Now we will be adding the rules which we require for the vm on the vsan datastore.
Vsan storage policy settings.
These policies guarantee the required level of service for your vms because they determine how storage is allocated to the vm.

As we are using the vsan for storage policy leave it as it is and click next.
You can review the configuration settings for the default virtual machine storage policy when you navigate to the vm storage policies vsan default storage policy manage rule set 1.
In this section we will be configuring the vsan storage policy.

As of vsan 6 7u3 vmc 1 8 vsan will also batch policy transitions.
Several subsystems within vsan try and limit the impact of changing a storage policy configuration.
For best results consider creating and using your own vm storage policies even if the requirements of the policy are same as those defined in the default storage policy.
Vsan verifies that the correct cluster resources are used at the time of provisioning.
Both datastores share the same underlying storage.
Virtual san fails to provision a virtual machine when the policy requirements are not met but it successfully creates the user defined storage policy.
Vsan storage polices define storage requirements for your virtual machines.
For example based on the protection policy vsan determines how many replicas to create.
Deploying a vsan datastore is different from the traditional way of mounting lun from a storage unit or nas nfs devices.
If you configure the object space reservation then reservation will be done on the vsan datastore for the specified object or the vm on which this policy is assigned.
Storage policy based management spbm can also benefit from naming conventions.
How naming conventions can help with storage policies.
In case of vsan for better performance and availability of the vms vsan uses vm storage policy and a storage policy can be attached to individual vms during deployment of the virtual machine.
When used with vsan or vvols the spbm framework takes what used to be all or nothing settings defined on external storage and allows the administrator to assign storage policies to individual vms.
First choose the storage type as vsan from the drop down as shown.
