Data center spaces can consume many times as much electricity as standard office spaces. With such large power consumption, they are prime targets for energy-efficient design measures
Learn MoreOverall, the energy saving potential in data centres and server rooms is high and may exceed 50% in many cases, depending on the specific IT and infrastructure. In the past the focus of energy saving measures has been on eficient solutions for power supply and cooling. More recently also measures addressing IT hardware eficiency are considered.
This gives a chance to reduce the energy consumption of storage systems and also provides a research space for cache management technique. According to the works of Ref., the offline and online PA-LRU (Partition-based LRU) algorithm (Power-aware Cache Replacement) was proposed to achieve the energy saving of storage systems.
Rack servers tend to be the main perpetrators of wasting energy and represent the largest portion of the IT energy load in a typical data center. Servers take up most of the space and drive the entire operation. The average server utilization (average to maximum activity) is generally in the range of 20% to 40% in enterprise settings.

The Dead Sub-Block Predictor (DSBP) 5. CASHIER, a Cache Energy Saving Technique 6. A multiple linked caches (MLC) approach 4. Energy conservation of computer rooms
Experimental results show that this algorithm can achieve energy saving by 15%-20% of the refrigeration equipment and reduce the overall cost by 5%-20% of the data center.
According to references, thermal management and power/energy management of a data center depend heavily on server power consumption models, although several models have been proposed and used to evaluate the potential of energy management to reduce energy use, a more thorough investigation of these models and their applications is required.
