VMware Performance and Capacity Management, Second Edition - Second Edition

By: Sunny Dua

Overview of this book

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.

Management changes in SDDC


I stated earlier that the very thing you manage has changed. SDDC changes the architecture of data centers, turning operation as usual from best practice to dated practice. The following table explains the operations in more detail so that we can see the impact on a specific discipline:

Performance management

This is actually a brand new discipline in itself. As you will see in Chapter 4, Performance Monitoring, it is not what you think it is.

This gets harder as the performance of ESXi, VM, and datastores can impact one another. The entire environment is no longer static. VM activities such as vMotion, Storage vMotion, provisioning, and power on also add to the workload. So, there is VM workload and infrastructure workload. Performance issues can originate from any component.

Troubleshooting something that is dynamic is difficult. Unlike a physical data center, the first thing we need to check is the overall health, because of the interdependency...
