Powered by an Intel® Xeon® D processor, the powerful enterprise-class TES-3085U is open for two operating systems – either the FreeBSD-based QES or Linux-based QTS. While QES supports ZFS for the utmost reliability and allows near-limitless snapshots, block-level data deduplication and real-time data compression, QTS features Qtier Technology, SSD cache, and an abundance of value-added apps to realize storage efficiency and diverse usage applications. The TES-3085U gives the flexibility to choose from two operating systems, enabling businesses to deploy proper operating systems on multiple TES-3085U based on their needs and goals in different stages. The TES-3085U is especially useful for providing a speedy all-flash storage solution that offers up to 24 disk bays and 6 dedicated SSDs bays for caching.
Note: To change the NAS operating system after completing setup, it is necessary to re-initialize the hard disks and delete all stored data. A remote backup is required before switching the NAS operating system.

QES operating system based on FreeBSD & ZFS
The TES-3085U supports the brand-new QES (QNAP Enterprise Storage) operating system, which is based on the simple and efficient FreeBSD kernel and the ZFS file system that has been proven through years of experience to be most suitable for high-end enterprise applications. Continuing the same user experience with the QTS operating system, QES provides business users with an easy learning curve to quickly deploy the TES-3085U, and provides the best storage solution jointly with the current QNAP NAS.
Note: TES-3085U requires at least 32GB RAM to run QES operating system.
ZFS – the best file system for business data storage
The TES-3085U features ZFS, a combined file system and logical volume manager, to support various advanced functions for high-end enterprise storage, including powerful storage expansion, flexible storage pools, RAID-Z for data protection, simplified management, high-performance SSD cache, nearly limitless snapshots and cloning, data deduplication, in-line compression, self-healing, and thin provisioning with reclaim for optimized utilization for virtual machine storage. ZFS is designed with a focus on data integrity, and uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors, effectively protecting user’s data.
Deduplication and compression to maximize VDI storage performance
All-flash storage featuring high-performance random I/O is advantageous for databases, online transaction processing (OLTP), and virtual desktop infrastructure (VDI) applications. Though the cost of all-flash storage is higher than using normal hard drives, data deduplication and compression technology can greatly assist in storing more data in less storage space with greater cost-efficiency and performance gains. Using VDI for example, there could be over 90% duplicate data from OS images and applications that are spread over virtual desktops. The TES-3085U supports block-based data deduplication to optimize storage usage from redundant data. Deduplicated virtual desktops become easier to be cached to achieve optimal virtual desktop performance. In-line data compression helps shrink data size, further optimizing storage usage. For mastering storage in a virtualized environment, the TES-3085U provides businesses with the most cost-effective remote virtual desktop platform and mission-critical information warehousing.
Strong disaster recovery made by nearly limitless snapshots and SnapSync
The TES-3085U supports up to 65,536 snapshots for iSCSI LUN and shared folders. When executing a remote snapshot backup, it only needs to transfer changed data, and can use deduplication and compression to significantly reduce the amount of transferred data. The TES-3085U can provide remote backup SnapSync for snapshots at the shortest interval of every five minutes, fully supports VMware vCenter Site Recovery (SRM) technology, provides Storage Replication Adapter (SRA) for SRM, and provides enterprise-class remote backup & disaster recovery solution to fulfill business continuity.
Well-rounded backup solutions to secure data
QNAP NetBak Replicator is easy-to-use and VSS-aware backup software, and helps businesses to create complete backups in datacenter and virtualization environments without needing to purchase expensive and complex commercial software. To build a QNAP Snap Agent and VSS Hardware Provider operating environment, all applications (including VSS Service, Requestor, Provider and QNAP Snap Agent) can be deployed with VSS-Aware applications on the same server, and the minimal requirements are only one TES-3085U and one server for it to be operational.
Storage for comprehensive virtualization applications
The TES-3085U supports VMware® vSphere™ 6.0 and Citrix® XenServer™ 6.0, and is compatible with Microsoft® Hyper-V®, benefiting flexible deployment and management in virtualization environments. The TES-3085U supports VMware VAAI and Microsoft ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively, and supports QNAP vSphere Client plug-in, Web plug-in and QNAP SMI-S provider with enhanced efficiency of operations and management in virtualization applications.

Ideal backup NAS for Enterprise ZFS NAS
When running the QES operating system, the TES-3085U is the perfect backup storage for the dual-controller Enterprise ZFS NAS using SnapSync. If the Enterprise ZFS NAS unexpectedly stops, the TES-3085U can immediately recover all the backed up data locally to take over operations and services with maximized uptime. It prevents the downtime required to restore data from a remote QTS NAS/rsync server back to the recovered Enterprise ZFS NAS, making the TES-3085U the best option to pair with the Enterprise ZFS NAS as a backup NAS to achieve optimal recovery time objectives.
|Backup destination||Enterprise ZFS NAS or TES NAS||QNAP NAS (QTS OS)||rsync Server|
|Backup method||QNAP SnapSync||rsync||rsync|
|iSCSI LUN backup||Yes||Yes||No|
|VMware Site Recovery Manager||Yes||No||No|
App-centric Linux-based QTS operating system
The QTS operating system not only supports storage optimization with Qtier for driving auto-tiering, block-based snapshot, and SSD read/write cache, but also provides rich business-ready applications and functionality, providing a comprehensive all-in-one NAS solution.
Tiered storage and application-based partitioning
QNAP's Qtier Technology empowers the TES-3085U with Auto Tiering that helps continuously optimize storage efficiency across SSDs and SAS/SATA drives. With Auto Tiering, the TES-3085U can automatically move frequently-used "hot" data to high-performance storage tiers and less-accessed "cold" data to lower-cost, higher-capacity drives, making the TES-3085U an extremely efficient shared resource. SSDs and SAS/SATA drives can also be configured as independent partitions for different applications, ensuring a sufficient throughput level for every application.

Cross-platform file sharing, centralized data storage
The TES-3085U supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows®, Mac®, and Linux®/UNIX® networks. Data, logs and ISO images of CDs and DVDs can be centrally stored on the TES-3085U and protected by an integrated antivirus solution. The Windows AD® and LDAP services enable system administrators to configure user permissions by using existing Windows AD server, LDAP server or NAS build-in LDAP services. The TES-3085U supports SAMBA v4 and can act as a domain controller for Windows®.
Well-rounded backup & disaster recovery solutions
The TES-3085U offers flexible backup solutions for Windows® and Mac® users, Volume/LUN snapshots, Snapshot Replica and Clone, and disaster recovery solutions including RTRR, rsync and cloud storage backup (Amazon® Glacier, Azure™ Storage, Google Cloud Storage™, Google Drive™, Microsoft® OneDrive, Dropbox®, Amazon® Drive, Yandex® Disk, Box®, and Amazon® S3/OpenStack Swift/WebDAV compatible cloud services) are also included.
Volume & LUN snapshot simplifies restoration
QTS Storage Manager features an easy-to-use web-based snapshot tool for you to easily back up and restore data on the TES-3085U back to any point of time to prevent losing important data. You can take snapshots for both volumes and LUN (block-based LUN* and file-based LUN), efficiently replicate volume/LUN snapshots to remote servers by only copying the changes made, and quickly clone a volume/LUN snapshot as a local volume without interrupting current system operations. You can even set up the system to automatically take a snapshot of the volume before backup via RTRR/rsync, even when files are open.
* Up to 256 snapshots per volume or LUN, and a maximum 1,024 snapshots per NAS. It is recommended to use block-based LUN snapshots.
