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

Enhanced Linked Mode


As you already know, vCenter enables centralized management of your core vSphere infrastructure. In large environments there can be more than one vCenter server deployed to manage the resources, it is beneficial to view all the vCenter inventories from a single management plane. This can be achieved using Enhanced Linked Mode.

Enhanced Linked Mode enables the linking of more than one vCenter Server, be it vCenter installed on a Windows machine or the VCSA. Although it is referred to as a method to link vCenter servers together, the actual linking happens between the Platform Service Controllers the vCenters are connected to. It is done so by making the PSCs join a single SSO domain. This is a requirement. The PSCs in the same SSO domain will replicate roles and permissions, licenses, and other details letting the administrator perform a single login into the vSphere Web Client to view and manage inventory objects of all the linked vCenter servers.
