cooling Misconception There is a common misconception that running low density racks instead of higher density ones will be less costly when it comes to power and Running fewer high density racks than lower density ones will yield a lower total cost of ownership cooling but the reverse is actually the case. Running fewer high density racks than lower density ones will yield a lower total cost of ownership because they have far superior compute capabilities while using significantly less data centre resource: switchgear, UPS, power, cooling towers and pumps, chillers, lighting and so on. While next generation servers are capable of operating at higher temperatures than previous solutions, the demand and necessity for intelligent, energy efficient cooling remains in the ascendancy. Among others, this is being driven by increased deployments of high densi
