Dell Unity file systems and NFS datastores support file alert thresholds, which generate warning and error level alerts as space utilization increases. When a file system or NFS datastore passes 75% utilization, a warning level alert is generated. The utilization percent is calculated based on used space, and savings achieved by data reduction and advanced deduplication are not factored in. If the utilization of the resource continues to increase, an error level alert is generated at 95% utilization. This ensures that administrators can easily identify and address any capacity related issues with their file systems or NFS datastores before they run out of space to save data.
With the release of OE version 5.0, custom file alert thresholds are introduced. This feature allows administrators to configure the utilization percentages that a file system or NFS datastore will generate an informational (disabled by default), warning, and/or error level alerts. Thresholds can be configured between 0-99%, and the utilization percent must increase with each subsequent alert severity level. A setting of 0% disables the alert. The default settings are displayed below:
Custom file alert thresholds can be modified by browsing the Properties page of a file system or NFS datastore and selecting the Capacity Alarm Setting link.
