Mixed configuration of
Local HA and Remote DR
Core Lab Cluster provides functions that enable management by
integrating local HA and remote DR.
Local mirroring is used to respond to routine failures, and remote data
replication is used to prepare additional data copies in case the main
center loses functionality.
Local downtime is usually less than 1 minute, and DR recovery is
expected to be within 4 hours.
Monitoring and control are provided by the Core Lab Cluster through
an integrated console.
