QNAP TES-1885U-D1531-16GR-US Diskless 18 Bay NAS Server, Intel® Xeon® Processor D-1531, 6-core 2.2 GHz, 16GB ECC RAM ( 8GB RDIMM x 2 ), 10GbE supported, 256GB mSATA cache module supported, VMware, Citrix and Hyper-V ready
Powered by an Intel® Xeon® D processor, the powerful enterprise-class TES-1885U 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-1885U gives the flexibility to choose from two operating systems, enabling businesses to deploy proper operating systems on multiple TES-1885U based on their needs and goals in different stages.
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.

Configured system orders start here!
The selected drives are batch controlled and tested using our HDD and SSD servers. Passed drives are then installed in the NAS with Volume and RAID set. Our pre-burn testing prepares the NAS with an initial system and drive testing cycle to ensure that the integrity of the entire system is tested and passed with no issues at all.
Our stress testing (burn-test) cycle commences for a minimum of 24 hours and extends to 48 hours if requested or required. This is undertaken in order to ensure stability when used in a normal environment. These tests can include extremes of workload (constant I/O's), CPU and memory use, thermal load (heat), clock speed, or voltages, bus and connectivity components, with the primary stress testing software aiming to test stability by trying to force a system to fail. Our tests put a greater emphasis on robustness, availability and error handling heavy loads.
Once the tests are complete we QA and pack the system back into it's retail box. Then it's double boxed to protect the unit during shipping. You receive your QNAP NAS Ready To Plug 'N' Store. It doesn't get any easier. Buy your NAS from the QNAP EXPERTS at QNAP DIRECT.
