QNAP ES2486dc-2142IT-96G
QNAP ES2486dc-2142IT-96G
The Enterprise NAS QNAP ES2486dc-2142IT-96G is designed for data storage and management in a corporate environment. This system uses two active controllers for high availability and to minimise critical service downtime. The device supports all-flash configurations and offers advanced data protection features. Each of the two controllers contains an octa-core Intel Xeon D-2142IT processor. The active-active architecture effectively distributes the load between both nodes without creating any bottlenecks. The system can hold up to 24 2.5" hard drives or SSDs and provides read speeds of 12473MB/s and write speeds of 4923MB/s.

Active-active architecture and the QNAP ES2486dc-2142IT-96G
The system operates using two active controllers that share the workload. Unlike active-standby systems, the active architecture efficiently uses all hardware resources without needing to initiate a backup node. Both controllers provide services simultaneously, increasing throughput and balancing the network load. This approach prevents bottlenecks and helps maintain smooth application performance even if one module fails, as the other instantly takes over all operations.
Powerful Intel Xeon processor
Each controller contains an octa-core Intel Xeon D-2142IT processor with a frequency of up to 3GHz. This hardware delivers high computing power for real-time data deduplication and compression. The device handles demanding tasks in an all-flash environment while maintaining low latency. The x86 architecture processor works with the 96GB of system RAM, which can be expanded up to 1024GB (512GB per controller) if needed, for greater cache capacity and smoother processing of demanding data operations.
QuTS hero operating system on the QNAP ES2486dc-2142IT-96G
The device runs on the QuTS hero operating system, which uses the ZFS file system. This system provides advanced features for data reduction and maintains the integrity of stored files. Users have access to tools for rapid disaster recovery. The operating system supports up to 65536 snapshots for iSCSI LUN and shared folders, which simplifies version management over time. The system is optimised for all-flash arrays and accelerates demanding enterprise databases.
Data protection and self-healing functions
The ZFS file system automatically detects and repairs silent data corruption caused by hardware errors. Using checksums, the system verifies file integrity and, if an error is detected, restores the data from its mirror. This prevents the loss of important information in a corporate environment. Additionally, Copy-to-Flash protection with battery backup support protects data in the DRAM cache from sudden power loss by writing it to internal M.2 SSDs.
Fast network connectivity and efficient SSD capacity utilisation
Each controller has four integrated 10GbE SFP+ ports for high-speed transfers. Two free PCIe Gen 3.0 slots are available for installing additional network cards with speeds of up to 25GbE. This facilitates integration into existing data centre infrastructure and virtualisation environments. Expansion cards enable the connection of TL-R1620Sdc JBOD enclosures, increasing physical storage capacity via the mini-SAS interface. Inline deduplication, compression, and compaction technologies significantly reduce storage space requirements. These features optimise writes to hard drives and reduce wear on SSDs. The result is a longer lifespan for flash memory and lower costs for new media. The Write Coalescing algorithm converts random writes into sequential ones, increasing performance in all-flash configurations and minimising unnecessary memory cell rewriting.
