The Enterprise-class TES-1885U 18-Bay NAS Enclosure from QNAP is designed so that businesses may choose from two operating systems - either the FreeBSD-based QES or Linux-based QTS - and, based on their needs and goals, deploy the proper OS on multiple TES-1885U units. While QES supports ZFS for the strong 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 apps to realize storage efficiency and diverse usage applications. Please be aware that 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.
The TES-1885U holds larger-capacity 2.5"/3.5" hard drives in twelve drive bays that support SAS-3 12 Gb/s and SATA III 6 Gb/s and also supports faster SSDs in six 2.5" SATA III bays. While the twelve 2.5"/3.5" drive bays can only be used for data storage, the six 2.5" bays can be used for caching, high-performance storage pools, or the QES OS drive. To manage the data and operating system, this NAS is powered by a 2.2 GHz Intel Xeon D-1531 six-core processor along with 32GB of 2133 MHz DDR4 non-ECC RAM. This version of the TES-1885U is also outfitted with two 10 Gigabit Ethernet SFP+ ports, four Gigabit Ethernet ports and three PCIe 3.0 slots and one PCIe 2.0 slot, each of which supports 10 or 40 Gigabit Ethernet adapters and PCIe NVMe SSDs.
You can configure your drives in a RAID array, such as RAID 0, 1, 5, 6, 10, 50, 60, RAIDTP, Triple Mirror and Global Hot Spare, providing additional storage options that might not be available on other storage units. You can activate the Tiered Storage feature, which moves frequently-used "hot" data to high-performance storage tiers and less-accessed "cold" data to the higher capacity drives.
QNAP's TES-1885U is powered using dual redundant 450W power supplies that operate at 90~264 VAC and stays cool using four 6cm smart cooling fans. Included are four Ethernet cables, two power cords, flathead screws for 3.5" and 2.5" drives and an A03 Series Chassis Rail Kit. Protection is provided by a limited 5-year warranty, which is inclusive of 3-years of global coverage.
