The QNAP ES2486dc Enterprise ZFS NAS Array is a high-availability NAS with all-flash arrays and dual active controllers. Powered by an Intel Xeon D-2142IT 8-core processor, the ES2486dc supports up to 24 2.5" SAS 12 Gb/s SSDs and provides powerful 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 a higher price-to-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, such as mission-critical file servers, virtualization servers, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup and recovery.
