ESXi Host in a Cluster AND using local storage?

I have an ESXi host connected to a SAN. It is in a cluster with 2 other hosts using a shared VFMS on the SAN.

This ESXi host also has 3TB of local raid storage.  Is it possible to set up a datastore on these local disks and place VMs there as if they were outside the cluster?

I'm confused if this would even work given that I suppose vCenter would have to show it as part of a cluster AND as a standalone host at the same time...
