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, such as mission-critical file servers, virtualization servers, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup and recovery.

  • Dual active-active controllers

    Intel® Xeon® D dual active-active controllers provide superb uptime and redundancy to ensure high availability (HA).

  • Reliable & High-performance

    Battery-protected DRAM write to cache data protection and flash read acceleration provides industry-leading random access performance.

  • Flexible PCIe expansion

    PCIe expandability allows for 10GbE/25GbE adapters to increase application performance.

  • 10GbE connectivity

    Four 10GbE SFP+ ports accelerate large file sharing and intensive data transfer from virtualization or datacenter.

  • Data protection & recovery

    Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.

  • Virtualization applications

    Supports VMware® vSphere® 6.5, Windows Server® 2019 and Citrix® XenServer® 7.0 for storage virtualization. Compatible with OpenStack® cloud environments.

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.

PCIe expansion for 25GbE high-speed networks

The ES2486dc provides two PCIe Gen 3.0 x8 slots connected to the CPU, allowing you to install lightning-fast 10GbE/25GbE network cards to boost virtualization, media streaming, and other bandwidth-demanding applications. Installing a Smart NIC that supports iSER can improve VMware® virtualization performance. You can also install a SAS expansion card ( SAS-12G2E ) for connecting up to seven 16-bay EJ1600 v2 expansion enclosures to seamlessly expand potential storage capacity to over 1PB, with unprecedented performance of up to 48 Gbps per host connection.

ES2486dc

Self-Healing ensures data integrity and reliability

Designed with a focus on data integrity, the QES-based ES2486dc uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects, firmware bugs or metadata errors. If data integrity violations are detected, QES automatically repairs the data with data from the other mirror before passing it to applications.
