The components of the Performance/Node Failover Planning page are displayed in a grid and in the Comparing pane. These sections enable you to assess the impact of a node failover on the performance of the takeover node.
The Performance/Node Failover Planning page displays a grid containing statistics for latency, IOPS, utilization, and performance capacity used.
In the grid, each node is assigned one of the following roles:
The node that takes over for the HA partner when the partner fails. The root object is always the Primary node.
The node that fails in the failover scenario.
The same as the Primary node. Performance statistics displayed for this node show the takeover node's performance after it takes over the failed partner.
You can click the name of the Partner node if you want it to become the root object. After the Performance/Node Performance Explorer page is displayed, you can click the Failover Planning tab to see how performance changes in this node failure scenario. For example, if Node1 is the Primary node and Node2 is the Partner node, you can click Node2 to make it the Primary node. In this way, you can see how the estimated performance changes depending on which node fails.
The following list describes the components displayed in the Comparing pane by default:
By default, statistics for both the root object and the partner node are displayed in the Comparing pane. Unlike in the Performance/Node Performance Explorer page, this page does not display the Add button for you to add objects for statistics comparison.
You can customize the Comparing pane in the same way as you do in the Performance/Node Performance Explorer page. The following list shows examples of customizing the charts:
