Qnap Enterprise Storage V2.1.0 OS for NAS

Qnap Systems, Inc. released the QES (QNAP Enterprise Storage) 2.1.0 OS, which includes features such as: company’s Write Coalescing algorithm to optimize all-flash performance in ZFS, software-defined SSD optimization, inline compaction, iSER support, and other technologies.

Demonstrating strengths in performance, data protection, data reduction, virtualization, and the compatibility with OpenStack cloud environments, QES 2.1.0 delivers a cost-effective, flash-optimized storage solution for enterprise data centers and VDI environments.

“Enterprise demand for all-flash storage remains strong due to requirements for maximized IOPS with minimal I/O latency,” said Joe Chao, product manager, Qnap. “QES 2.1.0 is focused on unleashing the performance potential of all-flash storage, and helps organizations tackle performance bottlenecks of mission-critical applications such as data centers, virtualizations, and VDI.”

QES is based on the FreeBSD kernel and uses ZFS. In QES 2.1.0 the Write Coalescing algorithm drives a performance boost, which in the firm’s testing led to a 400% random write performance boost for the all-flash TES-3085U NAS. Support for software-defined over-provisioning allows users to allocate additional over-provisioning space to SSDs and storage pools to prevent performance degradation caused by write amplification, while also benefiting the lifespan of SSDs.

Besides reinforcing QES’ existing inline deduplication and inline compression, QES 2.1.0 achieves greater space saving by supporting inline data compaction techniques – which is especially useful when highly-repetitive data or massive small files (such as transaction logs of banks or e-commerce) are generated.

QES 2.1.0 excels in performance and also supports numerous ZFS-based data protection and DR features, including end-to-end checksums to detect and correct silent data corruption, near-unlimited snapshots for iSCSI LUN and shared folders, and SnapSync to accelerate remote backups. QES-based the company’s NAS supports VMware, Microsoft and Citrix virtualization, and the SnapSync also supports VMware Site Recovery Manager (SRM) to offer enterprise remote backup and DR solution for virtual applications.

The upgraded QES 2.1.0 adds supports for iSER to optimize VMware performance, and for OpenStack Cinder and Manila file sharing services, providing businesses with a flexible, easy-to-use, and low-cost storage solution for OpenStack environments.
