Customer Provisioning System to SDS Overview

Each SDS server has identical software. Two of the applications that exist on each SDS server are the XML Data server and the SOAP server. These applications run within the same process named XDS.

The customer's provisioning system must be configured so it can have SOAP and/or XML connections to the Primary and Disaster Recovery (DR) Provisioning sites by using the Virtual IP (VIP) address for each site. The SOAP and/or XML ports are also configurable.

The customer's provisioning system only establishes active connections to the active site (usually the Primary Provisioning Site). In the event of a failure of the active SDS server, the Standby SDS server is activated, and the VIP is moved over to that server.

In the event of a failure of the Primary Provisioning Site, the DR Site becomes active. The Client Provisioning Systems must manually switchover from the Primary SDS VIP to the DR SDS VIP.
