By: Romain Serre, Benedict Berger

Overview of this book

Hyper-V Server and Windows Server 2016 with Hyper-V provide best-in-class virtualization capabilities. Hyper-V is a Windows-based, very cost-effective virtualization solution with easy-to-use and well-known administrative consoles. This book will assist you in designing, implementing, and managing highly effective and highly available Hyper-V infrastructures. With an example-oriented approach, this book covers all the different tips and suggestions to configure Hyper-V and provides readers with real-world proven solutions. This book begins by deploying single clusters of High Availability Hyper-V systems including the new Nano Server. This is followed by steps to configure the Hyper-V infrastructure components such as storage and network. It also touches on necessary processes such as backup and disaster recovery for optimal configuration. The book does not only show you what to do and how to plan the different scenarios, but it also provides in-depth configuration options. These scalable and automated configurations are then optimized via performance tuning and central management ensuring your applications are always the best they can be.

Preface

Rolling cluster upgrade


Since Windows Server 2016, there is a new way to migrate a Windows Server 2012 R2 cluster to Windows Server 2016. This is called Rolling cluster upgrade. Now you can mix in the same cluster nodes running on Windows Server 2012 R2 and Windows Server 2016.

Microsoft has implemented a cluster functional level. A cluster running on Windows Server 2012 R2 is at cluster version 8 while a cluster running on Server 2016 is at cluster version 9. When a cluster contains Windows Server 2012 R2 and Windows Server 2016 nodes, it is in mixed OS mode but still in cluster version 8.

To upgrade the cluster, you have to evict each node one by one. When a node is evicted, you have to upgrade the node to Windows Server 2016 (I recommend that you do a clean install). Once the node is in Windows Server 2016, you can add it again to the cluster:

Rolling Cluster Upgrade

Once all cluster nodes are upgraded to Windows Server 2016, you can run this PowerShell cmdlet:
