when reviewing Nutanix cluster upgrades. a customer engineer is concerned that their VM will be forced to repeatedly migrate between nodes. Which Nutanix feature allows VMs to remain on a host during an AOS upgrade?
The concern is that VMs may be forced to repeatedly migrate between nodes during a Nutanix cluster upgrade.
Nutanix Feature:
CVM Autopathing: This feature ensures continuous VM operation by dynamically rerouting I/O and network traffic during node maintenance or upgrades.
Explanation:
CVM Autopathingallows VMs to remain on their current hosts while the Controller VM (CVM) handles the necessary I/O redirection.
This minimizes the need for VM migrations, thereby reducing the operational impact during upgrades.
Outcome:
VMs can remain on their original hosts throughout the AOS upgrade process, ensuring minimal disruption and maintaining performance stability.
References: For more details on CVM Autopathing and its operational benefits, refer to Nutanix documentation on cluster maintenance and upgrade best practices.
