The data center's power, cooling and standby power supply must be able to adequately support current and future needs. Whether IT is building, refreshing, or moving the data center, it is important to understand these requirements. Accurate estimates of facility requirements are a critical input to the project’s final budget. Once the load estimate has been determined, IT should seek professional expertise as data center construction requires specialized skills.
This tool can be used to determine a high level estimation for the data center's power, cooling, and standby power requirements within a range of 10%-15% accuracy.
