Qsan for years has won many proven records in enterprise market and now TrioNAS LX HA series provides the most cost-effective dual controller solution for enterprise NAS market. TrioNAS LX HA can help you scale capacity, performance, and service availability at the same time and provide zero business downtime in one box.

A breed apart : Dual controller NAS
Image that two cluster nodes are placed in one box with high speed bus connected with each other. This is how TrioNAS LX HAS is designed. The memory caches of both controllers are in mirror all the time using high speed PCI-Express lanes implemented on the backplane, not the cable solution you may see in most cluster environment using commodity server hardware. This is why TrioNAS LX HA has responsive failover time and better performance and efficiency. Moreover TrioNAS LX HA offers a lower total cost solution and flexibility to scale capacity and performance at the same time.
Cache mirroring through high speed bus, not cable solution
Active-active design and support ALUA
Responsive failover time
Easy management to scale performance and capacity
No quorum disk is needed.
More economic than commodity cluster servers

Redundant modular design
RAID controller, fan module, and power supply module are all redundant and hot swappable for maximum availability and easy on-site maintenance. All modules are connected to the backplane circuit board to achieve the most reliable signal transmission and the best aerodynamic thermal efficiency.

ALUA support
ALUA (Asymmetric Logic Unit Access) is supported in TrioNAS LX HA to provide active-active controller mode. Command shipping and data shipping functions are implemented by Qsan in-house technology. This enables higher fault tolerance and better performance and efficiency.

Unified storage with simple management
TrioNAS LX HA consolidates NAS and IP-based iSCSI SAN in one box. Unified storage can help consolidate your IT infrastructure and reduce hardware expenses. You don't need multiple file servers for SMB, NFS, AFP and FTP*. TrioNAS supports all these protocols in one box including iSCSI. TrioNAS LX HA will be your common storage pool that is accessible at either file or block level over existing IP networks. It's the most cost-effective and efficient storage solution.
*AFP and FTP will be supported in the near future.

ZFS and RAID protection
TrioNAS LX HA adopts ZFS file system, which is a transactional, copy-on-write, crash-free file system with 128-bit huge addressing space. ZFS can detect silent data corruption and has self-healing capability and guarantees end-to-end data integrity. There are abundant RAID levels* to choose from to meet application requirements such as redundancy and performance.

SOE & ZVIOS to boost performance
SOE (Samba Offload Engine) and ZVIOS (ZFS Volume IO Scheduler) are Qsan in-house technologies. SOE can greatly improves SMB (Small Message Block) protocol performance. ZVIOS can accelerate block IO such as iSCSI protocol performance.

SSD caching support
TrioNAS LX HA supports using high performance SSD drives as fast storage tiering. SSD caching* can greatly improve random IO performance. You can combine SSD drives and SATA drives as a hybrid storage pool and have a net performance result of a pure SAS storage pool.

Thin provisioning and deduplication
Thin provisioning allows just-in-time capacity and allocates storage space that does not exist. You can delay the hard drive purchase until it is absolutely necessary.
Inline block-level deduplication* provides more efficient way to remove data redundancy and save storage space. For backup and VM application, it can save up to 95% space.

Best Integration of Windows Active Directory
TrioNAS LX HA delivers outstanding integration of Windows Active Directory & LDAP for IT administrators to easily manage accounts. The supports for multiple domains of Windows Active Directory plus the patent-pending UnifiedAUTH empower TrioNAS to provide superior manageability.

Folder and share snapshot
File-level snapshot helps IT administrator to retrieve a file as easy as browsing through a directory when things like virus attack and accidental deletion or modification happens. You can rollback the snapshot to a certain point in time in the past or clone the snapshot to become an independent folder.

LUN snapshot
TrioNAS LX HA supports snapshot for block-level storage such as LUN. Using copy-on-write technology, differential data are recorded between two given points in time. You can rollback the snapshot to a certain point in time in the past or clone the snapshot to become an independent LUN.

Remote replication for disaster recovery
TrioNAS supports both Rsync and block-level snapshot-based replication function. Both of them are asynchronous. Remote replication task can be created for folders and LUNs. Only differential data at block level will be replicated to achieve maximum efficiency.
When disaster strikes at site A, you can quickly switch to site B to make sure business continuity and data security.

Features
TrioNAS LX HA adopts dual controller and fault tolerance design. Both controllers can deliver data services at the same time. It's a genuine active-active design.
RAID controller, fan module, and power supply are all redundant and hot swappable to achieve no single point of failure design.
Network port failover can immediately carry on data services through the mirrored port on peer controller.
Controller failover and online firmware upgrade can provide non-stop data services to protect your valuable data.
Controller failback can be set as manual for flexible management.
