VMware vSphere 6.x Datacenter Design Cookbook - Second Edition

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. With the release of 6.x a whole range of new features has come along such as ESXi Security enhancements, fault tolerance, high availability enhancements, and virtual volumes, thus simplifying the secure management of resources, the availability of applications, and performance enhancements of workloads deployed in the virtualized datacenter. This book provides recipes to create a virtual datacenter design using the features of vSphere 6.x by guiding you through the process of identifying the design factors and applying them to the logical and physical design process. You’ll follow steps that walk you through the design process from beginning to end, right from the discovery process to creating the conceptual design; calculating the resource requirements of the logical storage, compute, and network design; mapping the logical requirements to a physical design; security design; and finally creating the design documentation. The recipes in this book provide guidance on making design decisions to ensure the successful creation, and ultimately the successful implementation, of a VMware vSphere 6.x virtual data center design.

Enabling CPU Hot Add and Memory Hot Plug


Adding CPU and memory resources to a virtual machine is a simple process. The process of adding 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 virtual machine vCPUs and the virtual machine memory to be increased without requiring the virtual machine to be powered off. CPU Hot Add and Memory Hot Plug must first be enabled on the virtual machine, which requires it to be powered off. Once enabled, however, CPU and memory resources may be added dynamically; powering off the virtual machine is not necessary.

How to do it…

Perform the following steps to enable vCPU Hot Add and Memory Hot Plug for virtual machines:
