The first step is to enable SIOC on the datastore. Figure 118 illustrates how the datastore entitled CONCURRENT_DS_1 is enabled for Storage I/O Control. Right-click the datastore in question and select Configure Storage I/O Control. A dialog box appears which by default shows that the feature is disabled. There are two main options available as the current disabled state is default from datastore creation. The first is to enable SIOC with or without statistics, and the second is to disable SIOC but enable statistics with SDRS. In this example, SIOC is enabled by selecting the first option. By default, the option to include I/O statistics for SDRS is enabled. However, as Dell Technologies does not recommend using statistics with SDRS, the box is cleared in the example below. Even if it is enabled, the statistics are irrelevant if statistics are disabled when using SDRS.
The configuration change shows up as a Recent Task and once complete the Configure -> General page lists the feature as enabled as seen in Figure 119.
