With the release of vSphere 5.5 now upon us, before jumping in and performing a fresh install or an upgrade I wanted to highlight the minor changes to the vCenter Server installer, specifically when to use the simple installer and when to use the individual custom install wizards.
With the new release, when you attach your ISO image you will be presented with the updated splash screen
Selecting this option which is now the default will give you an installation of the core components required for vCenter server with the default settings on too a single physical or virtual server. With vSphere 5.5 we have now added the vSphere Web Client into the mix to assist with setting up vCenter Single Sign-On if necessary. Simple Install will install the following core components in the required order specified.
Using the simple install, the components will be installed to the default C:\Program Files\VMware\Infrastructuredestination folder or upgrade the existing version in the installed location. If you have distributed components with vSphere 5.1, this will install all components locally when ran, installing any components anew if not present which may affect you permission and accessibility (ie new vCenter Single SIgn-On instance)
