PowerCLI Cookbook

Chapter 2. Configuring vCenter and Computing Clusters

In this chapter, you will cover the following topics:

  • Creating a virtual datacenter in vCenter
  • Creating a cluster and adding ESXi hosts
  • Setting cluster advanced features, including HA, DRS, and EVC
  • Setting up resource pools
  • Setting up folders to organize objects in vCenter
  • Setting permissions on vCenter objects

Introduction

A single ESXi host allows you to run multiple virtual machines on a single server, but to tap the full potential of power from vSphere, you're going to need vCenter and clusters of ESXi hosts. This chapter will cover the basic concepts of creating and managing pools of resources using vCenter and multiple ESXi hosts.

vCenter is an increasingly critical part of the vSphere infrastructure since it handles the coordination of clustering and automation across multiple ESXi hosts. This drives the change and increases the complexity of vCenter deployments in each new version of vSphere. Even while the vCenter deployments are becoming more complex, VMware is working to try and ease that management by packaging the solution in simpler ways. vSphere 5.1 introduced the new Single Sign-On (SSO) service to the platform, and vSphere 5.5 streamlined deployment of the SSO's second version in vSphere. vSphere 5.5 also improved the virtual appliance version of vCenter, known as the...

Creating a virtual datacenter in vCenter

vSphere has several defined objects that are used to create virtual datacenters. For example, an object named Datacenter sits at the root of vSphere and allows the clusters and other host infrastructures to be placed inside the virtual datacenter. Installations might have multiple datacenters; however, most VMware administrators use additional datacenter objects in vSphere to represent a physical site and use the datacenter object as a boundary where the infrastructure exists. In this recipe, you will take a look at the code needed to create your new datacenter object in vCenter.

Getting ready

For this recipe, you will need to open a PowerCLI prompt, you need the DNS name or IP address of your vCenter host, and the password for the default administrator account in vCenter.

How to do it…

In order to create a virtual datacenter, and to create new datacenter object in vCenter, perform the following steps:

  1. The first step is to connect to your vCenter...

Creating a cluster and adding ESXi hosts

Clusters are the basis for everything that is great within vSphere. Clusters are the level where individual resources become pooled and shared for virtual machines. Clusters allow all higher-level functionalities within vSphere, such as an automatic restart after a hardware failure and dynamic balancing of workloads. Individual ESXi hosts and clusters can exist at the same level under a datacenter object in vSphere.

In this recipe, you will walk through the steps necessary to set up your first cluster of servers in vCenter. You will be reusing the same four ESXi hosts that you configured in the Creating a configuration script to set all properties uniformly recipe from Chapter 1, Configuring the Basic Settings of an ESXi Host with PowerCLI.

Getting ready

This chapter assumes that your vCenter has the datacenter object defined and that you have individual ESXi hosts connected or managed by vCenter. In this example, you will call the Primary datacenter...

Setting cluster advanced features, including HA, DRS, and EVC

The previous recipe mentioned the advanced features of vSphere clusters. In this recipe, you will configure those advanced features since it is more common to reconfigure these settings than to initially set these settings.

The cluster settings you are going to be working with are HA, DRS, and Enhanced vMotion Compatibility (EVC) settings. In the vSphere Client, these settings are exposed in the Edit Cluster Settings option.

Creating a cluster is a one-time event, but as you deploy vSphere, you might not be ready to automate vMotions or Storage vMotions with DRS in your cluster from the beginning.

However, over a period of time, your comfort level with these automation technologies begins to increase and you would want to put the cluster on autopilot and change the automation level to be fully automated. You will cover how to do this and how to set up other common settings from PowerCLI.

PowerCLI is useful for these settings because...

Setting up resource pools

Resource pools are objects within vSphere where VM objects with similar performance requirements can be grouped together. Resource pools allow a priority to be set to pools of compute, memory, and disk resources, so that when the contention occurs, the hypervisor can choose which VMs get access to resources first. Resource pools exist within the cluster objects in vSphere or within host objects if a host is not a part of a cluster.

Getting ready

To begin this recipe, you will need to open a PowerCLI window and connect to a vCenter server. For the purpose of this example, we're going to configure two resource pools: Production and Development. The Production resource pool will be configured with the high setting for CPU and memory resources. The Development resource pool will be configured with the low setting for CPU and memory resources.

Sometimes, PowerCLI defines its normal conventions and resource pools is one of them. You can't simply pass a cluster...

One of the more difficult parts of learning PowerCLI - and PowerShell itself - is determining where to get started. I often suggest identifying a project or task that you want to complete, and then figuring out how to do it, because aimlessly fiddling with a language can be frustrating. If you're looking for a library of sample code that walks you through the why and how, I'd suggest picking up the PowerCLI Cookbook written by Philip Sellers.The book is published through Packt Publishing, who's library contains material that wildly varies across the quality spectrum. However, it is obvious that Philip put a large quantity of time, effort, and care into this book and offers over 200 pages of in-depth discussion and examples for automating a wide swath of data center activities.Each walk-through is arranged into a recipe, containing details on what will be required to follow along with the recipe, steps required to build the code, details on why the code is setup the way it is (and how to modify it for your own purposes). The author has frequently added additional reading to the recipes with blog links, documentation, KBs, and other handy resources.Of note, Philip has built a fairly robust set method for balancing share allocations and resource pools using some of my older work as a baseline. Don't worry, he pinged me about it before it made it into the book, but his approach of using a custom attributes (page 140) is refreshing and looks solid. He even writes a proper function whereas my code was just a spitball idea.There's also an entire section on snapshot management (page 107) with the steps necessary to build a snapshot management module (page 129). I've talked about PowerShell modules recently, and it's spectacular to see examples on building custom modules in this book. Philip offers ideas around naming of snapshots, when to quiesce memory, and how to automate / prune the snapshot lifecycle. This is solid stuff.The last thing I'll compliment is the points in the book where Philip goes a bit out of scope of a straight cookbook. For example, on page 78 there's a decent volume of content covering the use of Get-View and how to view properties and methods. That's some pretty advanced stuff, but the writing breaks it down into meaningful and digestible chunks. Having hit the limitation of the native PowerCLI cmdlets frequently, there's definitely a lot of value in knowing how to leverage methods directly.If you're brand new to PowerCLI, or looking to leverage some polished examples to help tickle the noodle on coding ideas, I'd suggest picking up a copy of PowerCLI Cookbook. I read the whole thing over the course of a few plane flights because it was that good.Note: I requested a review copy of the book from the author which was fulfilled by the publisher.

I am a virtualization engineer with 9 years of experience creating automation and administration solutions for large corporations.Last year I was contacted by Packt Publishing and asked if I would be interested in providing technical review services for a new book titled PowerCLI Cookbook. It seemed like an excellent opportunity and I quickly agreed.They sent me a draft copy of the book, one chapter at a time. I would review the chapter content for technical accuracy and test each of the chapter’s code samples and downloadable content, and reply with any corrections, my comments and any feedback. I quickly realized that reading a technical book is a lot different than reviewing a technical book. However I still enjoyed the process as It gave me a chance to use (and expand) my skills in a fun new way.Chapter by chapter, I reviewed the book. I found each chapter to be filled with powerful examples, showing ways to simplify and automate the real tasks that vSphere administrators need to do, the real tasks that I need to do. I finished my review of the last chapter back in early November .Well, Packt has finally published the PowerCLI Cookbook.They wanted to give the author time to validate and update the book’s content to include the vSphere 6 feature set.With a published copy in hand, and based on my detailed review of the book’s content, I can tell you with confidence that Philip Sellers has delivered an excellent resource on PowerCLI, and I highly recommend it to anyone looking for such a resource.The book details examples of dozens of highly useful, real world tasks needed for the day-to-day administration of your vSphere environment. The examples are presented in a way that lets your quickly learn to use and adapt them to your needs.Whether you are new to PowerCLI and looking for a book to help you learn and get started, or you are an experienced PowerShell or PowerCLI user looking for a great reference book to help you automate the administration of your virtual environment, you will find this book to be an excellent choice.

I’m glad I purchased this book! I’ve already found several topics that I’ve needed to get into my production routine. The book is put together very well with straight forward approaches covering what I and many administrators need every day for administration. Scripting and automation are life savers (no longer optional, but required). I believe I’ve already recouped my investment by just using the recipes presented and I’ve only just begun.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
