VMware vSphere 6.7 Data Center Design Cookbook - Third Edition

By: Mike Brown, Hersey Cartwright

Overview of this book

VMware is the industry leader in data center virtualization. The vSphere 6.x suite of products provides a robust and resilient platform to virtualize server and application workloads. This book uses proven infrastructure design principles and applies them to VMware vSphere 6.7 virtual data center design through short and focused recipes on each design aspect. The second edition of this book focused on vSphere 6.0. vSphere features released since then necessitate an updated design guide, which includes recipes for upgrading to 6.7, vCenter HA; operational improvements; cutting-edge, high-performance storage access such as RDMA and Pmem; security features such as encrypted vMotion and VM-level encryption; Proactive HA; HA Orchestrated Restart; Predictive DRS; and more. By the end of the book, you will be able to achieve enhanced compute, storage, network, and management capabilities for your virtual data center.

Enabling CPU hot add and memory hot plug

Adding CPU and memory resources to a virtual machine is a simple process. The process to add resources to a virtual machine is to power down the virtual machine, increase the number of vCPUs or the amount of memory, and power on the virtual machine again.

In vSphere 4.0, two new features, CPU hot add and memory hot plug, were introduced to allow for virtual machine vCPUs and virtual machine memory to be increased without requiring that the virtual machine be powered off. CPU hot add and memory hot plug must first be enabled on the virtual machine, which does require it to be powered off. Once it is enabled, however, CPU and memory resources may be added dynamically; powering off the virtual machine is not necessary.
