The QNAP Enterprise ZFS NAS ES1640dc features the new FreeBSD-based QES operating system which provides flexible storage pools, simplified management, high-performance SSD cache, near-limitless snapshots, SnapSync, block-based data deduplication, in-line compression and thin provisioning with reclaim.
It is designed for virtualisation and virtual desktop environments.
"VDI applications usually contain lots of duplicate data, and block-based data deduplication and data compression can help reduce storage usage, achieving optimal virtual desktop performance as deduplicated virtual desktops become easier to cache," said product manager Waterball Liu.
The ES1640dc is also certified for VMware vSphere 6.0 and is compatible with Microsoft Hyper-V. VMware VAAI and Microsoft ODX are supported for increased performance. The QNAP vSphere Client plug-in, web plug-in and QNAP SMI-S provider simplify the management of virtualisation environments.
On the hardware side, ES1640dc features Intel Xeon E5-2420 v2 processors, 32GB RAM, battery-protected DRAM write cache, dual 10GbE ports, redundant power supplies and dual active-active controllers for "near-zero downtime". The 40Gb ethernet is optional.
The 3U chassis accommodates 16 SAS hard drives or SSDs. SATA SSDs can be used by adding the optional SAS-to-SATA interposer.
"The ES1640dc adopts dual active-active controllers to provide the utmost reliability and high availability," said Liu.
Similarly, the EJ1600 expansion enclosure connects via dual path mini-SAS for continuous operation in the event one of the cables is disconnected.
"The new QES operating system provides superior system functionality, but also provides a similar user experience as our well-reputed QTS operating system to make it easier for existing QNAP NAS users to learn the system," added Liu.
