INDUSTRY 4.0
conditions within the data center. This is a fundamental precept if the viability of preestablished use cases
is to be realized. Ultimately the cost of the calibration
efforts must be considered as part of the ROI of the
digital twin.
Digital Twin Ongoing Commissioning
Digital twins are functional beyond the "what if" modeling scenarios, particularly when considering real-time
calibration methods. Digital twins can serve as ongoing
commissioning tools to fine-tune and update a data center's control system and HVAC over the life of operations
as well.
Changes in IT loads often necessitate changes in the
HVAC and control system settings and sequences of
operations. The necessity of these updates is frequently
ignored until some failure mode occurs or an audit is
conducted.
Today's commissioning processes are largely manual
and are typically initiated when major changes to
infrastructure occur, such as power or cooling system
changes. However, rarely is the commissioning process
initiated by major changes to IT infrastructure alone.
Examples where IT activities should initiate the commissioning process may include:
* IT hardware additions or removals;
* IT hardware relocations;
* IT hardware density changes;
* IT software modifications (higher CPU utilizations,
etc.); and
* IT software modifications (change of software on
the servers, etc.).
The above changes can have profound implications on
the loads profile or density distribution within a data
center and could go completely unnoticed without a
tool that continuously monitors these trends. Typical
control systems are reactionary to modifications in the
system operations, not predictive. Even with artificial
intelligence of control systems data sets, the results
are historical trend analysis of what has occurred, not

In high-performance data center environments,
maintaining proper airflow isn't just important -
it's critical. AMCA Class 1A Leakage rated CD50,
CD60 and TED50 control dampers from Ruskin®
excel in these applications. In conditions where
outside temperatures are lower than inside,
the TED50 thermal efficient model features
insulated blades with a break between twin
seals to eliminate thermal transfer and reduce
condensation. Count on the proven strength of
Ruskin control dampers to deliver reliable airflow
control under pressure.
