Preface
VMware VSAN is a phenomenal concept, technology, solution, and a product—all in one—that has redefined storage provisioning and management in a vSphere-backed infrastructure. The complexities of the traditional SAN have been replaced with simpler, agile, and scalable storage; the key differentiator with VSAN is the fact that complete control of the storage is at the software stack, truly aligning it with the software-defined datacenter vision.
While VSAN has been made simpler, it still needs to be understood and configured appropriately for optimal outcome. With this book, you will be able to understand, deploy, optimize, and monitor a VSAN-backed infrastructure. Based on various use cases and business needs, you will also be able to define appropriate SLAs and ensure compliance through policies.
Besides administration, you will understand what goes on beneath the surface in terms of the architecture and get an explanation of the components that make up VSAN. This helps in closely understanding the limitations of the product and also equips you to analyze and troubleshoot issues that may surface due to anomalies.
This book discusses the first generation of VSAN, as well as its successors, clearly explaining the refinements made in the newer releases to understand the trade-offs with each version.
What this book covers
Chapter 1, An Introduction to Software-defined Storage and VSAN, discusses some fundamental aspects of software-defined storage, its evolution, and its role in SDDC. You will also get an overview and basic understanding of VMware Virtual SAN.
Chapter 2, Understanding Virtual SAN, discusses Virtual SAN at a high level and builds a basic understanding of how it is put together.
Chapter 3, Workload Profiling and Sizing, talks about the generic guidelines pertaining to sizing and profiling of Virtual Machines.
Chapter 4, Getting Started with VSAN – Installation and Configuration, demonstrates deploying a simple set up to show the workflow of a typical VSAN deployment.
Chapter 5, Truly Software-defined, Policy-based Management, discusses one of the unique differentiators of Virtual SAN called Storage Policy-Based Management (SPBM).
Chapter 6, Architecture Overview, explains why VSAN has a relatively complex architecture and then discusses the structure and components of VSAN.
Chapter 7, Design Considerations and Guidelines, talks about some of the design considerations and best practices to fine-tune the configuration and ensures optimal performance and availability.
Chapter 8, Troubleshooting and Monitoring Utilities for Virtual SAN, provides a configuration overview, and helps you in assuring the health of the infrastructure and proactively monitoring key metrics and potential issues.
Chapter 9, What's New in VSAN 6.0?, assesses the newer features, enhancements, and architectural changes with the second generation of VSAN.

Chapter 1. An Introduction to Software-defined Storage and VSAN
In this chapter, you will learn some fundamental aspects of Software-defined Storage, its evolution, and its role in a Software-defined Data Center. You will also get an overview and a basic understanding of VMware Virtual SAN.
To understand the transformation that is taking place in modern data center, we will discuss:
What is a Software-defined Data Center?
Virtualization has come a long way in terms of evolution and dates back to 1960, where mainframes first supported virtualization.
Decades later, leading into the x86 era, there was a strong need to leverage the virtualization concept on a x86 platform. The need was straight and simple, a transition from an application/operating system per server to running multiple such instances per server. The reasons were obvious as well, server hardware capabilities had increased exponentially and much of the server resources were wasted. There was room for the consolidation and optimization of resources, and needless to say, this also meant significant return on investment.
While there were a few players who threw their hats into the ring, not many made a mark. In the year 1998, however, VMware was established and their first product, Workstation,
