Bonjour,
voici une information (pour Exch2010 mais qui s'applique aussi à Exch2013) provenant d'un membre de l'équipe produit:
Mixing physical and virtual servers in a DAG is possible and supported. The physical server and virtual server in this case do not need to be identical (not CPU, disk, RAM, etc.).
What you must keep in mind is that if there is a failure scenario of some sort, the virtual machine must be engineered to support the load expected of it. In other words, if you have a two-node DAG with one physical and one virtual, and the physical server
requires 16 cores, then the virtual machine which is limited to 4 or possibly 8 cores will probably not support the necessary load in a failure scenario.
