Abstract

The present idea generally relates to the field of Energy Management especially in the area of cost management of a dynamic IT environment. The idea proposes an energy driven approach to optimize the costs of electrical power and implementation logic to negotiate volatile power rates as provided by power plants. This approach defines a method and system for energy driven integration into a data center and facilities management.

Dynamic Power Cost Management

1 Technical Field of the Idea

The present idea generally relates to the field of Energy
Management especially in the area of cost management of a
dynamic IT environment. The idea proposes an energy driven
approach to optimize the costs of electrical power and
implementation logic to negotiate volatile power rates as
provided by power plants. This approach defines a method and
system for energy driven integration into a data center and
facilities management.

2 Current Situation

Most expense management systems as part of data center
management systems focus on power reduction. In addition power
expense management focus on single facility location and power
management on machine level. Data center cooling systems
normally are less managed and not/loosely coupled to cooling
demands of computer systems. The current application
management / service management / cost management does not
take care of variable expense curves for electrical power
provided by external power plants. There is a target conflict
in the market between power supplier and power consumer:

A power supplier tries to optimize on volume of
energy delivery combined with less expense costs for
newly upcoming carbon emission certificates.

A consumer tries to optimize on less energy
consumption.

2.1 Related work:

Metering and accounting of resource usage is performed by
dedicated products such as TUAM (IBM Tivoli Usage and
Accounting Manager) etc.

These metering products measure in the context of a
resource utilization and do not optimize the cost
with respect to the power consumption of whole data
center.

Power measurement of resources is performed by products
such as IBM Active Energy Manager HP Modular Cooling
System Management Software and HP Insight Manager. These
products use local resource information and collect data
which is stored in a database. It is a collection of data
with reporting in different way. These products measure
only in the context of a resource and are not aware of
the context of the data center environment.

There is no known solution for the required combination.

3 Motivation

Currently the demand for energy is growing which leads to
rising energy costs. Cooling systems are not managed with
respect to their energy consumption and are often not linked
to the machine load. Cooling is not turned down even if
several computers are switched off (e.g. Blade Center). There
is a missing integration between data center computing targets
(e.g. SLA) and energy expense planning of a DC. No correlation
takes place between important aspects like percentage of SLA
fulfilment and penalties for SLA violation. There is no aspect
considering flexible power rate changes. There is no global
view for power cost saving opportunities.

The total cost of IT equipment or IT service is the net total
cost of all components that can be measured. Such costs
