VMware vSphere 6.x Datacenter Design Cookbook - Second Edition

By: Hersey Cartwright, kim bottu

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.

Calculating CPU resource requirements


There are several factors that must be considered when calculating CPU resources' requirements, such as the amount of CPU resources required to support the current workloads, the amount of CPU resources required to support future growth, and the maximum CPU utilization threshold.

The following discovery information from Chapter 3, The Design Factors, will be used to calculate the CPU requirements:

  • Currently, there are 100 physical servers, each hosting a single application. Each application services 10 customers.

  • The business expects to add 50 new customers over the next year.

  • Support growth over the next 5 years.

  • Each application server is configured with two dual core 2.7 GHz processors. The peak usage of a single application server is approximately 10% of the total or approximately 1 GHz.

How to do it…

  1. Determine the amount of CPU resources required to support the current workloads:

    Number of Workloads x CPU Speed in MHz or GHz = Current CPU Resources Required...
