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

Storage DRS


Much like ESXi hosts, the VMFS datastores can be grouped to form a datastore cluster. This helps in enabling the Storage Distributed Scheduler on it to ease datastore management.

Like with the clustering of the compute resource, datastore clusters will also need to meet certain requirements. Here are some of the most important ones:

  • The datastores in a datastore cluster should only be accessible to ESXi hosts from a single data center (vCenter Data Center inventory object)

  • A single datastore cluster cannot contain both VMFS and NFS volumes

  • All the ESXi hosts accessing the datastores should be of version ESXi 5.0 or higher

  • Additional requirements are listed in the vSphere 6 Resource Management Guide on page-91

The following procedure will guide you through the steps required to create a datastore cluster and enable Storage DRS on it:

  1. Connect to the vCenter Server and navigate to Home | Storage.

  2. Right-click on the datacenter in...
