How the SRS is calculated
The SRS is computed as the weighted average of the score of multiple factors such as, System Config Drift, Storage Forecast, Unresolved Events, Missing Emergency Engineering Binaries (EEBs), i.e. patches or hotfixes, Hazardous Configurations, and so on. Then a penalty for each of these factors is subtracted from the total score of 100 points.
The SRS score ranges from 0 to 100 representing the overall reliability and serviceability of the system. A higher SRS indicates better Veritas appliance availability, reduced unplanned downtime, rapid fault detection and resolution, and overall lower costs of remediation.
Penalties are subtracted for the following factors that affect the total SRS of 100 points:
Penalty | Description |
|---|---|
Unresolved events penalty | Number of unresolved events observed for the system. |
Storage forecast penalty | One or more storage volumes are forecasted to be at the risk of reaching their maximum storage capacity. |
Config drift penalty | Drift or deviation observed between the actual hardware/software configurations of the system from its ideal recommended configuration for a model. |
Missing patch/hotfix penalty | Absence of one or more patches or hotfixes that were recommended for the system. |
Hazardous configuration penalty | Presence of hazardous configurations observed on the system. This penalty is a compound risk analysis for certain configuration drift detections that identify potential known contributors to data loss, data unavailability, or premature component failure. |
Memory configuration analysis penalty | Inadequate and/or invalid memory footprint observed on the system. |
Missing plugin penalty | One or more AutoSupport plugins are not reporting data. |
Call Home penalty | System observed to be not calling home in the last specific number of hours. |
Support contract penalty | Inadequate support level, or the support contract is at the risk of expiry. It also considers if the hardware is approaching End of Support Life (EOSL). |
The SRS scores are rated as:
Poor - from 0 to 69
Okay - from 70 to 84
Good - from 85 to 94
Excellent - from 95 to 100
The insights offered by the SRS and recommendations allow the system administrators to ideally avoid, or proactively support a wide range of potential issues before they occur.
