QNAP ES2486dc-2142IT-128G 24-Bay, 2U Rack-mountable NAS with 1.90 GHz Intel Xeon CPU and 128GB RAM
$37,635.00 inc. GST
Powerful and cost-efficient Intel® Xeon® D based Enterprise ZFS NAS, optimized for inline deduplication and all-flash applications
Available on back-order
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.
Intel® Xeon® D dual active-active controllers provide superb uptime and redundancy to ensure high availability (HA).
Battery-protected DRAM write to cache data protection and flash read acceleration provides industry-leading random access performance.
PCIe expandability allows for 10GbE/25GbE/40GbE adapters to increase application performance.
Four 10GbE SFP+ ports accelerate large file sharing and intensive data transfer from virtualization or datacenter.
Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.
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.
With two HA systems you are paying twice the price, and the HA system can cause load imbalances because workloads are only processed on the active system. Moreover, a power outage can cause data loss, while network disconnections will invalidate the HA architecture.
Both controllers of the ES2486dc can carry traffic, along with Copy-To-Flash protection against power failure and the dual-path SAS interface design. Besides conserving computing resources, a high-speed, uninterrupted, and high-availability storage service is also provided through communication protocols such as SMB, NFS and iSCSI.
