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.
Vsan storage policy settings. Several subsystems within vsan try and limit the impact of changing a storage policy configuration. 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. Vsan verifies that the virtual disk requirements are applied according to the specified virtual machine storage policy settings. Vsan verifies that the correct cluster resources are used at the time of provisioning.
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. Now we will be adding the rules which we require for the vm on the vsan datastore. Vsan storage polices define storage requirements for your virtual machines. Both datastores share the same underlying storage.
First choose the storage type as vsan from the drop down as shown. Read about how we use cookies and how you can control them here if you continue to use this site you consent to our use of cookies. Virtual san fails to provision a virtual machine when the policy requirements are not met but it successfully creates the user defined storage policy.

As of vsan 6 7u3 vmc 1 8 vsan will also batch policy transitions. 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. As we are using the vsan for storage policy leave it as it is and click next. How naming conventions can help with storage policies.
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. Adaptive resync will restrict the effect of any resynchronization traffic on production workloads. For example based on the protection policy vsan determines how many replicas to create.
Storage policy based management spbm can also benefit from naming conventions.
