VMware vSphere 6.7 Data Center Design Cookbook - Third Edition

By: Mike Brown, Hersey Cartwright

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. This book uses proven infrastructure design principles and applies them to VMware vSphere 6.7 virtual data center design through short and focused recipes on each design aspect. The second edition of this book focused on vSphere 6.0. vSphere features released since then necessitate an updated design guide, which includes recipes for upgrading to 6.7, vCenter HA; operational improvements; cutting-edge, high-performance storage access such as RDMA and Pmem; security features such as encrypted vMotion and VM-level encryption; Proactive HA; HA Orchestrated Restart; Predictive DRS; and more. By the end of the book, you will be able to achieve enhanced compute, storage, network, and management capabilities for your virtual data center.

Reserving HA resources to support failover

When vSphere High Availability (HA) has been enabled on a vSphere cluster, the virtual machines running on the cluster are protected from a host hardware failure or virtual machine guest operating system crash.

In the event that a host suffers a hardware failure, or if ESXi crashes, the virtual machines are restarted on the surviving hosts in the cluster. Resources must be reserved in the cluster to guarantee that the necessary resources are available to restart the virtual machines.

How to do it...

Refer the following steps to reserve HA resources to support failover:

  1. Edit the settings of the vSphere cluster to enable high availability
  2. Enable the HA Admission Control policy
  3. Select...
