Improving NFS Performance on HPC Clusters with Dell Fluid Cache for DAS 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. 5.
