A Framework for Thermal and Performance Management

Free registration required

Executive Summary

In modern computing facilities, higher and higher operating temperatures are due to the employment of power-hungry devices, hence the need for cost-effective heat dissipation solutions to guarantee proper operating temperatures. Within this context, Dynamic Thermal Management techniques (DTM) can be highly beneficial in proactively control heat dissipation, avoiding overheating. The large-scale adoption of DTM may eventually allow the use of more cost-effective heat dissipation system, with great power consumption advantages for large datacenters. Preventive thermal management is a technique to achieve long-term thermal control via performance degradation. However, this may result in impaired Quality of Service (QoS) and Service Level Agreements (SLAs) breaking.
