TES-1885U-D1531-64G-US - 12 (+6) Bay 10GbE NAS and iSCSI/ IP-SAN with dual OS options (QES/QTS), SAS 12G, SAS/SATA 6G, Xeon D-15
by QNAP

Powered by an Intel® Xeon® D processor, the powerful enterprise-class TES-1885U-D1531-64G-US 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.
