when reviewing Nutanix cluster upgrades.

Customer Concern:

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.
