摘要
Improved techniques for applying performance controls in a data storage system based on overload correlations between units of managed storage objects (UMOs). When a performance indicator (e.g. response time) for a target UMO is outside an acceptable range, a competing UMO that potentially shares at least one potentially shared hardware component with the target UMO is identified. An overload correlation between the target UMO and the competing UMO is generated that indicates an amount of correlation between the performance indicator for the target UMO and a performance indicator for the competing UMO. A performance control is then applied to the throughput of the competing UMO that reduces the throughput of the competing UMO. The amount that the throughput of the competing UMO is reduced is based on the amount of overload correlation between the target UMO and the competing UMO.
