Disaster Recovery

Situation

Industrial and telecommunications applications are required to have high availabilty and uptime. However, like all computer based systems they are open to complete or partial failure. Problems can range from minor issues such as virus attacks, software issues, and hardware failures to serious catastrophes such as power failures, fires, and floods.

Solution

Loop’s major network management software, Loop-iNMS, comes with an optional feature called Disaster Recovery. In this solution, two suites of iNMS servers are installed at different geographics sites. One is designated as the Primary Site and the other as the Secondary Site.

If a catastrophe strikes at the Primary Site, you will still have data integrity and can manually switch to the Secondary site as soon as possible. Manual switching (instead of automatic switching) allows for human-based judgement on whether an event is major or minor. After the disaster has passed, the secondary site can remain the primary, running instance or you can switch back to the first site as the running instance.

Above and Beyond

Loop-iNMS Disaster Recovery allows for rapid resumption of iNMS applications and bringing up iNMS databases back online with minimal data loss. It supports asymmetric architecture of component and server deployment and non-stop access to iNMS applications during the database synchronization period. Furthermore, delta-synchronization mode reduces network overhead during synchronization.
