QNAP TES-1885U-D1531-16GR Overview
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 16GB of 2133 MHz DDR4 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.

Dual OS Options System Inside a Single Rackmount NAS
The TES-1885U provides flexibility for choosing between reliability and 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-1885U supports the QES (QNAP Enterprise Storage) operating system, which is based on the simple and efficient FreeBSD kernel and the ZFS file system that has been shown through years of experience to be more 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-1885U and provides a good storage solution jointly with the current QNAP NAS.

ZFS - A File System for Business Data Storage
The TES-1885U 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-1885U 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-1885U provides businesses with a cost-effective remote virtual desktop platform and mission-critical information warehousing.

Strong Disaster Recovery Made by Nearly Limitless Snapshots and SnapSync
The TES-1885U 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-1885U 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.

Backup Solutions to Secure Data
QNAP NetBak Replicator is easy-to-use and VSS-aware backup software 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-1885U and one server for it to be operational.

Storage for Comprehensive Virtualization Applications
The TES-1885U 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.

Backup NAS for Enterprise ZFS NAS
When running the QES operating system, the TES-1885U provides good backup storage for the dual-controller Enterprise ZFS NAS using SnapSync. If the Enterprise ZFS NAS unexpectedly stops, the TES-1885U 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-1885U a worthy option to pair with the Enterprise ZFS NAS as a backup NAS to achieve strong recovery time objectives.

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-1885U with Auto Tiering that helps continuously optimize storage efficiency across SSDs and SAS/SATA drives. With Auto Tiering, the TES-1885U 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-1885U 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-1885U 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-1885U 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-1885U supports SAMBA v4 and can act as a domain controller for Windows.

Backup & Disaster Recovery Solutions
