To curtail data centers’ huge cooling power consumption and water demand (for cooling), air-side economizer has been increasingly adopted to cool down servers. Recently, another sustainability practice, rainwater harvesting, has also seen a growing adoption in data centers, potentially leading to water self-sufficiency without connecting to water utilities to supply cooling water. Nonetheless, ...

Furthermore, the companies reported high inventory levels as a problem. Hence, the companies often had a high number of cores, spare parts or hal...
