High Availability HA cluster solution for FreeBSD
HAST + CARP + ZFS
HAST (Highly Available Storage) - allows to transparently store data on two physically separated machines connected over the TCP/IP network.
CARP (Common Address Redundancy Protocol) - allows multiple hosts to share the same IP address. In some configurations, this may be used for availability or load balancing. Hosts may use separate IP addresses as well, as in the example provided here.
