Managing server energy and operational costs in hosting centers
The growing cost of tuning and managing computer systems is leading to out-sourcing of commercial services to hosting centers. These centers provision thousands of dense servers within a relativelyExpand

Evaluating STT-RAM as an energy-efficient main memory alternative
In this paper, we explore the possibility of using STT-RAM technology to completely replace DRAM in main memory. Our goal is to make STT-RAM performance comparable to DRAM while providing substantialExpand

Optimal power cost management using stored energy in data centers
Since the electricity bill of a data center constitutes a significant portion of its overall operational costs, reducing this has become important. We investigate cost reduction opportunities thatExpand

Benefits and limitations of tapping into stored energy for datacenters
Datacenter power consumption has a significant impact on both its recurring electricity bill (Op-ex) and one-time construction costs (Cap-ex). Existing work optimizing these costs has reliedExpand
