Improving NFS Performance on HPC Clusters with Dell Fluid Cache for DAS15The 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 LifeRemaining” and “Failure Predicted”. “Device Life Remaining” is an indication of the amount of datawritten to the device, and is calibrated for the PBW portion of the warranty. It is tracked internally bythe SSD. “Failure Predicted” tracks the health of the internal components of the SSD. If failure ispredicted, it is recommended that the SSD be replaced. This field does not imply performancedegradation but suggests that the SSD is starting to have component failure counts that are higher thanthe preset thresholds.Example output is shown in Figure 4.
