VMware vSAN: Install, Configure, Manage [V8] — Lesson 1: vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites

Learning Objectives

• Translate a realistic infrastructure or application requirement into an executable approach for vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites.
• Use vSAN readiness assessment and hardware-compatibility record to verify configuration, connectivity, security, and expected behavior.
• Explain how to recover safely when an unsupported controller firmware introducing instability during resynchronization occurs.

Detailed Topics

• VSAN architecture
• Original storage architecture and ESA concepts
• Hardware compatibility
• Disk groups
• Cache and capacity devices
• Networking
• Licensing
• And design prerequisites
• Decision ownership, prerequisites, and acceptance evidence for vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites
• Relevant access, security, capacity, dependency, performance, recovery, and support considerations

Instructor Demonstration

The demonstration traces vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites from requirement through execution and review. Learners see where evidence should be collected, how vSAN readiness assessment and hardware-compatibility record supports validation, and which warning signs require investigation.

Hands-On Exercise

Complete a guided task covering vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites. Establish a working baseline, reproduce “an unsupported controller firmware introducing instability during resynchronization,” isolate the responsible configuration or dependency, apply a reversible fix, and update vSAN readiness assessment and hardware-compatibility record with before-and-after proof.

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 architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how vSAN readiness assessment and hardware-compatibility record should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Avoid changing multiple settings at once while troubleshooting vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites. Preserve the failing example, review vSAN readiness assessment and hardware-compatibility record, and verify whether “an unsupported controller firmware introducing instability during resynchronization” is the root cause. After remediation, confirm downstream effects and add a monitoring action.

Validation Checklist

• Prerequisites and role permissions for vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites are confirmed before execution.
• The observed result agrees with expected values documented in vSAN readiness assessment and hardware-compatibility record.
• 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 vSAN architecture, original storage architecture and ESA concepts, hardware compatibility, disk groups, cache and capacity devices, networking, licensing, and design prerequisites, explain the decisions made, and defend the result with vSAN readiness assessment and hardware-compatibility record.
