Inter-Rack Redundancy Support
Inter-Rack redundancy or Geographic redundancy support refers to the ability of a system or service to maintain its functionality and availability in the event of a failure or outage at one geographic location by shifting operations to another geographically separated location.
Note | In inter-rack redundancy support section, the concepts of "Inter-Rack" and "Geo-Redunancy" are used together, however, these are two different deployment models. The concept of site with respect to Inter-Rack is within the same DC or physical location. Inter-Rack does not support the redunancy concepts extended between two different geo-locations. For true Geo-redunancy deployment please refer to Inter-Site Geographic Redundancy section in this chapter. |
