New White Paper: Best Practices for Optimizing Big Data Performance on vSphere 6

A new white paper is available showing how to best deploy and configure vSphere for Big Data applications such as Hadoop and Spark. Hardware, software, and vSphere configuration parameters are documented, as well as tuning parameters for the operating system, Hadoop, and Spark.

The best practices were tested on a Dell 12-server cluster, with Hadoop installed on vSphere as well as on bare metal. Workloads for both Hadoop (TeraSort and TestDFSIO) and Spark (Support Vector Machines and Logistic Regression) were run on the cluster. The virtualized cluster outperformed the bare metal cluster by 5-10% for all MapReduce and Spark workloads with the exception of one Spark workload, which ran at parity. All workloads showed excellent scaling from 5 to 10 worker servers and from smaller to larger dataset sizes.
