Qnap AFA: ES2486dc Enterprise ZFS 2U Rackmount 24-Bay 2.5-Inch SAS NAS With Xeon D Dual Active-Active Controllers

To meet demands for all-flash storage systems in high-end storage, Qnap Systems, Inc. has added a 24-drive bay all-flash storage solution ES2486dc to its Enterprise ZFS NAS series.

The ES2486dc is the company’s first HA NAS with AFAs that feature dual controllers with Intel Corp.‘s Xeon D-2142IT processors to provide high I/O throughputs along with 10GbE connectivity. Driven by the flash-optimized QES 2.1.1 OS that uses ZFS and includes the support of block-based inline data deduplication and inline compression, it provides future-proof IT architecture with flash storage to fulfill mission-critical file servers, virtualization servers, and commercial cloud applications.

“The all-flash ES2486dc reduces performance bottleneck, and its dual controllers enhance system reliability for uninterrupted mission-critical enterprise tasks and productivity,” said David Tsao, product manager, Qnap, adding “The robust ES2486dc further incorporates the powerful ZFS, making it an excellent integration of hardware and software as a capable, trustworthy, and cost-efficient all-flash storage solution for businesses.“

Featuring a dual active-active controller architecture, the ES2486dc ensures near-zero downtime HA. Each controller provides 4 10GbE SFP+ LAN ports and 8 RDIMM slots for up to 512GB memory. Battery-protected DRAM write to cache data protection helps reduce data loss risks. Two PCIe slots support 10GbE/25GbE/40GbE network cards to boost virtualization and other bandwidth-demanding applications.

Users can also install a SAS expansion card for connecting multiple EJ1600 v2 expansion enclosures to expand potential storage capacity to over 1PB. Leveraging the optional QDA-SA3 6G SAS to SATA drive adapter, the AFA allows the usage of a 6Gb SATA SSD in the 2.5-inch SAS drive bay, enabling SATA SSDs to share the SAS dual-port advantages for fault-tolerant enterprise storage environment and assisting organizations to establish a performing and cost-effective AFA system.

The ES2486dc Enterprise ZFS NAS features the QES OS that is optimized for all-flash storage arrays. It performs data reduction with inline data deduplication and inline data compression, beneficial for reducing I/O and SSD storage consumption and extending SSD lifespan. More advanced business features include self-healing for silent data corruption, near-unlimited snapshot versions, SnapSync for instant remote backups, and QoS to ensure consistent primary storage performance.

The product supports VMware, Microsoft and Citrix virtualization, and SnapSync supports VMware Site Recovery Manager (SRM) to offer enterprise remote backup and DR solution for virtual applications. The support of iSER optimizes VMware performance, and the compatibility for OpenStack Cinder and Manila file sharing services provides businesses with a flexible, and low-cost storage solution for OpenStack environments.
