For vSphere deployments, VMware provides operating system specific packages (OSPs) as a packaging and distribution mechanism for VMware Tools. These VMware Tools OSPs are packaged using native package formats and standards such as rpm and deb.
Using OSPs provides the following benefits:
Use OSPs if you want to use native update mechanisms, rather than vCenter Server, to manage updates for VMware Tools. If you use an OSP, the VMware Tools status is unmanaged on the virtual machine Summary tab. The status unmanaged means that you cannot use vCenter Server to manage VMware Tools and you cannot use vSphere Update Manager to upgrade VMware Tools.
