Vsan Storage Policy Stretched Cluster
Storage policies have availability attributes and advanced attributes.
Vsan storage policy stretched cluster. Once the configuration is done it is very important to understand and create the vsan storage policy for the stretched cluster to protect the virtual machines across the sites. You can assign storage policies when you create or reconfigure virtual machines. New concepts in vsan stretched clusters. We will discuss vsan stretched cluster storage policy in the upcoming posts.
When working with virtual machine storage policies you must understand how the storage capabilities affect the consumption of storage capacity in the vsan cluster. In vsan 6 6 a number of new enhancements were made to the vsan stretched cluster implementation. Vsan in a stretched storage deployment accomplishes this by synchronously mirroring data across the two sites. The stretched cluster can allow you to have data mirrored to two different sites so that in the event of an entire site failure the vms will simply be.
From a policy perspective we now have the ability to configure both a pftt primary failures to tolerate across sites and an sftt secondary failures to tolerate within sites. We are done with creating the vsan stretched cluster. Vmware vsan 7 stretched cluster with dual site mirroring is configured wrapping up. Vmware vsan stretched cluster guide.
A common question is how stretched clusters differ from fault domains which is a vsan feature that was introduced with vsan version 6 0. For more information about designing and sizing considerations of storage policies see designing and sizing a vsan cluster in administering vmware vsan. One of the beautiful things about vmware vsan is that it opens up the door to many different ways to store your data and protect against failure and disasters. Stretched storage with vsan allows you to split the vsan cluster across two sites so that if a site fails providers are able to seamlessly fail over to the other site without any loss of data.
Availability attributes for vsan vm storage policies site disaster tolerance defines the data redundancy method used by stretched clusters to handle a site failure. Behavior of non stretched cluster policies when transitioning to a stretched cluster once stretched clustering is enabled and configured in a vsan cluster the vms do not impart any secondary local protection logic for data placement.
