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.

Transparent page sharing

Transparent Page Sharing (TPS) is a memory saving technology used by vSphere that allows for duplicate memory pages to be shared between virtual machines. To address security concerns about sharing memory between virtual machines across security domains, TPS can be disabled, enabled across groups of virtual machines with the same salt settings, or enabled across all virtual machines in the environment.

How to do it...

Refer the following steps to design and implement TPS:

  1. Identify the different options for sharing duplicate memory pages within a virtual machine and across groups of virtual machines
  2. Configure TPS to meet requirements for the security and performance of the environment
  3. Configure salt...
