Description
ES2486dc
Powerful and cost-efficient Intel® Xeon® D based Enterprise ZFS NAS, optimized for inline deduplication and all-flash applications
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.
Dual active-active controllers
- Intel® Xeon® D dual active-active controllers provide superb uptime and redundancy to ensure high availability (HA).
Reliable & High-performance
- Battery-protected DRAM write to cache data protection and flash read acceleration provides industry-leading random access performance.
Flexible PCIe expansion
- PCIe expandability allows for 10GbE/25GbE adapters to increase application performance.
10GbE connectivity
- Four 10GbE SFP+ ports accelerate large file sharing and intensive data transfer from virtualization or datacenter.
Data protection & recovery
- Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.
Virtualization applications
- 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.
Active-Standby single-controller system
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.
- Experience unmatched performance, built-in security and remote management capabilities with Intel Xeon 1.90 ghz processor
- RAID technology - data reliability, fault tolerance and improved overall performance
- Gigabit Ethernet is very resourceful when a large number of file transfers are required, such as when performing backups over a network
