Update Manager stores patch and extension metadata, as well as downloaded virtual appliance upgrades in the Update Manager repository.
You can use the patch repository to manage patches and extensions, check on new patches and extensions, view patch and extension details, view which baseline a patch or an extension is included in, view recalled patches, import patches, and so on.
You can use the virtual appliance repository to view change log information about the virtual appliance upgrades and accept EULAs for the available upgrades.
If your vCenter Server system is connected to other vCenter Server systems by a common vCenter Single Sign-On domain, and you have at least one Update Manager instance, you can select the Update Manager repository that you want to view.
The patch repository and the virtual appliance upgrades are displayed in the Update Manager Administration view.
