

Goal:

Enable construction and operation of a data center that consumes net-zero energy from the

grid over its lifetime, with a 2-year payback, while meeting service-level agreements.

Approach:

Develop supply and demand management technologies to minimize overall service delivery costs.

Net-Zero Energy Importance of Planning

• Case Study Scenarios • Net-zero-1: (Integrated Supply-Demand Management)

• Objectives

• Achieve net-zero operation over a 24 hour time period • Energy demand of IT and cooling is equal to the renewable supply

• Minimize energy exchange (with grid or energy storage)

• Prioritize critical workload over non-critical workloads

• Net-zero-2: (No Integration) • Objectives

• Achieve net-zero operation over a 24 hour time period • Energy demand of IT and cooling is equal to the renewable supply
