An out-of-band uses an Ethernet network, which sends requests and event information between the storage subsystem and the . The Ethernet isolates the data from the requests and event information. Data is sent through the directly to the by using the input/output (I/O) connections.
To manage an out-of-band storage subsystem, attach cables from the network to the Ethernet connection of each controller in the storage subsystem. Next, define the IP address for each controller or name. To add the storage subsystem to the window, select either Edit >> Add Storage Subsystem or Tools >> Automatic Discovery .
The out-of-band management method is in contrast to the in-band method. The in-band method lets you manage the storage subsystem from your storage management station through the network connection on the host and then through its I/O connection to the storage subsystem. The host must be running the host-agent management software.
You can manage a storage subsystem by using one or both types of network management connections (in-band or out-of-band). The Enterprise Management Window shows the appropriate management connections in its Tree view and Table view.
