Description
The ES2486dc Enterprise ZFS NAS is QNAP’s first high-availability NAS with all-flash arrays and dual active controllers. Powered by an Intel® Xeon® D-2142IT 8 cores/16 threads processor, the ES2486dc supports up to 24 x 2.5-inch SAS 12Gbps SSDs and provides excellent I/O throughputs. Random write performance for all-flash arrays is further driven by the flash-optimized QES 2.1.1 operating system that comes pre-installed on the ES2486dc. The QES uses ZFS to support logical volume management; block-based inline data deduplication and inline compression reduce I/O and SSD storage consumption, which significantly extends SSD lifespan with higher price-performance ratio for all-flash storage arrays. Coupled with near-limitless snapshots and SnapSync for data protection, the QES-based ES2486dc fulfills demanding business applications.
Active-Active high availability with optimal storage efficiency
In Active-Active storage system architecture, both controllers can provide a comprehensive range of services, which is different from the Active-Standby architecture of single-controller systems. An advantage of Active-Active architecture is the lack of idle computing resources. To leverage the strengths of the ES2486dc Active-Active controller architecture, QNAP recommends creating multiple storage pools and distributing ownership between both controllers to enable simultaneous output from both controllers for improved load balancing.
QES 2.1.1: ZFS-based, and optimized for all flash performance
The ES2486dc features the QES (QNAP Enterprise Storage) 2.1.1 operating system which is based on the simple and efficient FreeBSD kernel and ZFS file system for high-end enterprise applications. QES 2.1.1 not only provides reliable data protection, recovery, and business-class features, it is also optimized for flash storage to drive outstanding performance of all-flash storage arrays, accelerating mission-critical services and eliminate challenges in VDI environments. QES 2.1.1 also comes with Quality of Service (QoS) capabilities to ensure consistent primary storage performance in multi-application environments. The flash-optimized QES 2.1.1 continues the same user experience as the intuitive QTS, thus easy to learn for enterprise users and can be quickly implemented into existing IT infrastructures.
