Vsan Storage Policy Rules

Governs fault tolerance between sites.

Vsan storage policy rules.

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. Lets discuss about what are the new names applicable in vsphere client these policy components to determine fault tolerance site disaster tolerance. Vsan is an software defined solution which uses storage policies to create and configure the storage for the virtual machines. Failure tolerance method ftm.

Otherwise the policy prevents you from selecting replication groups. 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. 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. From the top menu select policies and profiles.

A storage policy that contains replication rules should not be specified as a default storage policy. From the left menu select vm storage policies and then select create a vm storage policy. Storage policies for vm in vsan. In this post we will see on how to create vsan storage policy step by step.

Vsan storage policy is an most important feature of vsan. You can change the default storage policy for a selected virtual volumes or vsan datastore. What is vmware vsan. In new vsphere client vsan storage policy rules are renamed.

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. Vmware virtual san storage policies understand rule sets 1 number of failures to tolerate. Enter a meaningful name for the policy and click next. Vsan requires that the virtual machines deployed on the vsan datastores are assigned at least one storage policy.

In the policy structure section select enable rules for vsan storage and click next. Governs fault tolerance within each site. You can configure multiple storage policies based on your requirement and assign them to the virtual machines. In the vsan availability section select none for site disaster.

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. Vsan storage policy can be created and assigned on per vm or per vmdk level.
