VMware vSAN: Introduction — Lesson 4: Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning

Learning Objectives

• Break down the prerequisites, components, roles, and decision points involved in Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning.
• Complete a controlled activity for Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning and capture vSAN monitoring checklist and learner action plan.
• Challenge the result with a health warning being dismissed without checking whether data redundancy is reduced, then justify the corrective action.

Detailed Topics

• Health service
• Performance basics
• Capacity views
• Alerts
• Disk faults
• Network issues
• Support bundles
• Backup concepts
• Upgrades
• And next-step learning
• Decision ownership, prerequisites, and acceptance evidence for Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

Using realistic infrastructure, identities, and workloads, the instructor demonstrates Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning. Checkpoints are captured in vSAN monitoring checklist and learner action plan, with discussion of alternatives, side effects, and acceptance conditions.

Hands-On Exercise

Configure and test Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning with representative infrastructure or application data. Use “a health warning being dismissed without checking whether data redundancy is reduced” as the troubleshooting challenge, compare hypotheses, retest the affected path, and complete vSAN monitoring checklist and learner action plan for review.

1. Record the starting state, assumptions, identities, topology, and expected outcome.
2. Execute the planned workflow and collect evidence at each material checkpoint.
3. Test one valid path, one boundary condition, and the stated failure scenario.
4. Document the correction, retest result, rollback option, and follow-up owner.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how vSAN monitoring checklist and learner action plan should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Diagnose Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning by checking effective state, ownership, dependencies, health, logs, and recent changes. Use vSAN monitoring checklist and learner action plan to locate the earliest divergence. Treat “a health warning being dismissed without checking whether data redundancy is reduced” as a hypothesis until the same test passes after correction and under a boundary condition.

Validation Checklist

• The scope of Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning is clear, including what is deliberately excluded from the test.
• Evidence in vSAN monitoring checklist and learner action plan supports each material decision and outcome.
• A negative test demonstrates that controls reject or expose an invalid condition.
• Open risks, owners, due actions, and production safeguards are documented.

Lesson Outcome

Learners can apply Health service, performance basics, capacity views, alerts, disk faults, network issues, support bundles, backup concepts, upgrades, and next-step learning, explain the decisions made, and defend the result with vSAN monitoring checklist and learner action plan.
