The kernel of Trionas LX HA runs the QSM (Qsan Storage Management) operating system that supports genuine active – active dual controller design with fast failover and cache mirroring. In addition to that, all system components are redundant and hot swappable to prevent any single point of failure.

With two controllers working at the same time, IOPS performance is 30% faster than just single controller mode. Vertically with JBOD expansion, it can support up to 256 hard drives or over 1PB capacity. Moreover, Trionas LX HA also supports up to 4096 file-level snapshots, which helps to provide a good protection against virus attack and accidental deletion or modification to valuable data. “Trionas LX HA is a truly active-active design that supports ALUA capability. In some cases, failover time is around 10 seconds. It gives you an insurance of mind that crucial business services will keep running without impact.“ says Daniel Lin, the sales director in Qsan.

The ALUA (Asymmetric Logic Unit Access) is supported in Trionas LX HA to provide active-active (active-dual) controller mode. Command shipping and data shipping functions are implemented in the QSM operating system. This ensures higher fault tolerance and better performance and efficiency.

As it is built with a redundant modular design, there is no single point of failure; the fully redundant and modular design is able to achieve 99.999% availability. All data services are protected by controller failover. The faster the failover is, the less impact to business continuity. Failover time is a quintessential index to judge the quality of a dual controller NAS system.

Trionas LX HA can scale vertically with capacity expansion and horizontally with performance gain. Storage tiering function (SSD caching) is supported in the QSM operating system to leverage the benefits of flash technology. Hybrid storage can combine SSD drives and enterprise SATA drives to deliver the equivalent IOPS to performance SAS hard drives. Hybrid storage can help you combine the strengths of both SSD drive and SATA drive and enjoy an overall lower cost at the same time.
