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

A virtual machine network interface (vNIC)


Every virtual machine will need a network interface card that can connect and participate in a network. VMware calls it a vNIC. These entities can be created on each virtual machine. There are different types of vNICs that can be created on a virtual machine. The type of vNIC you choose will not only depend on the type of guest operating system that runs on a virtual machine but also on the purpose of the NIC card. VMware allows adding up to 10 vNICs per virtual machine. All the vNICs that you add to a virtual machine can be of any supported type or even a combination of multiple NIC types.

The available vNIC adapter types are:

  • The vla adapter - this is the first version of vNIC and is an emulated version of AMD's 79C970 PCNET32 LANCE network adapters. Almost all traditional operating systems will have a driver bundle for this adapter. Hence, the installation of VMware tools is not necessary for the vNIC to function. The maximum speed supported by...
