Proportional Adaptation for Conservation of Energy (PACE)

The PACE (Proportional Adaptation for Conservation of Energy) project focuses on storage energy management and energy efficient technologies. Our vision is for 'proportional energy' usage for storage, which means:

• When performance matters most, energy usage should be regulated by workload requirements.
• When energy matters most, workload performance should be regulated by energy constraints.

We have been pursuing two threads:

• Proportional energy technique analysis: Quantify effectiveness of various proposed techniques for maximizing storage energy efficiency, primarily in storage environments where average latency constraints are a primary concern.
• Tiering algorithms for storage subsystems: Experiment in a storage systems environment where extents worth of data can be moved between storage tiers, and develop energy-aware algorithms for minimizing energy usage while providing sufficient performance.
