Deployment modes

The following key terms apply when using SUM to deploy updates. You can combine the terms to reflect an environment, for example, local-online or remote-online.

Local

The installation runs on the physical hardware you are updating. For example, running on a server to update the system ROM of the server.

Remote

SUM runs on one system, but updates other physical nodes. For example, updating the OA/VC or server firmware across a network.

Online

The installation occurs while the host processor is running in the normal server environment. For example, if the server runs Microsoft Windows Server 2012, the update occurs under this environment. The update does not require you to boot to a special environment to update the firmware. You might need to reboot the node to activate the firmware.

Offline

In Offline mode, SUM boots a small SUSE Linux Enterprise Server 15 boot kernel and enables updates to occur on a single server.

• Only updates the local system.

• Only uses a single baseline to update firmware.

In Offline mode, SUM does not support some features that require the regular local host operating systems.
