VMware vSAN: Install, Configure, Manage [V7] — Lesson 1: vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites

Learning Objectives

• Break down the prerequisites, components, roles, and decision points involved in vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites.
• Complete a controlled activity for vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites and capture vSAN prerequisite assessment and logical architecture diagram.
• Challenge the result with an unsupported storage controller mode invalidating the planned deployment, then justify the corrective action.

Detailed Topics

• VSAN concepts
• Architecture
• Disk groups
• Object components
• Witness behavior
• Hardware compatibility
• Licensing
• Network design
• Capacity
• And cluster prerequisites
• Decision ownership, prerequisites, and acceptance evidence for vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The instructor builds a representative scenario for vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites, narrating each decision and showing how it contributes to a correctly installed and managed vSAN 7 environment with compliant policies, resilient object placement, validated performance, secure configuration, and support-ready operations. The demonstration records vSAN prerequisite assessment and logical architecture diagram so learners can compare design intent with observable behavior.

Hands-On Exercise

Build or execute vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites for a defined scenario. Introduce the condition “an unsupported storage controller mode invalidating the planned deployment,” inspect the evidence, correct the cause without discarding the audit trail, and document the accepted state in vSAN prerequisite assessment and logical architecture diagram.

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 vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how vSAN prerequisite assessment and logical architecture diagram should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

When vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites produces an unexpected result, reproduce the issue with the same scope, identity, workload, and time context. Inspect vSAN prerequisite assessment and logical architecture diagram, test whether “an unsupported storage controller mode invalidating the planned deployment” explains the evidence, apply the smallest reversible correction, and retest an unaffected path for regression.

Validation Checklist

• The requirement for vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites is linked to an owner and observable acceptance condition.
• Vsan prerequisite assessment and logical architecture diagram contains enough detail for another practitioner to repeat the check.
• Normal operation, one boundary condition, and the identified failure path have been tested.
• Access, security, downstream impact, rollback, monitoring, and support ownership are recorded.

Lesson Outcome

Learners can apply vSAN concepts, architecture, disk groups, object components, witness behavior, hardware compatibility, licensing, network design, capacity, and cluster prerequisites, explain the decisions made, and defend the result with vSAN prerequisite assessment and logical architecture diagram.
