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.
