VMware Performance and Capacity Management, Second Edition - Second Edition

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.

VMware VSAN


The preceding discussion applies to a classic physical array. Let's take a look at distributed storage. By distributed storage, we mean a storage architecture that uses local disks from servers to form virtual shared storage. There is no physical storage anymore. There are multiple ways to achieve this, and there are enough differences among the distributed storage products.

The differences result in different approaches for performance and capacity management. In this book, we will cover VMware Virtual SAN (VSAN). You should not assume that you can apply the solution here to monitor other distributed storage products. Even within VSAN, there are differences in monitoring a hybrid VSAN and all-flash VSAN.

Note

Read Chapter 16, VMware Virtual SAN Diagnostics and Troubleshooting Reference Manual by Cormac Hogan (http://www.vmware.com/files/pdf/products/vsan/VSAN-Troubleshooting-Reference-Manual.pdf).

Let's see how monitoring VSAN differs from monitoring classic storage. As usual, we...
