This paper presents MIRAGE, an architecture for data center storage provisioning that takes the approach of maintaining storage services for applications by ensuring well-balanced utilizations in all internal components of the storage infrastructure. We implemented MIRAGE on our local storage infrastructure and observed the sensitivity of the MIRAGE load-balancing algorithm to a combination of performance and heterogeneity skews. We also evaluated MIRAGE by deploying it on a financial data center. We reduced the service times of resource-constrained storage pools by an average of 68%.
