The layout decisions made by OneFS can be optimized to better suit the workflow.  There are three types:  Random, Concurrency, and Streaming.  The default pool I/O optimization for the data access pattern is “Concurrency”.  Below are the use cases for each:  Concurrency Best for many clients accessing the same data Prefers to use one disk per node for all stripe units of a file  Streaming Best for single stream workflows Prefers to use as many disks as possible per file  Random Same layout as Concurrency, but with prefecting turned off Optimized for random access similar to iSCSI
How do I optimize the performance of my data layout within a pool?
