One or more aspects of the present disclosure relate to relate to analyzing and mitigation storage array latency. In embodiments, an input/output (IO) workload is received by a storage array. Additionally, a latency corresponding to processing one or more IO requests of the IO workload is determined. For example, a factor corresponding to a significant portion of the latency is identified. Further, a remediation action is performed based on the factor identified.

Storage array latency analysis

Storage objects are mapped to host applications in a storage domain. Each of the storage objects is analyzed to determine importance in terms of predetermined criteria such as quality of service of the storage object, replication level of the storage object, size of the storage object, input-output loading of the storage object, and input-output loading of a host application that uses the storage object. Storage objects that satisfy predetermined importance characteristics are automatically tagged with the name of the host application that uses the storage object. The storage objects may also be tagged with the names of data structures that satisfy predetermined importance characteristics. Storage groups, masking views, and volume devices may also be tagged.
