In various examples, a cooling-performance assessment may be determined for each unit of IT equipment. For example, in the context of a data center, a cooling-performance assessment may be determined for each rack in the data center. The cooling-performance assessment may classify each rack as having “good” cooling, “marginal” cooling, or “bad” cooling. The classification may be determined based on IT-inlet temperatures (that is, input-air temperatures) and capture indices (for example, CACIs and/or HACIs). In various examples, the IT-inlet temperatures and capture indices for each unit of IT equipment may also be classified as “good,” “marginal,” or “bad,” and the cooling-performance assessment may be determined based on these classifications. In other examples, the cooling-performance assessment may be determined based on the IT-inlet temperatures and/or the capture indices directly, rather than being based on classifications thereof. Although in some examples a cooling-performance assessment may be determined for each rack, in other examples a cooling-performance assessment may be determined for units of IT equipment at a lower level of granularity, such as for each rack server, or at a higher level of granularity, such as for each row of racks.
