Proxmox HA Cluster

We are living in a world where email becomes more and more important - failures in email systems are just not acceptable. To meet these requirements we developed the Proxmox HA (High Availability) Cluster.

The Proxmox HA Cluster consists of a master and several nodes (minimum one node). Configuration is done on the master. Configuration and data is synchronized to all cluster nodes over a VPN tunnel. This provides the following advantages:

• centralized configuration management
• fully redundant data storage
• high availability
• high performance

We use a unique application level clustering scheme, which provides extremely good performance. Special considerations where taken to make management as easy as possible. Complete Cluster setup is done within minutes, and nodes automatically reintegrate after temporary failures without any operator interaction.
