Storage array health score

For each storage array in a storage system, a single value score indicative of the overall health of the respective storage array is calculated. Storage array health score may be tracked over time and used to identify storage arrays in need of maintenance. The storage array health score may be calculated as a composite of four component scores: physical component health, logical component health, Service Level Objective compliance and Best Practice Configuration Compliance. The physical component and logical component scores may be based on multiple different category health scores, and each category health score may be based on multiple instance health scores. Health scores may be used to identify remedial actions and predict health score increase as a result of remedial actions.
