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

The ES2486dc is QNAP’s first high-availability NAS with all-flash arrays that feature dual controllers with Intel Xeon D-2142IT processors to provide high I/O throughputs along with 10GbE connectivity. It is driven by the flash-optimized QES 2.1.1 operating system that uses ZFS and includes the support of block-based inline data deduplication and inline compression.

Featuring a dual active-active controller architecture, the ES2486dc ensures near-zero downtime high availability. Each controller provides four 10GbE SFP+ LAN ports and eight RDIMM slots for up to 512 GB 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 1 PB. Leveraging the optional QDA-SA3 6 Gbps SAS to SATA drive adapter, the ES2486dc allows the usage of a SATA 6 Gbps 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.

The ES2486dc Enterprise ZFS NAS features the QES operating system 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 Quality of Service to ensure consistent primary storage performance.

The ES2486dc supports VMware, Microsoft and Citrix virtualization, and SnapSync supports VMware Site Recovery Manager (SRM) to offer remote backup and disaster recovery 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.
