Exploring Trade-Offs between Energy Savings and Reliability in Storage Systems

Employing a large number of storage devices, as is the current trend in realizing large-capacity storage systems, not only leads to an increase in the number of failures in the system [1, 2, 4, 15] but also results in significant energy consumption [15-18] (accounting for as much as 27% of a data center’s total energy consumption [17]).
