QNAP ES2486dc-2142IT-128G
The QNAP ES2486dc-2142IT-128G NAS serves as enterprise all-flash storage with dual Active-Active controllers for secure data storage and virtualisation. The device features 24 bays for 2.5-inch hard drives or SSDs with a SAS or SATA interface. The system is powered by an eight-core Intel Xeon D-2142IT processor with a frequency of 1.9GHz, which can boost up to 3GHz. The maximum memory capacity is 1024GB (a total of 16 modules of 64GB), with each of the two controllers supporting up to 512GB of RAM (8× 64GB). The rack-mounted design takes up 2U of rack height. Each of the two controllers offers two PCIe Gen 3.0 ×8 expansion slots. These slots allow for the installation of 10GbE or 25GbE network cards to increase throughput. You can also install SAS expansion cards into the slots to connect additional JBOD disk units. This way, you can increase the total capacity up to one petabyte. The device meets the requirements for operation in virtualisation infrastructures. The storage supports Microsoft Hyper-V technology. The integration of the iSER interface helps to reduce the processor load during data transfer between servers. This enables the system to handle demanding database operations and virtual desktop operations.

Dual architecture of the QNAP ES2486dc-2142IT-128G
The system uses two active controllers that simultaneously process network traffic and share the workload. This design eliminates unused hardware resources and prevents network bottlenecks. If one controller fails, the backup unit takes over all system services without interrupting operation. Power is supplied by two redundant power sources.
QES operating system
The platform uses an operating system that combines the FreeBSD kernel and the ZFS file system. This software provides advanced features for managing data arrays and optimises writing to flash drives. The system uses a Write Coalescing algorithm to transform random writes into sequential writes, thereby extending the life of the installed SSDs.
Data reduction technology in the QNAP ES2486dc-2142IT-128G
The storage integrates inline deduplication, compression, and compaction of data directly during writing. These processes significantly reduce the capacity demands on physical disks and save storage space. The technology efficiently removes duplicate data blocks before they are stored on the SSD. This is particularly helpful in environments with a large number of virtual machines.
Data integrity protection
The ZFS file system performs continuous data integrity checks using checksums at all levels. The system automatically detects silent data corruption caused by firmware or hardware errors. Upon finding corrupted data, it initiates a self-healing process using redundant copies. This ensures that data always reaches applications in an intact state.
