10/08/2015 -  With its most recent firmware (2.05.12) update, Thecus has added its System Failover feature to ThecusOS 5.0. By utilizing System Failover, users will be able to create data, network, and system redundancy, minimizing disruptions in workflow and increasing operational efficiency.

The Thecus System Failover feature is a fault tolerance process that creates mirrored data volumes.  With at least two Thecus NAS available, data is copied by schedule and all changes are mirrored between the two NAS. While the second NAS is not visible, it communicates with the primary NAS. In the event of a power or network failure, a scheduled maintenance, or other unforeseen circumstances, System Failover automatically redirects operations to the secondary Thecus NAS, which then acts as the primary NAS.

With System Failover, ThecusOS 5.0 users are given an enterprise-class feature accessible by both small and large businesses that brings with it tremendous value at a fraction of the cost of similar solutions in the industry.

System Failover is available for the following Thecus NAS models:

·  N16000, N12000, N16000PRO, N12000PRO, N16000V, N12000V, N8900V, N8900PRO, N8900
·  N6850, N8850, N10850
·  N7710, N7710-G, N7770-10G, N8810U, N8810U-G, N8880U-10G, N7700PROV2, N8800PROV2
·  N2800, N4510U, N4510UPRO, N4800, N4800ECO, N5550, N5810PRO, N7510
