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

Pluggable Storage Architecture (PSA)


Pluggable Storage Architecture (PSA) is a modular storage management framework, which was introduced with VMware vSphere 5. It has a plugin framework, which can be used by third party vendors to create Multipathing plugins, which can leverage array-specific Multipathing, load balancing, or failover features. VMware has its own default Multipathing plugin called the Native Multipathing Plugin (NMP):

Since, third party plugins are beyond the scope of this book, we will delve deeper into the components and functions of VMware NMP.

Every storage device detected by the ESXi host will be associated with a Multipathing plugin (MPP). This is achieved with the help of a claim rule. If there aren't any claim rules for a third party MPP, then the VMware NMP will claim the device and associate an SATP and PSP to it.

VMware NMP has two main components:

  • Storage Array Type Plugin (SATP)

  • Path Selection Plugin (PSP)

SATP is responsible for keeping a tab on the status of...
