Configuring IOA Using Cisco DCNM-SAN

This chapter describes how to configure I/O Accelerator (IOA) using Cisco DCNM-SAN.

This chapter contains the following sections:

IOA Manager

The IOA Manager is a graphical user interface (GUI) for configuring and managing IOA. The IOA Manager user interface consists of a navigation pane on the left that displays a hierarchy and an information pane on the right that displays the contents of the item that you click in the navigation pane. The hierarchy is a tree structure that contains elements that you can configure with IOA Manager. It also consists of a toolbar for quick access to the most commonly used options and a Fabric drop-down list box. The Fabric drop-down list box allows you to directly access the fabrics managed by Cisco DCNM-SAN. The Fabric drop-down list box will be available only if more than one fabric is open.


Note

  • Cisco DCNM-SAN Client standalone supports IOA Manager from Release 5.0(1a).

  • When you perform some of the time-consuming configuration activities using IOA Manager, the progress bar indicates that the configuration actions are in progress. You need to wait until the action is complete. You can click Stop to cancel the action. However, stopping the action may not roll back the transactions that were executed.

Figure 1 shows the IOA Manager interface.
