Lower density brings server efficiency and cooling gains
An exclusive focus on densification and DLC (as if they were inevitable) risks becoming tunnel vision that ignores costs and alternative choices. For IT infrastructure not fully transitioning to DLC, keeping densities moderate may make more sense.
Dry cooling energy performance can rival evaporative cooling
Cooling systems with similar energy performance can vary significantly in water consumption. An analysis of facility data confirms that evaporative cooling's efficiency advantage may be limited and dependent on unacceptable levels of water use.
