Update Manager enables centralized, automated patch and version management for VMware vSphere and offers support for VMware ESX/ESXi hosts, virtual machines, and virtual appliances.
With Update Manager, you can perform the following tasks:
Upgrade and patch ESX/ESXi hosts.
Install and update third-party software on hosts.
Upgrade virtual machine hardware, VMware Tools, and virtual appliances.
Update Manager requires network connectivity with VMware vCenter Server. Each installation of Update Manager must be associated (registered) with a single vCenter Server instance.
The Update Manager module consists of a server component, which you can install either on the same computer as the vCenter Server system or on a different computer, and of client components. There is an Update Manager Client that runs on the vSphere Client, and an Update Manager Web Client that runs on the vSphere Web Client. You can use Update Manager Web Client to view scan results and compliance states for vSphere inventory objects, and use the Update Manager Client to perform patch and version management of the vSphere inventory.
If your vCenter Server system is part of a connected group in vCenter Linked Mode, and you want to use Update Manager for each vCenter Server system, you must install and register Update Manager instances with each vCenter Server system. You can use an Update Manager instance only with the vCenter Server system with which it is registered.
To install Update Manager, you must have Windows administrator credentials for the computer on which you install Update Manager.
You can deploy Update Manager in a secured network without Internet access. In such a case, you can use the VMware vSphere Update Manager Download Service (UMDS) to download update metadata and update binaries.
