Data Historian Redundancy Service
 

eDNA Redundancy

eDNA Redundancy replicates all real-time services within the eDNA product suite, providing fault-tolerant 24x7 data collection, storage, analysis, and access. This redundancy service is native to the core architecture of eDNA, eliminating expensive and complex third-party redundancy services and limited hardware solutions.


Replication


Replication involves the primary services collecting data from disparate sources and feeding this data into the secondary services.  This process synchronizes the real-time services, which then push the data into their respective histories.

In the event that the primary shuts down, the secondary will already contain the same data, with the switch-over to the secondary server transparent to the user.

Fault-Tolerance

Fault-Tolerance allows seamless fail-over between live systems. Upon failure of the primary services, the secondary establishes communication with the data sources and responds to data requests. The secondary will continue collecting, analyzing, and storing data until the primary real-time services are back online.

Practical Use

In the constantly changing world of technology, industries must regularly upgrade their systems to stay competitive. Within the utilities industry, the downtime necessary for an upgrade is inefficient and costly. eDNA Redundancy eliminates this downtime. While you are upgrading your primary system, the secondary services will continue evaluating your enterprise, ensuring your processes are cost-efficient and safe. With this service, your interface is always available for data collection and analysis and regulatory requirements are continually monitored.
