When installing vCenter 6, you will be guided through the install wizard. One of the requirements is a 64-bit Data Source Name (DSN) if you are connecting to a remote SQL database.
Follow these steps to get your DSN setup quickly and be on your merry way:
1. Open ‘Control Panel’
2. Select ‘Administrative Tools’
3. Double-click ‘ODBC Data Sources (64-bit)’
5. DO NOT SELECT SQL SERVER FROM THE LIST! if this is the only option that shows up you will have to download and install the SQL Server Native Client from Microsoft HERE:
7. Choose a name for the data source. I keep mine as descriptive as possible. ‘vCenter’ is pretty easy to remember what the data source will be for. Add a description (optional), and input the ‘Server’ the database is located on.
You now have a 64-bit DSN that can be used to install vCenter Server 6 with a remote database.
