Hello, Currently we have the following configuration and would like to be "better fault tolerant" : VMs (all services are in separated VMs) : 2 NS (mirroring), 1 Mail Server, 1 Web Server, 1 MySQL ISPConfig Master is stored on Web We would like to be better fault-tolerant. Should we build another Proxmox Host ? We can redirect VMs IP to another host without a lot of problem. Bandwidth is currently limited to 500 Mbit/s between host. No limitation on the VMs. We don't care so much to have not websites up for 5-10 minutes Thank you very much for your useful advises!
