Storage consolidation: Not always a panacea, but can we ease the pain?

The system administrator, faces an arduous task of figuring out whether to consolidate storage workloads, which workloads to isolate, which workloads to co-locate, and how to reduce the interference on co-located workloads? This paper presents an approach to ease this arduous task. We consider different mixes of enterprise storage applications on a high-end SSD to study their performance, system throughput and fairness in their consolidated execution. The paper also considers a static approach using an integrated combination of resource partitioning and data placement to reduce the interference between the workloads.
