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.

Right-sizing virtual machines

Right-sizing a virtual machine means allocating the correct amount of CPU, memory, and storage resources that are required to support a virtual machine's workload. The optimal performance of the virtual machine and the efficient use of the underlying hardware are both obtained through right-sizing virtual machine resources.

In a physical server environment, it can be difficult and time-consuming to add resources:

  1. Compatible parts will need to be identified
  2. The parts will need to be ordered
  3. You will likely need to wait weeks for the parts to arrive
  4. Someone will need to be in the data center
  5. The server will need to be shut down
  6. The server will need to be removed from the rack and opened up
  7. The parts need to be installed

Because of this, physical servers are often configured with more resources than are actually required to ensure that there are...
