Mastering VMware vSphere Storage

By: Victor Wu, Eagle Huang

Overview of this book

<p>vSphere Storage is one of the three main infrastructure components of a vSphere deployment (Compute, Storage, and Network).</p> <p>Mastering VMware vSphere Storage begins with an insightful introduction to virtualization and creating your own virtual machines. We then talk about VMware vCenter Server and virtual machine management, as well as managing vSphere 5 using vSphere Management Assistant (vMA) and esxcli and vmware-cmd commands. We then swiftly move on to a very interesting topic, reviewing the vSphere performance and troubleshooting methodology. We then configure VM storage profiles, Storage DRS, and Storage I/O control. More significantly, we will troubleshoot and analyze storage using the VMware CLI and learn how to configure iSCSI storage.</p> <p>By the end of the book, you will be able to identify useful information to make virtual machine and virtual data center design decisions.</p>

Chapter 3. Using the Virtual Machine Monitor

Performance monitoring in a virtual machine is different from that in a traditional physical server. The virtual machine monitor (VMM) is a key component of the VMware vSphere environment, which is a thin layer that provides virtual x86 hardware for virtual machines' (VM) guest operating systems. VMware administrators are needed in order to know how to find performance problems using vSphere monitoring tools. VMware vCenter Server's performance charts and resxtop commands, which are common tools, can help you find performance problems in the vSphere Server.

In this chapter, we will cover the following topics:

  • The components of the VMware vSphere ESXi architecture

  • What the virtual machine monitor is

  • The difference between software and hardware virtualization techniques

  • Using vSphere Performance monitoring tools
