  • 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

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.
