QNAP® Systems, Inc. today announced the release of the new ES1640dc v2, an upgraded version of the Enterprise ZFS NAS designed for mission-critical IT tasks. It has been enhanced with faster 12Gb/s SAS, four built-in 10GbE SFP+ ports, two 10GbE RJ45 ports, an M.2 SSD dedicated to NVRAM, and can be expanded with the EJ1600 v2 (SAS-12Gb/s) and EJ1600 (SAS-6Gb/s) expansion enclosures for a potential storage capacity of over 1 PB. The ES1640dc v2 features a dual active-active controller architecture, Intel® Xeon® E5 processors, and ZFS for the utmost reliability and making it suited for file servers, disaster recovery, VDI, professional video streaming studios, and more versatile applications that requires near-zero downtime.

"With an easy-to-use management interface and ZFS, the upgraded QNAP Enterprise ZFS NAS provides higher-standard services for businesses that demand high-availability storage," said Waterball Liu, Product Manager of QNAP. "The Enterprise ZFS NAS especially excels in providing high availability solutions for file servers, virtualization servers, virtual desktops, online video streaming, IP surveillance, snapshots and remote recovery."

The ES1640dc v2 is powered by high-performance Intel® Xeon® E5 processors and features dual active-active controllers to provide businesses with near-zero downtime high availability. Other features include battery-protected DRAM write cache and SSD read cache to accelerate operations in virtual machines environments, an M.2 SSD dedicated for NVRAM to secure information in the event of power failure, and a PCIe slot pre-installed with a dual-port 10GbE RJ45 NIC (replaceable with a 40GbE QSFP+ NIC). The ES1640dc v2 and its corresponding expansion enclosures all provide dual-channel (Dual Path) to tolerate single node failure.

The ES1640dc v2 also runs the new QES operating system that incorporates the powerful ZFS. The highly-anticipated advanced features provided by QES include: flexible storage pools and expandability, high-performance SSD caching, near-limitless snapshots, SnapSync, block-based data deduplication, inline compression, thin provisioning with reclaim, and data self-healing.
