C. Adding storage only nodes:

Nutanix allows the addition of storage-only nodes to a cluster. This feature is beneficial for environments where data retention for compliance purposes increases, as it provides a cost-effective way to scale storage capacity without adding compute resources.

Storage-only nodes help in efficiently managing and expanding storage capacity while controlling costs, making it a suitable solution for the prospect’s concerns.

Nutanix documentation on cluster configuration and expansion highlights the benefits and use cases for adding storage-only nodes, particularly in scenarios requiring increased storage capacity.

During a 1-click, non-disruptive upgrade on a 3-node Nutanix cluster, if a VM on Node A overwrites an existing block of data while the CVM on Node A is rebooting, Nutanix AOS ensures data integrity by writing two copies of the data across the remaining nodes. This approach maintains data resiliency by ensuring that multiple copies of the data are available even when one of the nodes is temporarily unavailable​​​​.

For a customer intending to build out their VDI environment over 18 months, the systems engineer should highlight the element of Nutanix WebScale architecture that ensures linear performance with predictable scaling.

WebScale Architecture:

Nutanix’s WebScale architecture is designed to provide consistent performance as the environment scales. Each node added to the cluster contributes proportional compute, storage, and network resources.

Linear Scaling:

This architecture ensures that performance remains consistent and predictable as new nodes are added, which is critical for maintaining a consistent user experience in a growing VDI environment.

Benefits:

Predictable Performance: Users can expect the same level of performance as the environment scales.

No Single Point of Failure: The distributed nature of Nutanix’s architecture ensures high availability and resilience, which is crucial for VDI environments.

To configure alerts to notify the administrator before VM CPU utilization hits 90%, follow these steps:

Open the Health dashboard in the Prism web console.

Locate the VM CPU Check alert configuration.

Adjust the alert threshold to a value below 90%, such as 80% or 85%.

Save the changes to ensure that the alert will trigger when VM CPU utilization reaches the newly set threshold.

By lowering the alert threshold, the administrator will receive notifications before CPU utilization becomes critical, allowing for proactive management and mitigation of potential performance issues.
