Claim One:
1. A method for detecting a bottleneck in a multi-tier enterprise storage system (ESS), comprising: identifying a set of components distributed among a set of tiers in the multi-tier ESS; determining a total capacity of each of the set of components based on a corresponding set of component models; determining a current load on each of the set of components; determining, based on the total capacity and the current load, a utilization measurement for each of the set of components, the determining comprising an analysis of a utilization at a physical disk level, and an analysis of a utilization at at least one of a network shared disk level and a logical unit number level; identifying at least one component, from the set of components, causing the bottleneck based on the utilization measurement; determining whether the bottleneck is temporary by comparing a predicted load of the at least one component to the total capacity of the at least one component; and providing remediation for the identified at least one component if the bottleneck is determined not to be temporary.
