VMware vSAN: Introduction — Lesson 2: Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites

Learning Objectives

• Identify the architecture and operational choices that shape Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites.
• Run normal and boundary tests and record the outcome in basic readiness checklist and compatibility lookup record.
• Separate root cause from symptom when investigating an unsupported controller configuration being selected for a new cluster.

Detailed Topics

• Hardware compatibility
• Host requirements
• Storage controllers
• Device types
• Network interfaces
• Vmkernel traffic
• Bandwidth
• Latency
• And deployment prerequisites
• Decision ownership, prerequisites, and acceptance evidence for Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The instructor configures and tests Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites within a scenario aimed at a foundational understanding of vSAN architecture, hardware, networking, storage policies, object behavior, resilience, health, capacity, and everyday operational concepts. The walkthrough contrasts a valid setup with a flawed one and uses basic readiness checklist and compatibility lookup record to make the difference explicit.

Hands-On Exercise

Configure and test Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites with representative infrastructure or application data. Use “an unsupported controller configuration being selected for a new cluster” as the troubleshooting challenge, compare hypotheses, retest the affected path, and complete basic readiness checklist and compatibility lookup record for review.

1. Confirm scope, access, sample workloads, and acceptance criteria.
2. Perform the configuration or operation using a controlled sequence.
3. Inspect outputs and downstream effects rather than relying on task status alone.
4. Close with a support note, preventive action, and reproducible validation step.

Scenario Analysis

• Clarify the service trigger, affected components and roles, prerequisites, and acceptable result for Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how basic readiness checklist and compatibility lookup record should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

When Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites produces an unexpected result, reproduce the issue with the same scope, identity, workload, and time context. Inspect basic readiness checklist and compatibility lookup record, test whether “an unsupported controller configuration being selected for a new cluster” explains the evidence, apply the smallest reversible correction, and retest an unaffected path for regression.

Validation Checklist

• The scope of Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites is clear, including what is deliberately excluded from the test.
• Evidence in basic readiness checklist and compatibility lookup record 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 Hardware compatibility, host requirements, storage controllers, device types, network interfaces, vmkernel traffic, bandwidth, latency, and deployment prerequisites, explain the decisions made, and defend the result with basic readiness checklist and compatibility lookup record.
