QNAP ES2486dc 24-drive All-flash NAS Announced
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.
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.
