Force provisioning option in vSAN policies is an article that explains in a practical way how the advanced option force provisioning works. Firstly, if you need to know a little bit about vSAN, we have an article that explains what is vSAN (in a basic way) and how to set up a vSAN cluster. Click here to read this article. When the object will place in the vSAN Datastore, a vSAN Storage Policy is used to define how this data will be stored, what level of tolerance, the number of stripes, and other parameters. So, about advanced configuration in a…
vSphere HA Communication Network is an article that explains how vSphere HA Communication Network works in a vSAN Cluster, and what network is used to achieve that. Definitely, the vSphere HA is a classical and useful feature present on the vSphere Stack. vSphere HA provides high availability for virtual machines by pooling the virtual machines and the hosts they reside on into a cluster. Hosts in the cluster will monitor and in the event of a failure, the virtual machines on a failed host will restart on alternate hosts. Note: It is very important here to avoid confusion or mistakes. When…
