Bring enterprise-class features to SMBs

Cost-effective, affordable, entry-level unified NAS for SMB

  • VMware Ready LOGO

Centralized data archive with simple management

TrioNAS 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, FTP, and WebDAV. TrioNAS supports all these protocols in one box including iSCSI. TrioNAS 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.
Redundant power supply for better availability

TrioNAS U120 has equipped with redundant power supply modules to increase its availability. It's rare to see such combination in 1U form factor.
ZFS and RAID protection

TrioNAS 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.

*U120 only supports RAID 0, 1, 5, 10.
Q-Turbo offload engines

Q-turbo offload engine includes both SOE (Samba Offload Engine) and ZVIOS (ZFS Volume IO Scheduler) modules, two QSAN innovated in-house IO acceleration technologies. SOE can greatly improves SMB (Small Message Block) protocol performance. ZVIOS can accelerate block IO such as iSCSI protocol performance.
UnifiedAUTH for unified authentication

Imagine the working environment with Windows server, Unix server, FTP server, and iSCSI target storage. You probably will need AD account for CIFS service, Unix account for NFS service, FTP account for FTP service, and iSCSI CHAP account for iSCSI target storage. Try to memorize all these accounts and passwords every day. UnifiedAUTH releases you from this shackle by using the same account authentication for all data services including iSCSI target! You only need to remember ONE password!!
SSD caching support

TrioNAS 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.

*U120 does not support SSD caching function.
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.
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!
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 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.  Replication function is provided by storage array. 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.
McAfee anti-virus to safeguard your files

NAS is a centralized data TrioNAS integrates McAfee's latest API to support virus scanning function, which makes TrioNAS one of the most secure NAS on the market. The benefits are :
  • Daily updates for the latest virus pattern from McAfee.
  • Astounding 99% of computer viruses can be detected by McAfee, which provides 360o protection.
  • Scanning file size up to 8GB, the highest spec in the industry
  • Support scheduled tasks to avoid rush-hour traffic
