Improving NFS Performance on HPC Clusters with Dell Fluid Cache for DAS
Figure 12 shows that on a cold-cache read for sequential tests, the throughput of the DFC configuration
drops from a peak of ~3,050 MiB/s to ~1,050 Mi/s. Data needs to be pulled from backend storage and
hence the drop in performance. This is lower than the baseline throughput.
