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.

Introduction


This chapter covers logical compute design. Compute refers to the processor and memory resources required to support the virtual machines running in the vSphere environment. Calculating the required CPU and memory resources is an important part of the design process and ensures that the environment will be able to support the virtual machine workloads. Design decisions, such as scaling up, scaling out, and clustering hosts, are covered as well. The following diagram displays how the compute design is integrated into the design process:

In a physical environment where a single operating system or a single application is installed on a dedicated physical hardware, compute utilization usually averages 10-20 percent of the available resources. A majority of the memory and CPU resources are idle and wasted. In a virtual environment, the resources available are utilized by multiple operating systems and applications. It is not uncommon to see a usage of 65-80% of the available resources...
