Should enterprise data center owners consider liquid cooling? The answer is, “Yes.” Should enterprise owners adopt liquid cooling for their data centers? The answer is, “Maybe.” Moving from “consideration” to “adoption” involves sorting through important financial,...

After nearly twenty years of promoting the benefits of data center airflow management, I am afraid I need to confess that sometimes I may leap directly into the minutia of some operational algorithm or perhaps into a debate on the relative merits of some particular...

In previous pieces I have discussed algorithms for accounting for the relationship between pressure drop and data center fan energy and the relationship between airflow management and chiller plant operating efficiency. Our conclusion so far has been that we looked at...
