DataHub High Availability & Data Source Redundancy Solutions

Flexible Functionality, Many Scenarios 

High availability and redundancy mean different things to each user.  DataHub can address many scenarios, more than we can show. We encourage contacting us to discuss your application. 

Use cases supported include but not limited to:

• High availability DataHub instances including at multiple levels by leveraging DataHub's secure real-time data tunneling functionality
• Redundant data sources, not just OPC but many different data sources including OPC DA, UA, A&E, UA A&C, MQTT and more can be treated as redundant.  

The graphic here shows a single advanced scenario.  Please request a consultation to discuss your application.

Flexible Data Source Changeover Triggers

• Supports configuration of different changeover criteria for varying data sets and sources
• Link monitoring quickly detects network breaks.
• Event-based monitoring of points or link monitoring of the connection, or use both together.
• Data Flow Detection can switch data sources when data stops changing, indicating a problem
• Switchover can trigger on changes in point value or quality, for a single point or any point in a group.

The screen here shows a sampling of the many configuration options for DataHub data source redundancy.

Data Source Redundancy Case Study

The Mukhaizna oil field in Oman started out using the DataHub for data aggregation and tunneling of data to feed data to SQL Server, OSI PI, and Iconics. 

To provide increased availability, the company has installed an additional OPC server at some locations. Working with Software Toolbox Product Support Engineers they added DataHub data source redundancy. If the quality of an indicator changes to “Bad” or “Not Connected” on the primary OPC server, the OPC DataHub immediately switches to the redundant OPC server and continues collecting data from there. 

Many Advanced & Powerful Scenarios Possible

DataHub can support a wide range of scenarios so we encourage you to talk with us before you decide DataHub can't handle your scenario.

Examples include:

• Networked redundancy
• Networked multiple-client redundancy
• Multiple redundant pairs of networks, data sources, data servers 
• High-available/redundant DataHub Instances

Licensing DataHub Data Source Redundancy & High Availability

Redundancy & High Availability can be added to any DataHub Solution Pack. You can include the feature in a new license purchase or add it on later.
