Product Description

Quickly and easily find documents, photos, videos, and music with Qsirch, QNAP's new built-in NAS search application lets you find what you need by real-time, natural search. Simply type in as much as you know about what you are trying to find, including bits of the file name or even words/phrases in the document, and Qsirch will display a list of matches, complete with thumbnails, as you type. Qsirch even remembers your search history so you can quickly navigate to files you've previously searched for. Qsirch is a huge productivity boost - it greatly reduces the amount of time spent looking for files on the NAS so you can focus on other tasks. The TS-853U supports SSD caching which can greatly boost the IOPS performance of storage volumes. It is perfect for improving the overall workflow of IOPS-demanding applications such as virtualization. The business-ready TS-853U is designed to provide 24/7 operations and services. The support for comprehensive RAID configurations and hot-swapping allow for replacing hard drives without service interruption. QNAP's advanced RAID recovery technology also helps if any healthy drives are removed from a degraded RAID volume by mistake. The system can be recovered by reinserting the wrongly removed hard drives so the data can still be accessible. The TS-853U delivers high reliability and efficiency with 4 LAN support for multiple port-trunking modes including fail-over support. The TS-853U supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac, Linux/UNIX networks. Data, logs and ISO images of CDs and DVDs can be centrally stored on the TS-853U and protected by an integrated antivirus solution. The Windows AD and LDAP services enable system administrators to configure user permissions by using an existing Windows AD server, LDAP server or built-in LDAP service. The TS-853U supports SAMBA v4 and can act as a Windows domain controller to manage privilege settings.
