VMware vSAN: Install, Configure, Manage [V7] — Lesson 2: vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains

Learning Objectives

• Translate a realistic infrastructure or application requirement into an executable approach for vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains.
• Use cluster build record and network communication test to verify configuration, connectivity, security, and expected behavior.
• Explain how to recover safely when one host advertising vSAN traffic through a nonroutable vmkernel interface occurs.

Detailed Topics

• VSAN networking
• Vmkernel adapters
• Cluster configuration
• Disk claiming
• Services
• Datastore creation
• Health checks
• Performance service
• And fault domains
• Decision ownership, prerequisites, and acceptance evidence for vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

Using realistic infrastructure, identities, and workloads, the instructor demonstrates vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains. Checkpoints are captured in cluster build record and network communication test, with discussion of alternatives, side effects, and acceptance conditions.

Hands-On Exercise

Work through a role-based scenario involving vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains. Validate the expected path, test “one host advertising vSAN traffic through a nonroutable vmkernel interface,” choose the safest corrective action, and capture the reasoning and outcome in cluster build record and network communication test.

1. Define the requirement and identify dependencies before changing the environment.
2. Create a baseline result that can be compared with later changes.
3. Reproduce the exception and test one hypothesis at a time.
4. Complete the evidence record and obtain peer or instructor review.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how cluster build record and network communication test should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

For a failure in vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains, separate access, configuration, compute, network, storage, integration, and timing causes. Compare the observed sequence with cluster build record and network communication test; if “one host advertising vSAN traffic through a nonroutable vmkernel interface” is confirmed, document why broader changes were rejected.

Validation Checklist

• Configuration and source state used for vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains are versioned or otherwise traceable.
• Cluster build record and network communication test shows both baseline and accepted result.
• Security, performance, dependency, and resilience side effects are considered where relevant.
• Recovery steps and handover notes are usable by an operations practitioner.

Lesson Outcome

Learners can apply vSAN networking, vmkernel adapters, cluster configuration, disk claiming, services, datastore creation, health checks, performance service, and fault domains, explain the decisions made, and defend the result with cluster build record and network communication test.
