Shared Storage for using VMotion during testing in VMware Workstation

When using VMware Workstation to test VMware Virtual Infrastructure you need Shared Storage for your virtual ESX servers in order to test features like VMotion. Until now I used an additional VM like this or this to connect its storage via iSCSI. But doing so you have another VM consuming the limited resources of your physical host. But there is another solution. Just use shared storage as described in this blog post. So you can test features like VMotion, HA and DRS without running an additional VM just for shared storage.
