Overview of this book

vSphere 6.7 is the latest release of VMware's industry-leading virtual cloud platform. By understanding how to manage, secure, and scale apps with vSphere 6.7, you can easily run even the most demanding of workloads. This Learning Path begins with an overview of the features of the vSphere 6.7 suite. You'll learn how to plan and design a virtual infrastructure. You'll also gain insights into best practices to efficiently configure, manage, and secure apps. Next, you'll pick up on how to enhance your infrastructure with high-performance storage access, such as remote direct memory access (RDMA) and Persistent memory. The book will even guide you in securing your network with security features, such as encrypted vMotion and VM-level encryption. Finally, by learning how to apply Proactive High Availability and Predictive Distributed Resource Scheduler (DRS), you'll be able to achieve enhanced computing, storage, network, and management capabilities for your virtual data center. By the end of this Learning Path, you'll be able to build your own VMware vSphere lab that can run high workloads. This Learning Path includes content from the following Packt products: VMware vSphere 6.7 Data Center Design Cookbook - Third Edition by Mike Brown and Hersey Cartwright Mastering VMware vSphere 6.7 - Second Edition by Martin Gavanda, Andrea Mauro, Karel Novak, and Paolo Valsecchi

Planning vCenter HA to increase vCenter availability

VCHA is a feature that uses a three-node cluster to protect the vCenter Server from hardware, operating system, or application failures. The three nodes are referred to as active, passive, and witness. VCHA only supports VCSA deployments, not vCenter on Windows, and both embedded and external PSCs are supported. It's important to note that if used with external PSCs, VCHA is not protecting the PSCsonly the vCenter Server itself. Load balanced PSCs would be needed to provide high availability to external PSCs. Keep in mind that it likely doesn't make sense to use vCenter HA if you're not also using load-balanced PSCs, since the idea is to create a highly available management plane.

VCHA is useful when you want to increase vCenter's uptime and you don't necessarily want to only rely on vSphere...
