DC Sim overview
What is DC Sim?
DC Sim is a free, web-based rack density calculator designed for data center operators and infrastructure engineers. Without requiring installation or account registration, it determines the maximum number of servers that fit in a single rack by evaluating three independent constraints: physical space (rack units), power (three-phase kW derived from voltage, amperage, and power factor), and cooling (kW). The tool identifies which of the three constraints is the binding bottleneck limiting rack density.
All calculation formulas are openly displayed within the interface, giving engineers full visibility into the methodology. DC Sim runs entirely in a browser, requiring no software installation, no login, and no licensing cost. It is suited for rapid capacity planning assessments, pre-deployment rack design evaluations, and infrastructure audits where quick, transparent constraint analysis is needed.
