SEAPATH allows redundancy of hypervisors based on third parties open-source technologies.

This allows you :

  • Detect a hypervisor failure (ex: power shutdown, Network loss) within the cluster

  • Move services to another hypervisor of the cluster

  • Replicate data within the cluster

  • Resource management: communication between the different machines within a group is managed by Pacemaker and two of its plugins. Corosync is used for the intercluster communication and the Heartbeat mechanism while STONITH implements the fencing system.

  • Distributed storage: All data written to disks is replicated and synchronised within the group members by using the CEPH tool. Note that from a user point of view only a single instance of each VM can be started on the system at the same time.

  • Intelligent network: The different machines on the cluster are connected on the layer level (OSI model) using OpenVSwitch and DPDK for its administration and management.
