Improving NFS Performance on HPC Clusters with Dell Fluid Cache for DAS
25
4. Conclusion
This Dell technical white paper describes a method to improve NFS performance using Dell Fluid
Cache for DAS in an HPC environment. It presents measured cluster-level results of several different
I/O patterns to quantify the performance of a tuned NFS solution and measure the performance boost
provided by DFC.
The test results in this paper indicate that DFC is a great fit for environments where:
• There is heavy read I/O workload, either sequential or random reads.
• Heavy random write I/O workload with a large number of clients writing to the storage.
• Lots of clients are performing I/O at the same time.
• Mixed I/O workload where it is critical to sustain a balance between throughput and IOPs and
an SSD based solution is the best fit.
