The modern organizations rely heavily on computer services, often compensated by the data center legacy. Its utilization has grown by leaps and bounds with further addition of cloud computing and virtualization technologies. However, the growth in data centers has doubled the electricity consumption and resulting heat generation.
Nowadays, the power in data centers range from 540 W/m2 to 2160 W/m2, requiring energy amounting to 10MW. Moreover, the adoption of cloud computing has increased the utilization of servers from 10 to 70 per cent, which has exceeded the available capacity for power density and airflow at rack level, leading to power resilience and thermal challenges.
Conventional data centers and the cooling systems are designed considering average power density per square foot, which in reality is not much of an effective method. The amount of heat generated actually varies at rack or row level, depending on the equipment and utilization.
