Abstract: A communicative building management system (BMS) can enable replication of data from computer systems that may potentially be affected by various external events. The BMS is coupled to environmental sensors and configured to receive sensor signals and communicate with one or more computer systems implementing a service. The BMS notifies a console system administrating a service that one or more computer systems implementing the service are affected by a data center event based on signals received from one or more sensor devices associated with a zone including the affected computer systems. A console system commands replication of data stored on the affected computer systems to separate computer systems based at least in part on the notification from the BMS indicating the computer systems are affected by the data center event.
