Failover cluster prerequirements
To successfully implement a Hyper-V Failover Cluster, we need suitable hardware, software, permissions, and network and storage infrastructure as outlined in the following sections.
Hardware requirements
The hardware used in a Failover Cluster environment needs to be validated against the Windows Server Catalog, as we did in Chapter 1, Accelerating Hyper-V Deployment. Microsoft will only support Hyper-V clusters when all components are certified for Windows Server 2016.
The servers used to run our HA virtual machines should ideally consist of identical hardware models with identical components. It is possible, and supported, to run servers in the same cluster with different hardware components, that is, with different sizes of RAM; however, due to a higher level of complexity, this is not the best practice.
Special planning considerations are needed to address the CPU requirements of a cluster. To ensure maximum compatibility, all CPUs in a cluster should be...
