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.

Using Distributed Resource Scheduling to balance cluster resources


The vSphere DRS determines the initial placement and balances resources across available host resources in a vSphere cluster. Virtual machine resources can be guaranteed or limited. Rules can be applied to keep virtual machines together on the same host or to ensure that virtual machines run on separate hosts.

How to do it…

  1. Edit the settings of the vSphere cluster to enable vSphere DRS.

  2. Select a value for the DRS Automation level that should be applied to the DRS-enabled cluster.

  3. Select a value for Migration Threshold that should be applied to the DRS-enabled cluster.

How it works…

vSphere DRS can be enabled when creating a new vSphere cluster or by editing the settings of an existing cluster:

When DRS is enabled, the DRS Automation Level and Migration Threshold value is set to determine how DRS will place and migrate virtual machines between hosts in the cluster in order to balance the resources across all hosts in the cluster...
