4.1 Introduction to SDS

The SDS/DP system consists of a Primary Provisioning Site, a Disaster Recovery (DR) Provisioning Site, and up to 32 Signaling Site servers with redundant DP SOAM servers and up to 10 DP servers in each site. Each Provisioning Site has an active/standby pair of servers in a high availability (HA) configuration and an optional third server configured as a Query server.

The SDS/DP system is built upon the EAGLE XG Platform. This platform provides a variety of services such as site-based GUI, HA capabilities (active/standby switchover and DR switchover), and database functionality (replication, backup, restore).

Every server within the SDS/DP system collects measurements, alarms, and events data. Every server has the ability to send traps directly to the customer’s SNMP Manager and can collect measurement data. This measurement data is merged up in reverse direction of replication. The DP measurements are sent to the Active DP SOAM server, which sends the measurements from all DP servers and itself to the Primary Provisioning Site’s Active SDS.

This introduction will familiarize you with the basic operation, features, and components of SDS.
