Questioning default configurations and performance settings in data centers, recognizing that many energy-consuming features were never intentionally chosen.
The uncarved block, or pu, is a central Taoist metaphor representing potential before modification, nature before culture shapes it. In data centers, the uncarved block is lost when systems are configured with inherited defaults—maximum performance settings, redundancy features never questioned, security protocols applied without assessment, cooling thresholds set by manufacturers rather than actual needs. Each setting was carved by someone, sometime, for reasons that may no longer apply. Yet teams inherit these configurations and rarely revisit them. A server set to maximum CPU frequency for unknown reasons continues burning energy. A cooling system maintaining constant 68°F operates identically in winter and summer. Redundant systems protect against failures that never occur. Laozi teaches that the uncarved block contains all possibility without waste. Data centers should periodically recover pu by questioning inherited settings: Do we actually need this performance level? Does this redundancy serve current risks? Can we return to simpler configuration? Removing unnecessary features and returning to essential defaults often yields dramatic energy reductions.
