View the Current Endurance Level for All SSDs in a Disk Folder
If a disk folder contains SSDs, the summary table displays the percentage of wear life remaining for each SSD and a corresponding
endurance chart.
Steps
1. If the Storage Manager Client is connected to a Data Collector, select a Storage Center from the Storage view.
2. Click the Storage tab.
3. In the Storage tab navigation pane, select the disk folder.
4. On the Disks subtab, locate the Endurance and Endurance Chart columns in the table.
Figure 37. SSD Endurance
The Endurance Chart column shows a wear gauge that indicates the amount of wear life remaining and when an alert will be sent.
The gauge indicators are:
• Red: Fail zone calculated from disk data that estimates when 120 days remain in the life of the disk. An alert is sent when the wear
life moves from the green zone to the red zone.
• Green: Safe operating zone.
• Black Tick Mark: Current Endurance level, in which the far right position indicates 100% endurance (new disk, no wear) and the
far left position indicates 0% (end of life). This is also shown as the Endurance percentage in the Endurance column.
Viewing UPS Status
A UPS provides power redundancy to a Storage Center with the use of a backup battery.
If the power to a Storage Center is cut off, the UPS immediately switches over to the battery giving a Storage Center administrator time
to properly power down the Storage Center or fix the power issue. When the UPS switches to the battery, it sends an on battery
message to the Storage Center. The Storage Center registers the battery message as an alert, turns off write cache, and flushes the
cache to disk. The Storage Center continues to operate in this way until it shuts down or the UPS sends an online message allowing it to
return to normal operations.
