Mastering PowerCLI

By: Sajal Debnath

Overview of this book

Have you ever wished that every morning you could automatically get a report with all the relevant information about your datacenter in exactly the same format you want? Or whether you could automate that boring, exhausting task? What if some crucial task needs to be performed on a regular basis without any error? PowerCLI scripts do all that and much more for VMware environments. It is built on top of the popular Windows PowerShell, with which you can automate server tasks and reduce manual input, allowing you to focus on more important tasks. This book will help you to achieve your goals by starting with a short refresher on PowerShell and PowerCLI and then covering the nuances of advanced functions and reusable scripts. Next you will learn how to build a vSphere-powered virtualized datacenter using PowerCLI while managing different aspects of the environment including automated installation, network, and storage. You will then manage different logical constructs of vSphere environment and different aspects of a virtual machine. Later, you will implement the best practices for a security implementation in vSphere Environment through PowerCLI before discovering how to manage other VMware environments such as SRM, vCloud Director and vCloud Air through PowerCLI. You will also learn to manage vSphere environments using advanced properties by accessing vSphere API and REST APIs through PowerCLI. Finally, you will build a Windows GUI application using PowerShell followed by a couple of sample scripts for reporting and managing vSphere environments with detailed explanations of the scripts. By the end of the book, you will have the required in-depth knowledge to master the art of PowerCLI scripting.

Configuring vSphere network I/O control


Configuring network I/O control in the vSphere environment is a great way to control and ensure quality of service for different types of traffic. Though there is no direct cmdlet available to enable and disable network I/O control using PowerCLI, we can do so using the vSphere APIs using PowerCLI. We can get a list of all the methods and properties available in the VDSwitch object by inspecting the ExtensionData option of the object. In the following screenshot, we can see that there is an EnableNetworkResourceManagement method associated with the object that takes a $true or $false Boolean input, which decides whether NetworkResourceManagement will be turned on or off.

Tip

We will see how we can access APIs using PowerCLI in the upcoming chapter in detail. For now, we will just touch upon the subject.

So, we can enable or disable network I/O control by simply using the following method:

PS C:\> (Get-VDSwitch -Name Test1).ExtensionData.EnableNetworkResourceManagement...
