Comprehensive bottleneck detection in a multi-tier enterprise storage system
First Claim
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.

Abstract
Embodiments of the present invention provide approaches (e.g., online methods) to analyze end-to-end performance issues in a multi-tier enterprise storage system (ESS), such as a storage cloud, where data may be distributed across multiple storage components. Specifically, performance and configuration data from different storage components (e.g., nodes) is collected and analyzed to identify nodes that are becoming (or may become) performance bottlenecks. In a typical embodiment, a set of components distributed among a set of tiers of an ESS is identified. For each component, a total capacity and a current load are determined. Based on these values, a utilization of each component is determined. Comparison of the utilization with a predetermined threshold and/or analysis of historical data allows one or more components causing a bottleneck to be identified.
