Preface

VMware has been a famous cloud and virtualization software provider since almost two decades. The VMware virtualization suite vSphere comprises different virtualization producing including bare-metal hypervisors based on vSphere hosts (ESX/ESXi), vCenter Server, vCloud Director, VMware NSX (previously known as vCloud Networking and Security), VMware Horizon Mirage (desktop virtualization), and so on. Virtualization is based on an operating system that can be installed on bare-metal servers and work stations to host other operating systems, for example, Linux, Unix, Windows, and many more. This allows vSphere hosts to share and distribute the available resources (computation, memory, and disk drive) among different hosted virtual machines, and allows them to install different operating systems without exposing the hardware architecture.

Today, many organizations, universities, and research institutes are widely adopting virtualization for day-to-day computing needs using the VMware vSphere hypervisor. Wide growth in vSphere-based infrastructures also requires troubleshooting and resolution of different related issues of the vSphere hypervisor. This is a book that enables system engineers and data center architects to troubleshoot most of the common problems that can be faced in a data center based on the vSphere infrastructure. The book lets you develop a clear and minute troubleshooting approach and lets you adapt to it by practicing it. Real vSphere problems that system engineers may face in the data center are covered by example in this book. In addition to that, vSphere Troubleshooting can be used as a reference and provides a complete overview of the concepts and knowledge necessary for system engineers. You will learn new skills, new tools, and ready-to-use troubleshooting recipes by reading it.
