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.
