You can set up UMDS to download upgrades for virtual appliances, or patches and notifications for ESX/ESXi hosts. You can also set up UMDS to download ESX/ESXi 4.x and ESXi 5.x patch binaries, patch metadata, and notifications from third-party portals.

After you download the upgrades, patch binaries, patch metadata, and notifications, you can export the data to a Web server or a portable media drive and set up Update Manager to use a folder on the Web server or the media drive (mounted as a local disk) as a shared repository.

You can also set up UMDS to download ESX/ESXi 4.x and ESXi 5.x patches and notifications from third-party portals.

To use UMDS, the machine on which you install it must have Internet access. After you download the data you want, you can copy it to a local Web server or a portable storage device, such as a CD or USB flash drive.

The best practice is to create a script to download the patches manually and set it up as a Windows Scheduled Task that downloads the upgrades and patches automatically.
