To tolerate up to 2 simultaneous disk failures across different nodes, the minimum number of nodes required is
5. This configuration ensures that there are enough nodes to maintain data redundancy and availability in the event of multiple disk failures, leveraging Nutanix's Resiliency Factor (RF) mechanisms .

To ensure the solution does not exceed 80% CPU utilization when a node is placed in maintenance mode, the SE should:
* Access Sizer: Open the Nutanix Sizer tool.
* Create New Scenario: Start a new scenario for the project.
* Define Workload: Enter the details of the current workload, specifying resource requirements.
* Customize CPU Threshold:
* In the sizing options, customize the CPU threshold to 80%. This setting ensures that the calculated resources account for keeping CPU utilization at or below 80% when a node is taken out of the pool for maintenance (N+0).
* Review Configuration: Verify that the proposed configuration meets the 80% CPU utilization requirement under maintenance conditions.
This approach ensures that the solution is appropriately sized to handle the specified workload without exceeding the desired CPU utilization threshold.

To address concerns about restoring data locality for VMs after they migrate during an AHV upgrade, it should be highlighted that AHV's built-in scheduler automatically restores data locality. This means that after the VM migration, the scheduler ensures that the VM data is moved to the local storage of the destination node, thereby maintaining optimal performance and data locality.

* Understanding Critical Requirements:
* For critical business operations, high availability, performance, and redundancy are essential to ensure minimal downtime and robust performance.
