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 VNX Block arrays, Figure 1 shows the direct connection created by the plug-in to the VNX Block storage processor. The connection to the array's storage processor is made through Navisphere Secure Command Line Interface (NaviSecCLI) to collect array level metrics. One VNX Block storage target is used for each VNX Block array.
Figure 1 VNX Block metric collection architecture
Figure 2 shows how the VNX File storage target collects data from the VNX File storage control station. Using the Secure Shell (SSH) protocol, the plug-in connects to and collects array level metrics from the control station administrating the VNX File that is being monitored. One VNX File storage target is used for each VNX File array.

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 4.
Figure 4 EMC Database Storage page
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 VNX Block Storage page, as shown in Figure 5, displays information about VNX Block arrays. You can view detailed information on the VNX Block array and drill down into secondary pages for information on specific components.
In the Storage Processors pane (1), select a time period of Last Day, Last Week, or Last Month.
The Storage Processors pane (2) shows detailed graphs on the performance of the storage processors associated with this VNX Block. Hover over the graphs to see detailed data points.
In the Storage Pools pane (3), Click a Storage Pool Name link to go to the corresponding Storage Pools page.

The EMC VNX File Storage page, as shown in Figure 6, displays information about VNX File arrays. You can view detailed information on the VNX File array and drill down into secondary pages for information on specific components.
In the Data Movers pane (1), Click a Data Mover Name link to go to the corresponding Data Mover page.
In the File Systems pane (2), Click a File System link to go to the corresponding File System page.
In the Storage Pools pane (3), Click a Storage Pool Name link to go to the corresponding Storage Pool page.
