Product Description

QNAP TES-3085U-D1548-64G 30 Bay Rack Enclosure with 64GB RAM (4x16GB)

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 SDDs bays for caching.


Intel Xeon D processor optimizes performance and efficiency

Powered by an advanced 14nm Intel Xeon D-1548 8-core 2.0GHz 64-bit SoC processor with an integrated PCH, up to 128GB DDR4 ECC RDIMM RAM / 64GB DDR4 non-ECC UDIMM RAM, and with two built-in 10GbE SFP+ ports, the 12Gb/s SAS-enabled TES-3085U delivers outstanding performance for data transmission and applications. With a thermal design power of only 20-65W, the TES-3085U fulfills demands for both performance and energy saving.


Excellent hardware: immensely, durable & compact

The TES-3085U supports SAS 12Gb/s 3.5"/2.5" drives, allowing for SAS 12Gb/s and SATA 6Gb/s hard drives and SSDs. Businesses can create the most cost-effective storage by implementing suitable drives based on their needs.


5-year warranty: Global warranty inclusive

The TES-3085U is backed by a 5-year warranty with 3-year global warranty inclusive at no extra cost. This premier warranty demonstrates QNAP's dedication to the essential business needs of continuous operations and non-interrupted services to their users.


Dual OS options system inside a single rackmount NAS

The TES-3085U provides flexibility for choosing between uncompromising reliability and greater versatility. The QES operating system is suited for enterprise-level storage with maximized business continuity, or the QTS operating system for enjoying application storage for greater functionality.


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.
