The EMC Storage Plug-in for OEM 12c consists of several components that work together to collect configuration and performance data from both database servers and EMC storage systems. The plug-in collects metrics from EMC storage systems in different ways based on the optimum connection method.
For collecting VMAX-specific metrics, this plug-in collects storage metrics from apreviously configured Unisphere for VMAX (U4V) installation, as shown in Figure 1. Unisphere for VMAX provides a REST API that the plug-in uses to obtain performance andconfiguration metrics about the VMAX storage systems configured in U4V. The plug-in also uses EMC Solutions Enabler to issue a limited set of SYMCLI commands associated with metric collection from a VMAX array.

The EMC Storage Home target includes a Home page and a Configuration page. The EMC Home page contains a few features, as shown in Figure 2.

In the Storage pane (1), use the menus above the graphs to select a metric to display in the graphs. Select a time period of Last Day, Last Week, or Last Month.
In the Database Storage pane, select a target row to display metrics in the graphs.
Multiple database storage targets can be graphed simultaneously.
In the Graph column (2), select the checkbox to display graph details in the Storage pane. In the Database column (3), click the link to go to the Oracle database target. In the Storage column (4), click the link to go to the EMC database storage target.
In the Array pane, in the Storage Array column (5), click the link to go to the storage target.
The EMC Database Storage pagedisplays information about the Oracle database and the storage used by the database. The page includes a few panes and features such as the hierarchy pane, the storage pane, the database pane, the incidents and problems pane, as shown in Figure 3.

The Hierarchy (1) pane displays the technology stack that is running the database. Click an image or link to go to the corresponding target.
In the Storage pane (2), use the menus above the graphs to select a metric to display in the graphs. Select a time period of Last Day, Last Week, or Last Month.
The Database pane (3) shows corresponding performance information obtained from the standard Oracle database plug-in. This information is used for comparison to the storage metrics in the Storage pane.
The Incidents and Problems (4) pane lists incidents for the Database Storage target, which are also forwarded to the corresponding Oracle Database target.
The EMC VMAX Storage page, as shown in Figure 4, displays information about VMAX arrays. You can view detailed information on individual VMAX arrays and drill down into secondary pages for information on specific components.

From the VMAX Array list box (1), select a VMAX array to display array details in the graphs in the Array pane.
In the Array pane, select a time period of Last Day, Last Week, or Last Month.
In the Front End Directors pane (2), click a Director link to go to the Front End Directors page.
In the Thin Pools pane (3), Click a Thin Pool link to go to the Thin Pools page.
