Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Datastore management


Once we have configured access to the storage array, we will need to form file system containers on them. The LUNs presented to an ESXi host, unless they are NFS exports, do not have any filesystems on it. Such a LUN is called a Raw LUN. ESXi can create a distributed file system on it called the Virtual Machine File System (VMFS). Once formed, a logical data container called a datastore is presented to the user world on the ESXi. Datastore is however, a common term to refer to VMFS volumes and NFS mounts. In this section of the chapter, we will learn how to create and manage datastores.

We will cover the following topics:

  • The virtual machine filesystem

  • Creating VMFS datastores

  • Managing the storage capacity of a datastore

  • Managing VMFS snapshots

The Virtual Machine File System

A raw storage device presented to an ESXi host can be formatted to host VMware's propriety file system called the Virtual Machine File System (VMFS). It is a matured file system, which is currently at...
