VMware Performance and Capacity Management, Second Edition

Chapter 1. VM – It Is Not What You Think!

In this chapter, we will dive into why a seemingly simple technology, a virtualized x86 machine, has huge ramifications for the IT industry. In fact, it is turning a lot of things upside down and breaking down silos that have existed for decades in large IT organizations. We will cover the following topics:

Why virtualization is not what we think it is
Virtualization versus partitioning
A comparison between a physical server and Virtual Machine

Physical server versus Virtual Machine

Hopefully, I've driven home the point that a VM is different from a physical server. I'll now list the differences from a management point of view. The following table shows the differences that impact how you manage your infrastructure. Let's begin with the core properties:

Properties

Physical server

Virtual Machine

BIOS

Every brand and model has a unique BIOS. Even the same model (for example, HP DL 380 Generation 9) can have multiple BIOS versions.

The BIOS needs updates and management, often with physical access to a data center. This requires downtime.

This is standardized in a VM. There is only one type, which is the VMware motherboard. This is independent from the ESXi motherboard.

The VM BIOS needs far fewer updates and management. The inventory management system no longer needs the BIOS management module.

Virtual HW

Not applicable.

This is a new layer below the BIOS.

It needs an update after every vSphere release...

Key benefits

Understand the drawbacks of the traditional paradigm and management that make operations difficult in SDDC
Master performance and capacity management in Software-Defined Data Center
Operationalize performance and capacity monitoring with proven dashboards

Description

Performance management and capacity management are the two top-most issues faced by enterprise IT when doing virtualization. Until the first edition of the book, there was no in-depth coverage on the topic to tackle the issues systematically. The second edition expands the first edition, with added information and reorganizing the book into three logical parts. The first part provides the technical foundation of SDDC Management. It explains the difference between a software-defined data center and a classic physical data center, and how it impacts both architecture and operations. From this strategic view, it zooms into the most common challenges—performance management and capacity management. It introduces a new concept called Performance SLA and also a new way of doing capacity management. The next part provides the actual solution that you can implement in your environment. It puts the theories together and provides real-life examples created together with customers. It provides the reasons behind each dashboard, so that you get the understanding on why it is required and what problem it solves. The last part acts as a reference section. It provides a complete reference to vSphere and vRealize Operations counters, explaining their dependencies and providing practical guidance on the values you should expect in a healthy environment.

Who is this book for?

This book is primarily for any system administrator or cloud infrastructure specialist who is interested in performance management and capacity management using VMware technologies. This book will also help IT professionals whose area of responsibility is not VMware, but who work with the VMware team. You can be Windows, Linux, Storage, or Network team; or application architects. Note that prior exposure to the VMware platform of data-center and cloud-based solutions is expected.

What you will learn

Simplify the task of performance and capacity management
Master the counters in vCenter and vRealize Operations and understand their dependency on one another
Educate your peers and management on SDDC Operations
Complete your SDDC monitoring to include non-VMware components
Perform SDDC performance troubleshooting
Explore real-life examples of how super metric and advanced dashboards
Introduce and implement a Performance SLA
Accomplish your Capacity Management by taking into service tiering and performance SLA
