To accurately size resources for VMs, certain VMs require further data analysis. Specifically, VMs with varying or unpredictable workloads, or those that have shown performance issues in the past, should be analyzed in more detail.
* VM Analysis Criteria:
* prodsrv02: If this VM has variable workload patterns or is known to run resource-intensive applications periodically, it requires detailed analysis to ensure that the resources allocated can handle peak loads without performance degradation.
* prodsrv06: Similarly, if this VM has been identified to have inconsistent performance or varying resource utilization, further analysis is necessary to properly size the resources to meet its demands.
* Data Collection:
* Performance metrics such as CPU, memory, disk I/O, and network usage should be collected over a representative period to understand the peak and average resource requirements.
* Sizing Tools:
* Tools like Nutanix Sizer and Nutanix Collector can be used to gather detailed performance data and provide recommendations based on real usage patterns.

To achieve N+2 resiliency for the entire cluster, the configuration can be adjusted by:
* Increasing the number of Nodes: Adding more nodes enhances the cluster's ability to tolerate failures by distributing data across a larger number of nodes.
* Increasing the SSD capacity per Node: Higher SSD capacity per node can improve data distribution and
* redundancy, ensuring that the cluster can maintain performance and availability even during failures.

Zookeeper in Nutanix is responsible for distributing metadata to ensure availability in case of node or block failure. Metadata includes important information about the state and configuration of the cluster, which is crucial for maintaining cluster operations and consistency.
