Figure 4. Pcie Ssd Health - Dell PowerEdge EL Manual

Improving NFS Performance on HPC Clusters with Dell Fluid Cache for DAS
The warranty of the device is expressed in number of years and number of Petabytes written (PBW).
For the recommended 350GB SSD drive, the standard warranty is 3 years, 25 PBW.
The health of the device can be monitored using Dell OMSA utilities. OMSA reports the SSD "Device Life
Remaining" and "Failure Predicted". "Device Life Remaining" is an indication of the amount of data
written to the device, and is calibrated for the PBW portion of the warranty. It is tracked internally by
the SSD. "Failure Predicted" tracks the health of the internal components of the SSD. If failure is
predicted, it is recommended that the SSD be replaced. This field does not imply performance
degradation but suggests that the SSD is starting to have component failure counts that are higher than
the preset thresholds.
Example output is shown in Figure 4. For more details refer to [8].
