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

Configuring access to NFS storage


Like your iSCSI storage, NFS storage is also network attached and can easily be made a member of your data center infrastructure leveraging its current TCP/IP network. Unlike, iSCSI, NFS is not a block storage, meaning NFS runs and maintains its own file system. Hence, ESXi cannot format and form a new file system on the volumes presented to it from an NFS array. Instead, the NFS volumes, or rightly called exports, are just mount points on an ESXi host, to remote shares on an NFS storage array.

This section of the chapter will cover the procedures involved in configuring access to NFS shares on an NFS Storage.

What do we need?

The prerequisites needed for this task are:

  • We need access to the network segment the NFS storage is on. Hence, the ESXi host will need a Vmkernel interface in the same subnet as the NFS storage. To learn how to create a Vmkernel interface, refer to Chapter 4vSphere Networking Concepts and Management.

  • NFS shares should have the no_rootsquash...
