KR2280V2

Supports 4th Gen Intel Xeon Scalable processors in delivering excellent computing, storage and scalability; provides front and rear I/O maintenance to overcome the O&M bottlenecks of the traditional data centers; integrates various advanced technologies from the industry to introduce the efficient liquid-cooling, EVAC, etc.; and upholding open innovation, extreme improvement, low power consumption, and intelligence & efficiency, flexibly meets the needs of diverse scenarios

Key Features
  • Excellent Performance and Efficient Computing

    Equipped with the 4th Gen Intel Xeon Scalable processors, supports up to 60 cores and 120 threads per CPU with up to 350W TDP and a max Turbo frequency of 4.2 GHz through 4 UPI links at 16 GT/s. 

    Supports up to 32 DDR5 ECC DIMMs (4,800 MT/s, RDIMMs) in delivering high speeds and superior availability.


  • Break-thru Design and Full-scenario Adaptability

    Offers ultimate computing, storage and network performance, and delivers flexible combination through modular design to support 45 × 2.5-inch drive or 20 × 3.5-inch drive and the optional rear M.2/E1.S SSD for diverse storage demands, and to support PCIe 5.0/4.0 for different scalability requirements, with up to 20 PCIe expansions. 

    Supports up to 2 to 3 optional hot-swappable OCP 3.0 modules, and provides 1Gb, 10Gb, 25Gb, 40Gb, 100Gb, 200Gb, and 400Gb network interfaces. 

    With Compute Express Link (CXL), an open-source and standard cache-coherent interconnect protocol, and E3.S storage medium, provides caching media apart from traditional DIMMs to meet the core needs of large-capacity cache services.


  • Flexible Architecture and Security & Intelligence

    The front I/O design enables O&M engineer to operate in the cold aisle, which simplifies O&M procedures, prolongs the service lifecycle of thermo-sensitive components such as optical modules and smart NICs, and improves data stability. 

    The redundancy design of core components, such as the BIOS and BMC, ensures that the system can start by switching to the standby chip, and supports the online upgrade of the BMC without suspending services, thus guaranteeing service continuity. 

    Adhering to the intelligent O&M, the cloud-based O&M and the online diagnosis can greatly simplify the difficulty in data center O&M and lower the O&M cost.


  • High Efficiency, Carbon Emission Reduction, and Low Power Consumption

    Supports efficient heat dissipation schemes such as cold-plated cooling and EVAC, and provides the data centers with the comprehensive liquid-cooling solutions. 

    By working with KAYTUS's unique intelligent zone-oriented control technology, delivers energy-saving fan speed regulation and accurate air supply according to recent regional workload changes. 

    With the focus on environmental protection, key server components meet the lead-free requirements (RoHS), and all packaging materials are recyclable.
