On each server, the following roles need to be installed:

• Failover clustering
• Hyper-V
• File Server (if you want to host any file shares, such as for a converged deployment)
• Data-Center-Bridging (if you're using RoCEv2 instead of iWARP network adapters)
• RSAT-Clustering-PowerShell
• Hyper-V-PowerShell

 You can do this using Server Manager or the following PowerShell command:

Install-WindowsFeature -Name "Hyper-V", "Failover-Clustering", "Data-Center-Bridging", "RSAT-Clustering-PowerShell", "Hyper-V-PowerShell", "FS-FileServer" -IncludeAllSubFeature -IncludeManagementTools
