QNAP ES2486dc-2142IT-96G, 2U, 24-Bay ZFS NAS, Dual Conrtroller, Intel Xeon D-2142T, 96GB, 3x 1Gb, 4x 10Gb SFP+

Powerful and cost-efficient Intel® Xeon® D based Enterprise ZFS NAS, optimized for inline deduplication and all-flash applications 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, such as mission-critical file servers, virtualization servers, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup and recovery. Intel® Xeon® D dual active-active controllers provide superb uptime and redundancy to ensure high availability (HA). Battery-protected DRAM write to cache data protection and flash read acceleration provides industry-leading random access performance. PCIe expandability allows for 10GbE/25GbE/40GbE adapters to increase application performance. Four 10GbE SFP+ ports accelerate large file sharing and intensive data transfer from virtualization or datacenter. Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time. Supports VMware® vSphere® 6.5, Windows Server® 2019 and Citrix® XenServer® 7.0 for storage virtualization. Compatible with OpenStack® cloud environments.
