Comprehensive bottleneck detection in a multi-tier enterprise storage system

A system for detecting a bottleneck in a multi-tier enterprise storage system (ESS), comprising:

• a bus;
• a processor coupled to the bus;
• and
• a memory medium coupled to the bus, the memory medium comprising instructions to:
• identify a set of components distributed among a set of tiers in the multi-tier ESS;
• determine a total capacity of each of the set of components based on a corresponding set of component models;
• determine a current load on each of the set of components;
• determine, 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;
• identify at least one component, from the set of components, causing the bottleneck based on the utilization measurement;
• determine 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
• provide remediation for the identified at least one component if the bottleneck is determined not to be temporary.

A computer program product for detecting a bottleneck in a multi-tier enterprise storage system (ESS), the computer program product comprising a computer readable storage media, and program instructions stored on the computer readable storage media, to:

• identify a set of components distributed among a set of tiers in the multi-tier ESS;
• determine a total capacity of each of the set of components based on a corresponding set of component models;
• determine a current load on each of the set of components;
• determine, 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;
• identify at least one component, from the set of components, causing the bottleneck based on the utilization measurement;
• determine 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;
