The update manager within vSphere has some great enhancements. You can download all the updates with the UMDS tool and place the downloaded updates in a shared repository. A shared repository is a location within your firewall to which patches from various venders may be downloaded using the Update Manager Download Service. When these patches are required for remediation, the system retrieves them from the shared repository, rather than to a remote location, which will save time. The types of locations supported are: local disk, a file URL, or an http URL.
