Data Centers

Power, cooling, space issues set to escalate

If the data center power, cooling and space problems were causing such headaches in a very depressed IT market, they will become significantly worse in an expanding market

Increasing server sales will escalate data center power, cooling
and space problems, says Gartner.

Rakesh Kumar, research vice president at Gartner, said
“Virtualization and consolidation projects will help offset some of
these issues, but with the snowball effect that these issues tend
to create within an organization, users need to act quickly.”

Mr. Kumar explained that while servers consume only about 15
percent of the direct energy in data centers, there is a cascade
effect. The more servers that exist, the more heat is generated
and, therefore, the more cooling equipment is needed. Hence, if the
data center power, cooling and space problems were causing such
headaches in a very depressed IT market, they will become
significantly worse in an expanding market.

Gartner says users can manage these problems with following
measures:

Do not underestimate the issues.
Quantify
the problem. In all cases, accurate modeling and quantification are
key to addressing the problem in a controlled manner.

Use monitoring tools.
The use of
monitoring tools remains low but is readily available as part of
core server management tools or as separate, server-independent
tools for organizations.

Accelerate consolidation and virtualization
projects.
The benefits of these multiyear projects
particularly accrue toward the end of the project, so users should
accelerate the speed of adoption and change.

Assess the benefits of delaying new server
purchases.
In some cases, it may be beneficial to
delay the acquisition and use capacity that is freed up from
consolidation and virtualization projects. The equation is complex,
because new servers typically use less energy than older ones.
