Hello I'm using ProxMox as virtualization, from verson 2.x. For around 20 servers (most of them are Centos machines) for different services (Zimbra, Apache, MariaDB, PostgreSQL, EDB, ..) and also for MS servers (AD, Exchange, fileserver, MSSql Express, .). They all are running on 5-6 HW servers

How many extra servers can you add to your setup? If I were in your shoes, I would consider building a file server/NAS with fast connection to your server(s). Then share the data to your services to the server (NFS?), export the disk (iscsi) or some combination of both. I hope someone can correct m

If OpenGL is a big concern, then virtualization is an ok option, but not a very good one. Despite some OpenGL/DirectX support in VM's, with the apps mentioned, bare metal may be the best choice. However, experiment and see if your particular apps will work good enough for you. We use Maya,
