In most cases (in small environment) a default installation of vCenter Server and its components could work. Considering that the default disk of Windows Server 2008 R2 and 2012 is 40 GB (at least in a VMware virtual environment) it can store all the installation without any directory changes.

Except for the Upload Manager (VUM) that need a reasonable space for store the patches (usually not more than 20GB, but in some case also more, and the installer suggest at least a 120 GB disk).

If you forget to change the patches directory during the installation (by default it’s C: in a position that could change from Windows Server 2003 to Windows Server 2008 and latest version), this VMware KB can help you to fix the issue: Changing the download location for VMware vCenter Update Manager patch repository (1004152).
To change the default download location for patches you have to stop Update Manager service and then manually change an XML file:

  • vci-integrity.xml file, the default file location is C:Program FilesVMwareInfrastructureUpdate Managervci-integrity.xml. Note: in 64-bit Windows, the default file location is C:Program Files (x86)VMwareInfrastructureUpdate Managervci-integrity.xml.
  • Search for patchStore. You see an entry similar to: C:Documents and SettingsAll UsersApplication DataVMwareVMware Update ManagerData (location is different in Windows Server 2008)
  • Copy the old directory’s data or run the vCenter Update Manager download update
  • Restart the VMware vSphere Update Manager Service. Right-click My Computer > Manage > Services and Applications > Services > VMware Update Manager Server > Restart
