QNAP ES2486dc 24-drive All-flash NAS Announced

by Lyle Smith

QNAP Systems has announced the ES2486dc 24-drive bay all-flash storage solution, the newest addition new to the company’s enterprise ZFS NAS series. Designed to fulfill mission-critical file servers, virtualization servers, and commercial cloud applications, the new ES2486dc is QNAP’s first high-availability NAS that features all-flash arrays and is highlighted by dual controllers with Intel Xeon D-2142IT processors and 10GbE connectivity. The new storage solution also leverages the QES 2.1.1 operating system, which uses ZFS and supports of block-based inline data deduplication and inline compression.


QNAP Systems has announced the ES2486dc 24-drive bay all-flash storage solution, the newest addition new to the company’s enterprise ZFS NAS series.

The new storage solution also leverages the QES 2.1.1 operating system, which uses ZFS and supports of block-based inline data deduplication and inline compression.

The ES2486dc uses dual active-active controller architecture to promote “near-zero downtime high availability”. Each controller is equipped with four 10GbE SFP+ LAN ports and eight RDIMM slots, amounting up to a generous 512GB of memory. This battery-protected DRAM can write to cache data protection, which reduces data loss risks during unexpected shutdowns and failures. The ES2486dc also features:

  • Two PCIe slots support 10GbE/25GbE/40GbE network cards to boost virtualization and other bandwidth-demanding applications.
  • An optional SAS expansion card for connecting multiple EJ1600 v2 expansion enclosures to expand potential storage capacity to over 1 PB.
  • An optional QDA-SA3 6 Gbps SAS to SATA drive adapter, which allows supports SATA 6 Gbps SSDs in the 2.5-inch SAS drive bay
  • Supports VMware, Microsoft and Citrix®virtualization, SnapSync and VMware Site Recovery Manager (SRM) to offer enterprise-class remote backup and disaster recovery solution for virtual applications

The QES operating system is optimized for all-flash storage arrays and performs efficient data reduction with inline data deduplication and inline data compression. QNAP indicates that this will be beneficial for reducing I/O and SSD storage consumption, which can drastically extend the lifespan of an SSD.
