Vsan Storage Policy Rules

When provisioning a virtual machine if you do not explicitly assign a storage policy to the virtual machine the vsan default storage policy is assigned to the virtual machine.

Vsan storage policy rules.

Storage policies for vm in vsan. A storage policy that contains replication rules should not be specified as a default storage policy. Defines the actual data placement or parity method used to tolerate a failure. Vsan requires that the virtual machines deployed on the vsan datastores are assigned at least one storage policy.

Vsan is an software defined solution which uses storage policies to create and configure the storage for the virtual machines. Two storage policy rules will be the focus of this post as we look at differences between non stretched vsan clusters and stretched vsan clusters. In the policy structure section select enable rules for vsan storage and click next. Vsan stretched cluster component examples when using per site policy rules as per site policy rules add local protection objects are distributed into even more components.

In this post we will see on how to create vsan storage policy step by step. In the vsan availability section select none for site disaster. Governs fault tolerance between sites. Governs fault tolerance within each site.

You can change the default storage policy for a selected virtual volumes or vsan datastore. This option helps you to define the number of host and device failures that a virtual machine object can tolerate this value is important for designing the resiliency of your vsan cluster. Because the bandwidth requirements to the witness host are based on the number of components using these policy rules will increase the overall component count. You can configure multiple storage policies based on your requirement and assign them to the virtual machines.

Vmware virtual san storage policies understand rule sets 1 number of failures to tolerate. Enter a meaningful name for the policy and click next. The default policy contains vsan rule sets and a set of basic storage capabilities typically used for. In new vsphere client vsan storage policy rules are renamed.

From the top menu select policies and profiles. Failure tolerance method ftm. Otherwise the policy prevents you from selecting replication groups. Vsan storage policy is an most important feature of vsan.

Vsan storage policy can be created and assigned on per vm or per vmdk level. Vsan is enterprise class storage virtualization software that when combined with vsphere allows you to manage compute and storage with a single platform with vsan you can reduce the cost and complexity of traditional storage and take the easiest path to hyperconverged infrastructure and hybrid cloud evolve to an integrated hyperconverged infrastructure hci solution.
