Mastering VMware vSAN 9.1: Build and Manage Resilient Virtualization Infrastructure with ESA, Storage Policies, High Availability, Performance, Capacity Planning, Troubleshooting

Master VMware vSAN 9.1 and Build Virtualization Infrastructure You Can Trust Modern virtual infrastructure requires more than powerful servers. It needs reliable storage, strong protection, predictable performance, scalability, and the ability to recover when things go wrong. Mastering VMware vSAN 9.1 provides a practical, beginner-friendly guide to designing, deploying, managing, optimizing, and troubleshooting VMware vSAN environments. >The book takes you from fundamentals to real-world administration, including vSAN Express Storage Architecture (ESA) and Original Storage Architecture (OSA), hardware and networking requirements, capacity planning, storage protection, performance optimization, high availability, and disaster recovery. Inside, you'll learn how to: - Understand vSAN 9.1 architecture and HCI- Design and deploy production-ready vSAN clusters- Work with vSAN ESA and OSA- Plan servers, NVMe devices, networking, and capacity- Configure Storage Policy-Based Management (SPBM)- Understand RAID-1, RAID-5, RAID-6, FTT, and failure domains- Use ESA Auto-RAID, compression, and deduplication- Build highly available environments with vSphere HA- Handle host, storage-device, and network failures- Understand resynchronization, rebuilds, maintenance, and recovery- Design stretched clusters and site-level resilience- Improve IOPS, latency, throughput, and workload performance- Monitor vSAN health, capacity, performance, and devices- Troubleshoot degraded objects, storage, networking, and performance issues- Plan backups, replication, disaster recovery, and business continuity- Manage lifecycle operations, upgrades, and cluster expansion- Design vSAN for enterprise, VDI, database, and mixed workloads Beyond configuration steps, this book teaches you how to think like a vSAN administrator. You'll learn to evaluate protection, capacity, performance, failure domains, and recovery requirements before making infrastructure decisions. When problems occur, you'll follow a systematic troubleshooting approach: observe the environment, identify the actual cause, apply controlled corrective action, and verify the result. Whether you're new to VMware vSAN or managing an existing environment, this guide will help you build the knowledge needed to design, operate, troubleshoot, and scale reliable vSAN infrastructure. By the end, you'll have a practical understanding of VMware vSAN 9.1, ESA architecture, storage protection, performance optimization, high availability, capacity planning, and real-world troubleshooting-from initial design to production operations.
