Disaster Recovery Provisioning Site

The Disaster Recovery (DR) Provisioning Site is an SDS Provisioning Site. Configuring a DR Provisioning Site is optional. If the site is configured, then a geo-diverse DR Provisioning site is recommended.

The DR Provisioning Site has the same hardware configuration and network accessibility as the Primary Provisioning Site. The Primary and DR Provisioning Sites have different VIP addresses for their active SDS servers.

The active SDS server on the DR Provisioning Site accepts updates from the Active SDS server on the Primary Provisioning Site. The DR Provisioning Site does not have an active SOAP or XML connection opened. This connection can be established when the DR Provisioning Site is promoted to be the Primary Provisioning Site.

DR Provisioning Site databases are kept current through real-time replication of subscriber and application data from the active SDS server on the Primary Provisioning Site. Under normal operating conditions, the active SDS server on the DR Provisioning Site does not provision any downstream systems. If this server is made Active, then the server takes over all functions of the active SDS server on the Primary Provisioning site, including the provisioning interfaces and database replication to subtending SOAMs. If the active and Standby SDS servers on the Primary Provisioning Site fail, then the customer must manually force a switchover to the active SDS server on the DR Provisioning Site.
