Air Cooling: KR2266-X2-A0-R0-00


The KR2266V2 is a 2U dual-socket storage-optimized server. It adopts an innovative three-tier storage architecture, which boosts the storage density, computing performance, network bandwidth, and intelligent management. It is highly applicable to scenarios such as big data, CDN, hyper-convergence, and distributed storage.

Key Features
  • High-density storage

    The server supports up to 38 drives in a 2U space. Compared with a traditional 12-drive 2U server, its storage density is increased by 158% (max. SSD:HDD ratio = 1:2) to deliver large capacity, high-density storage, and high cache benefits.

  • Ultra-high computing power

    The server supports two 4th Gen Intel® Xeon® Scalable processors at up to 350W TDP. The server's computing performance is up to 60% higher than its predecessor, meeting the demand for ever-higher computing power in big data analysis.

  • Large bandwidth

    The data rate of PCIe 5.0 cards reaches 32 GT/s - a 200% increase over PCIe 3.0 cards. With outstanding I/O scalability, the server supports 400 Gb low-latency networks.

  • Intelligent environment perception

    With a professional hardware and software design, the server can monitor the temperature, airflow, and air pressure of its operating environment in real time, and intelligently adjust the cooling strategy accordingly. This helps prolong the service lifecycle of drives and ensures that the storage server is always running optimally. Further, it provides AI fault prediction and recommended troubleshooting schemes for the storage media to ensure the stable operation of the system.
