Describe VM Data Path Redundancy

The Nutanix cluster automatically selects the optimal path between a hypervisor host and its guest VM data. The Controller VM has multiple redundant paths available, which makes the cluster more resilient to failures. When available, the optimal path is through the local Controller VM to local storage devices. In some situations, the data is not…

Live migration lets you move a user VM from one Acropolis host to another while the VM is powered on. This feature follows similar resource rules as VMHA to determine if migration can occur—as long as enough RAM and CPU cycles are available on the target host, live migration will initiate. Live migration can be…
