QNAP's latest NAS includes OpenStack support


Consumer and small business NAS vendor QNAP is moving into the enterprise market.

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.

OpenStack support includes iSCSI Cinder Node drivers and provides block-level storage space to virtual machines.

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.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
