Common Mistakes to Avoid
Common selection mistakes come from choosing a tool with the wrong modeling depth, wrong workflow ergonomics, or missing visualization and scenario scaffolding.
Selecting a network or topology tool for scheduling policy evaluation without datacenter-native constructs
GNS3 focuses on topology-driven emulation and protocol debugging using QEMU and container nodes, so VM scheduling and task brokers require extra modeling effort. SimPy can model queueing precisely but it lacks built-in cloud or networking stack abstractions, so datacenter-level policy comparisons need significant custom design.
Assuming built-in visualization matches IT network views
OMNeT++ provides extensible tracing and visualization hooks, but clear data center views often need customization for debugging clarity. Arena Simulation offers process modeling views, but topology views are less purpose-built for IT network simulators, so network-centric stakeholders may need additional interpretation.
Underestimating setup and modeling overhead for complex scenarios
GNS3 can require labor-intensive setup and troubleshooting as device templates may need manual tuning for accurate behavior. OMNeT++ model creation has a steep setup curve because it depends on learning OMNeT++ concepts and build tooling for custom components.
Choosing an equation-based tool without ensuring reusable data-center component libraries exist
OpenModelica is strong for Modelica-based energy and control system modeling, but data center specific libraries for IT, HVAC, and controls are limited. Teams then face engineering work to create missing building blocks and to orchestrate scenario visualization compared with specialized tools.
