You can configure multiple storage policies based on your requirement and assign them to the virtual machines.
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.
Governs fault tolerance within each site.
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.
The default policy contains vsan rule sets and a set of basic storage capabilities typically used for.
Lets discuss about what are the new names applicable in vsphere client these policy components to determine fault tolerance site disaster tolerance.
In new vsphere client vsan storage policy rules are renamed.
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.
A storage policy that contains replication rules should not be specified as a default storage policy.
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.
Vsan storage policy is an most important feature of vsan.
Otherwise the policy prevents you from selecting replication groups.
Vsan storage policy can be created and assigned on per vm or per vmdk level.
What is vmware vsan.
From the left menu select vm storage policies and then select create a vm storage policy.
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.
Vsan is an software defined solution which uses storage policies to create and configure the storage for the virtual machines.
In this post we will see on how to create vsan storage policy step by step.
Defines the actual data placement or parity method used to tolerate a failure.
Storage policies for vm in vsan.
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.
In the policy structure section select enable rules for vsan storage and click next.
Vmware virtual san storage policies understand rule sets 1 number of failures to tolerate.
Failure tolerance method ftm.
Vsan requires that the virtual machines deployed on the vsan datastores are assigned at least one storage policy.
In the vsan availability section select none for site disaster.
Governs fault tolerance between sites.
