Storage Power Management
Storage Power Management is a process of improving the efficiency of electric power consumption of all the concerned storage resources including storage devices, storage controllers and storage network devices. Storage Power Management may sometimes cover related equipment such as power supplies and cooling apparatuses. The definition of “the efficiency” may depend on the situation; system designers and administrators often need to balance electric power reduction against performance degradation.
Electric power consumption of storage devices was discussed mainly with regard to battery-operated computing environments such as laptop PCs. However, due to the rapid growth of power consumption in data centers and the increased interest in environmental issues, much attention has recently been paid to electric power consumption of enterprise-level storage systems. Energy efficiency is recognized as a new direction for research and development of storage...
