Intel IT conducted a technology evaluation of Intel® Intelligent Power Node ...Manager
and Intel® Data Center Manager (Intel® DCM). Our goals were to assess the potential
of these Intel® power management technologies to increase data center energy
efficiency, and to validate potential usage models.
We conducted our evaluation in a test environment representing a virtualized data
center, using servers based on Intel® Xeon® processor 5500 series.
We successfully used Intel Intelligent Power Node Manager and Intel DCM to monitor and
cap power consumption across individual servers and groups of servers. For workloads
that were not processor-intensive, we optimized server power consumption by up to
approximately 20 percent without impacting performance, as shown in Figure 1.
Power monitoring is a critical capability that enables us to characterize workloads and
identify opportunities to increase data center energy efficiency. Our evaluation showed
that Intel power management technologies can address key data center power and
cooling challenges, helping to increase computing capacity, reduce power consumption,
and maintain business continuity.

workload, without impacting runtime.
Intel IT, like other organizations, faces significant
data center power and cooling challenges. Rapid
growth in demand drives a continual need for
more computing resources. This is straining the
limits of data center power and cooling capacity.
At the same time, power and cooling costs are
becoming an increasingly important component
of total cost of ownership (TCO).
Ways to accommodate the increasing demand
include building new data centers or adding power
and cooling capacity to existing data centers.
However, both of these options are extremely
expensive and take a long time to complete.
Because of this, we are increasingly applying
alternative approaches that focus on using
existing data center power more efficiently in
order to increase computing capacity, cut power
costs, and reduce Intel’s carbon footprint.
Traditionally, because IT organizations have
lacked detailed information about actual server
power consumption in everyday use, data center
computing capacity has been based on nameplate
power, peak server power consumption, or derated
power. In practice, server power consumption with
real data center workloads is nearly always lower
than this. This situation results in overprovisioned
data center power, overcooling of IT equipment,
and increased TCO.
If we can better understand and control server
power consumption, we can more efficiently use
existing data center power, resulting in benefits
such as increased capacity and reduced power
costs. Applied across tens of thousands of
servers, this could result in considerable savings.
To this end, we conducted an evaluation
