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.
