You can probably create a separate datastore cluster and move your DMZ vms to it.
1. Create a datastore cluster
2. Migrate your DMZ vms to the datastore that you plan.
3. Add this datastore to the datastore cluster.
Thanks for reply
As I mentioned I can't dedicate a separate datastore for DMZ Machines.All VMs are in the same data store.any idea?
thank you for your quick reply
I'm looking for a way like zoning.by zoning you don't be able to see other LUNS.
If I change VM Storage Policy I will able to see other LUNS.
