I'm about ready to integrate the vCenter Server Appliance into our environment, but I have more questions before making the leap.
(I am performing a clean install of vSphere 5.5 - not an upgrade from 4.1 - which is our current environment)
I keep reading that VUM does not work with VCSA. But you can create a Windows VM and install VUM there, then install a plugin(?) to integrate it into VCSA. How does this work exactly? I am doing a clean install of ESXi 5.5 on 3 new Hosts. I will be installing the vCenter Appliance as a VM. I also plan on creating a VM to act as the vSphere Update Manager. Can I utilize that single VM (as the VUM) and use it to upgrade all the ESXi Hosts? Or do I need to build 3 VUMs to update each Host? All this vSphere documentation is making my eyes blurry!
