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.
Vsan storage policy rules.
Vmware virtual san storage policies understand rule sets 1 number of failures to tolerate.
From the left menu select vm storage policies and then select create a vm storage policy.
Vsan is an software defined solution which uses storage policies to create and configure the storage for the virtual machines.
The default policy contains vsan rule sets and a set of basic storage capabilities typically used for.
Vsan requires that the virtual machines deployed on the vsan datastores are assigned at least one storage policy.
In new vsphere client vsan storage policy rules are renamed.
You can configure multiple storage policies based on your requirement and assign them to the virtual machines.
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.
In this post we will see on how to create vsan storage policy step by step.
Otherwise the policy prevents you from selecting replication groups.
Governs fault tolerance within each site.
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.
Failure tolerance method ftm.
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 storage policy can be created and assigned on per vm or per vmdk level.
From the top menu select policies and profiles.
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 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.
Governs fault tolerance between sites.
You can change the default storage policy for a selected virtual volumes or vsan datastore.
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.
Vsan storage policy is an most important feature of vsan.

Enter a meaningful name for the policy and click next.
Lets discuss about what are the new names applicable in vsphere client these policy components to determine fault tolerance site disaster tolerance.
