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.

Scaling up or scaling out


Once the total CPU and memory resource requirements have been calculated, the amount of resources per host must be determined. Host resources can be designed based on two resource-scaling methodologies, scaling up or scaling out.

When scaling up, fewer, larger hosts are used to satisfy the resource requirements. More virtual machines run on a single host; because of this, more virtual machines are affected by a host failure.

When scaling out, many smaller hosts are used to satisfy the resource requirements. Fewer virtual machines run on a single host, and fewer virtual machines will be affected by a host failure.

How to do it…

  1. Determine whether the host in the environment should scale up or scale out.

  2. Determine the number of virtual machine workloads per host.

  3. Based on the number of virtual machines per host, calculate the number of hosts required. This should also include the number of hosts required to support growth and failover:

    (Number of Workloads / Number of Workloads...
