Product Description

QSAN U400HA-D424 RJ45 TrioNAS LX HA iSCSI 24 Bay 4U NAS

Dual controller NAS for your mission-critical enterprise storage

99.999% availability, genuine active-active dual controller NAS with responsive failover time


  • Cache mirroring through high speed bus (64Gb/s) on backplane board
  • 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 & fault tolerance design

No single point of failure. RAID controller, fan module, and power supply module are redundant and hot swappable for maximum availability and super 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.

Fast failover

Why do you want dual controller NAS? It’s because you need an insurance that when one of NAS controllers fails, the data services get the lowest impact, which means the failover time is as short as possible. So the users and applications won’t even notice that one of NAS controllers is down. Beacuse heartbeat signal and inter-process communication data are carried out through cable-less, high-speed bus on backplane board, U400HA and U600HA can deliver very responsive failover to keep your mission-critical applications running smoothly. Failover time in TrioNAS LX HA is less than 60 seconds on average. In some cases, it is around 10 seconds. All data services (SMB, NFS, iSCSI) are protected by controller failover.

Unified storage and file sharing center 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. SMB, NFS, and iSCSI protocols are supported with fault tolerance capability. TrioNAS LX HA can act as your file sharing center for Windows clients and Linux/Unix clients to exchange files easily. 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.

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.

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.

Hybrid storage for flexibility and performance

All Qsan NAS product lines can leverage the strengths of SSD drives to become a so-called Hybrid Storage. With SSD caching function, SSD drives act as a fast tier between traditional hard drives and memory to speed up random IO performance.

Fail-safe networking

File-sharing services (SMB and NFS) are provided through cluster IP, which is composed of mirrored network ports from both RAID controllers. So each cluster IP contains dual network paths, one from each RAID controller. Should any network component (port of network switch, cable, network port on RAID controller) along the path fails, the network packets will be quickly switched to the redundant path. The transition is transparent. SMB and NFS file access can continue as if nothing happens at all.

Scaled performance

Becasue of active-active design, both RAID controllers can provide data services and deliver I/O at the same time. By adding a second controller, dual controller mode is actually 30%~50% faster than its single controller mode in terms of IOPS for small I/O size. Not only do you buy the high availability and insurance plan for data services and your precious data, but you get scaled performance as well.

3x times storage efficiency

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-based deduplication helps you remove data redundancy at block level. It's a must-have feature for file backup, data archive, VDI and mail databese applications. It's very easy to use and can be switched on/off at any time without impacting data access. It's a practical function only found in enterprise storage.

Compression can help save even more storage space. It's lossless and there is no data loss at all. All these great features come in totally FREE and can help boost your storage efficiency by 3x times!!

*Deduplication will be supported in the near future without extra license cost.

File-level 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.

Block-level 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 LX HA supports block-level snapshot-based replication function. It is asynchronous. Remote replication task can be created for folders and LUNs. Only differential data at block level will be replicated to achieve maximum efficiency. Replication function is provided by storage array itself. No host server resources are involved and host servers can remain focusing on mission-critical applications.

When disaster strikes at site A, you can quickly switch to storage array at site B to make sure business continuity and data security.
