VMware vSAN: Fast Track [V7] — Lesson 3: Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management

Learning Objectives

• Assess dependencies, controls, resilience, and the intended service outcome for Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management.
• Demonstrate the workflow and leave reproducible evidence in policy compliance report and maintenance-mode test.
• Recommend a preventive improvement after resolving entering maintenance with an option that cannot preserve object accessibility.

Detailed Topics

• Storage policies
• Failures to tolerate
• RAID methods
• Object placement
• Resynchronization
• Maintenance modes
• Deduplication
• Compression
• Encryption
• And capacity management
• Decision ownership, prerequisites, and acceptance evidence for Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The instructor builds a representative scenario for Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management, narrating each decision and showing how it contributes to a production-oriented vSAN 7 cluster designed, deployed, managed, secured, monitored, and troubleshot with evidence-based operational practices. The demonstration records policy compliance report and maintenance-mode test so learners can compare design intent with observable behavior.

Hands-On Exercise

Complete a guided task covering Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management. Establish a working baseline, reproduce “entering maintenance with an option that cannot preserve object accessibility,” isolate the responsible configuration or dependency, apply a reversible fix, and update policy compliance report and maintenance-mode test with before-and-after proof.

1. Map the current workflow and mark where the expected result can first be observed.
2. Run the scenario while preserving timestamps, object identifiers, and relevant output.
3. Apply a reversible correction only after evidence supports the cause.
4. Retest the original case plus an unaffected case and update the handover record.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how policy compliance report and maintenance-mode test should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

For a failure in Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management, separate access, configuration, compute, network, storage, integration, and timing causes. Compare the observed sequence with policy compliance report and maintenance-mode test; if “entering maintenance with an option that cannot preserve object accessibility” is confirmed, document why broader changes were rejected.

Validation Checklist

• Prerequisites and role permissions for Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management are confirmed before execution.
• The observed result agrees with expected values documented in policy compliance report and maintenance-mode test.
• Exceptions are explained with evidence instead of being hidden by manual correction.
• The final record names the approver, monitoring point, and next improvement action.

Lesson Outcome

Learners can apply Storage policies, failures to tolerate, RAID methods, object placement, resynchronization, maintenance modes, deduplication, compression, encryption, and capacity management, explain the decisions made, and defend the result with policy compliance report and maintenance-mode test.
