eWave: Leveraging Energy-Awareness for In-line Deduplication Clusters

摘要: In-line deduplication clusters provide high throughput and scalable storage/archival services to enterprises organizations. Unfortunately, comes at the cost of activating several storage nodes on each request, due parallel nature superchunk routing. This may prevent from exploiting disk standby times preserve energy, even for low load periods. We aim enable exploit valleys save up energy. To this end, we explore feasibility deferred writes, diverted access workload consolidation in setting.We materialize our insights eWave: a novel energy-efficient middleware clusters. The main goal eWave is energy-aware operation without modifying layer. Via extensive simulations experiments an 8--machine cluster, show that reduces energy 16% 60% common scenarios with moderate impact performance during
