Create a shared disk

I remember that many years ago, while using VMware Workstation 5 or something like, there was a way to create a disk to be shared between 2 VMs in order to play a simple cluster.

I remember that I had to edit something in the configuration files (maybe .vmx files) but I lose the ponter to the page describing the solution.

Is it still possible with WMware Player 14?

I know it is a solution only for testing purposes, but years ago it worket fine...
