Without automation software, replication technologies do not act on disaster situations to achieve recovery. GDDR has built in intelligence to “look out for” other GDDR systems: constantly checking for disaster situations and constantly ensuring that other GDDR systems are “healthy”. This constant checking allows GDDR to recognize and act on potential disaster situations, even if only one GDDR system survives.
