Overview of this book

VMware vSphere PowerCLI, a free extension to Microsoft Windows PowerShell, enables you to automate the management of a VMware vSphere or vCloud environment. This book will show you how to automate your tasks and make your job easier. Starting with an introduction to the basics of PowerCLI, the book will teach you how to manage your vSphere and vCloud infrastructure from the command line. To help you manage a vSphere host overall, you will learn how to manage vSphere ESXi hosts, host profiles, host services, host firewall, and deploy and upgrade ESXi hosts using Image Builder and Auto Deploy. The next chapter will not only teach you how to create datastore and datastore clusters, but you’ll also work with profile-driven and policy-based storage to manage your storage. To create a disaster recovery solution and retrieve information from vRealize Operations, you will learn how to use Site Recovery Manager and vRealize Operations respectively. Towards the end, you’ll see how to use the REST APIs from PowerShell to manage NSX and vRealize Automation and create patch baselines, scan hosts against the baselines for missing patches, and re-mediate hosts. By the end of the book, you will be capable of using the best tool to automate the management and configuration of VMware vSphere.

Preface

Using VMware vSAN


VMware vSAN is a shared storage solution for Hyper-Converged Infrastructure (HCI) that uses local disks in ESXi servers as the media. A vSAN cluster consists of two or more ESXi hosts. Although two hosts is the minimum number required, VMware recommends using at least four hosts in a vSAN cluster. The local disks in an ESXi server can be combined into disk groups that can be all-flash or a combination of magnetic disks and flash devices, also named solid state drives or SSDs. There can be a maximum of seven disks per disk group. There is also a maximum of five disk groups on a host. At least one disk in a disk group must be SSD. SSDs will be used for read-and-write cache. Magnetic disks will be used for capacity storage. In an all-flash disk group, the SSDs in the cache tier are only used for write caching. The disk groups in a cluster are combined into a vSAN datastore named vsanDatastore. Also, hosts without a disk group can participate in a vSAN cluster. For vSAN communication...
