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.
Intel® Xeon® D processor optimizes performance and efficiency
Powered by an advanced 14nm Intel® Xeon® D 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-1885U delivers outstanding performance for data transmission and applications. With a thermal design power of only 20-65W, the TES-1885U fulfills demands for both performance and energy saving.
QES operating system based on FreeBSD & ZFS
The TES-1885U 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-1885U, and provides the best storage solution jointly with the current QNAP NAS.
Note: TES-1885U requires at least 32GB RAM to run QES operating system.
ZFS – the best 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 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-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.
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-1885U and one server for it to be operational.
Ideal backup NAS for Enterprise ZFS NAS
When running the QES operating system, the TES-1885U is the perfect 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 the best option to pair with the Enterprise ZFS NAS as a backup NAS to achieve optimal recovery time objectives.
