СКАЧАТЬ environment. I also discuss backup options using vSphere’s Storage APIs.

      Chapter 8: Securing VMware vSphere

      Security is an important part of any implementation, and in this chapter I cover different security management aspects, including managing direct ESXi host access and integrating vSphere with Active Directory. This chapter also covers how to manage user access for environments with multiple levels of system administration and how to employ Windows users and groups in conjunction with the vSphere security model to ease the administrative delegation that comes with enterprise-level deployments.

      Chapter 9: Creating and Managing Virtual Machines

      This chapter introduces the practices and procedures involved in provisioning virtual machines through vCenter Server. In addition, you’re introduced to timesaving techniques, virtual machine optimization, and best practices that will ensure simplified management as the number of virtual machines grows larger over time.

      Chapter 10: Using Templates and vApps

      Chapter 10 introduces the idea of templates, a mechanism for more rapidly deploying standardized VM images. I also discuss cloning and the concept of a vApp – a specialized container used by vSphere for the distribution of multi-VM environments. In addition, I discuss the OVF standard used by VMware and other vendors for distributing VMs.

      Chapter 11: Managing Resource Allocation

      In this chapter I provide a comprehensive look at managing resource allocation. From individual virtual machines to resource pools and clusters of ESXi hosts, this chapter explores how resources are consumed in vSphere and addresses the mechanisms you can use – reservations, limits, and shares – to manage and modify that resource allocation.

      Chapter 12: Balancing Resource Utilization

      Resource allocation isn’t the same as resource utilization, and this chapter follows up the discussion of resource allocation in Chapter 11 with a look at some of the ways vSphere offers to balance resource utilization. In this chapter, you’ll learn about vSphere vMotion, Enhanced vMotion Compatibility, vSphere Distributed Resource Scheduler (DRS), Storage vMotion, and Storage DRS.

      Chapter 13: Monitoring VMware vSphere Performance

      In Chapter 13 I look at some of the native tools in vSphere that give virtual infrastructure administrators the ability to track and troubleshoot performance issues. The chapter focuses on monitoring CPU, memory, disk, and network adapter performance across ESXi hosts, resource pools, and clusters in vCenter Server. In this chapter you’ll also learn about vCenter Operations Manager.

      Chapter 14: Automating VMware vSphere

      Many tasks VMware vSphere administrators face are repetitive, and here automation can help. In Chapter 14 we discuss several different ways to bring automation to your vSphere environment, including vCenter Orchestrator and PowerCLI.

      Appendix: The Bottom Line

      This appendix offers solutions to the Master It problems at the end of each chapter.

      The Mastering Series

      The Mastering series from Sybex provides outstanding instruction for readers with intermediate and advanced skills, in the form of top-notch training and development for those already working in their field and clear, serious education for those aspiring to become pros. Every Mastering book includes the following:

      • Real-World Scenarios, ranging from case studies to interviews, that show how the tool, technique, or knowledge presented is applied in actual practice

      • Skill-based instruction, with chapters organized around real tasks rather than abstract concepts or subjects

      • Self-review test questions, so you can be certain you’re equipped to do the job right

      The Hardware behind the Book

      Starting out, it can seem difficult to build an environment in which you can learn by implementing the exercises and practices detailed in this book. It is possible to build a practice lab with minimal hardware, and I encourage you to follow along with the book. If you’re just starting, I recommend building a nested virtual lab on your laptop or desktop computer. Head to www.labguides.com for details on AutoLab, a nested vSphere automation tool. It needs VMware Workstation or Fusion installed and 16 GB of RAM. Be sure to read Chapters 2 and 3 before you attempt to construct any type of environment for development purposes.

      For the purpose of writing this book, I used multiple hardware configurations. When I was on the road I spun up a simple nested lab on my laptop using AutoLab, but at home I used a decent setup with a number of servers and storage that I change around when needed. I keep an updated list of recommended lab component details with multiple price options at www.labguides.com/guides/hardware/.

      It’s not impossible to set yourself up with a nice lab to follow along. But for some, this is not the sort of environment to which they have access. For entry-level NFS and iSCSI testing, a number of vendors, including EMC, HP, and NetApp, offer virtual storage appliances or simulators that you can use to gain some familiarity with shared storage concepts and that specific vendor’s products. I encourage you to use these sorts of tools where applicable in your learning process.

      Who Should Buy This Book

      This book is for IT professionals looking to strengthen their knowledge of constructing and managing a virtual infrastructure on vSphere 6.0. While the book can also be helpful for those new to IT, a strong set of assumptions is made about the target reader:

      • A basic understanding of networking architecture

      • Experience working in a Microsoft Windows environment

      • Experience managing DNS and DHCP

      • A basic understanding of how virtualization differs from traditional physical infrastructures

      • A basic understanding of hardware and software components in standard x86 and x64 computing

      Introducing VMware vSphere 6

      Now in its sixth generation, VMware vSphere builds on previous generations of VMware’s enterprise-grade virtualization products. vSphere 6.0 extends fine-grained resource allocation controls to more types of resources, enabling you to have even greater control over how resources are allocated to and used by virtual workloads. With dynamic resource controls, high availability, unprecedented and further improved fault-tolerance features, distributed resource management, and backup tools included as part of the suite, IT administrators have all the tools they need to run an enterprise environment ranging from a few servers to tens of thousands of servers.
