After an abrupt power outage, an administrator receives a number of alerts indicating disks are failed. Prism Element shows a large number of disks offline as seen in the diagram. This single block four node cluster is configured FT1 with an RF2 container holding all user data.
What number of drive failures on different domain (node, block, or rack) could this configuration have tolerated prior to seeing data unavailability?

Study Notes
Prism Central Features
- Image Mapping: Categories in Prism Central allow for mapping images to target clusters.
Disk Failures and Cluster Configuration
- Failure Tolerance: A cluster configured with FT1 and an RF2 container can tolerate up to two drive failures across different domains (node, block, or rack) prior to data unavailability.
Analyzing VM Workloads
- Workload Distribution: To assess the historical distribution of workloads across multiple VMs, the administrator should analyze VM performance metrics and resource utilization data.
Support Case Priority Levels
- Priority Assignment: For issues that occasionally occur without impacting production services, a low-priority support case should be assigned.
Impact of 10 GbE Link Failure
- VM Impact: With a failed 10 GbE link in a four-node AHV-based cluster, user VMs may experience decreased network performance, but overall services remain unaffected due to active-backup configuration.
Diagnostic Tools
- Proactive Support Tool: Nutanix provides a tool that collects diagnostic system data, enabling the delivery of proactive support.
Performance Issues
- CPU Ready Time: High CPU Ready time affects the performance of VMs, indicating that they are waiting for CPU resources.
VM Affinity Policy
- Affinity Policy Relationship: A VM Affinity policy defines relationships where certain VMs must remain together on the same host or must be kept apart to optimize performance and resource allocation.
Continuous Data Availability
- VM-Level Feature: The VM-level feature that ensures continuous data availability is High Availability (HA) functionality.
Image Management in Prism Central
- Imported Images: Images imported into Prism Central are stored in the image library and can be used for deployment across the cluster environment.
