By David Leung, Sr. Manager Product Management
As the flagship product of KAYTUS 2U dual-socket servers, the KR2280V2 leads the industry by supporting three major processor platforms with innovative system architecture, including latest Intel® Xeon®, AMD EPYC™, and AmpereOne. This realizes a significant performance improvement in scenarios such as AI Large Language Models, virtualization, and cloud-based gaming. Through in-depth optimization at the system, component, circuit, and firmware levels, it provides users with leading computing power support that is high-performance, energy-efficient, reliable, and cost-effective.
One server supporting three processor platforms, optimized for diverse application scenarios
With the rapid development of the digital economy, diverse application scenarios lead to a demanding requirement for computing power, especially in AIGC-oriented AI applications, which place higher demands on computing performance. In diverse application scenarios, the KAYTUS KR2280V2, with a focus on system design, incorporates state-of-the-art computing, storage, and network technologies. It supports three types of processors: the latest Intel, AMD, and Ampere (ARM architecture), enabling flexible configurations of storage, I/O, and heterogeneous modules. This versatility covers a wide range of business scenarios, from general computing to heterogeneous computing and from storage-oriented to I/O-oriented applications.
The KAYTUS KR2280V2 fully leverages the AI acceleration engines like AMX/DSA supported by the 5th Gen Intel® Xeon® processors. It adopts new DDR5 memory with an 87% increase in bandwidth compared to DDR4. The L3 cache functionality triples the cache capacity, overcoming bottlenecks in data transfer between the CPU and memory. It also adopts the highest PCIe 5.0 I/O interconnection rate in the industry, maximizing throughput between the CPU and other components, significantly reducing latency, and improving data access efficiency by 20%-30%. In application scenarios such as speech and image recognition, it achieves over a 42% improvement in AI inference capabilities. In LLaMA2 7B/13B large model inference scenarios, performance can be boosted up to 270%.
For high-core, high-performance requirements in scenarios including virtualization, cloud computing, rendering, and scientific research, the KAYTUS KR2280V2 can be equipped with two 4th Gen AMD EPYC™ processors, harnessing the advantage of up to 256 cores. It offers a 125% increase in memory bandwidth and a 50% increase in L3 cache and supports various storage solutions such as E3.S, U.2, U.3, and SATA/SAS. It provides flexible network interfaces to meet the demands of high computing performance, high network bandwidth, and large memory capacity. The overall performance is increased by up to 123%. In scientific computing scenarios like VASP applications, the performance is improved by up to 250% compared to the previous generation, better supporting scientific calculations involving hundreds of atoms or even larger systems. Applications like WRF and CFD experience a performance boost of up to 350%.
The KR2280V2 also supports the ARM architecture's AmpereOne processor, with a single CPU supporting 192 cores. Based on the RISC CPU design, this computing platform has a natural advantage in lightweight instructions, achieving higher core efficiency. It provides more core packaging, and all cores can run at a constant frequency. Each core is designed as a single-threaded unit, ensuring maximum resource isolation in cloud services. The performance scales linearly without degradation.
Air and liquid cooling compatibility, a 70% reduction in overall system cooling power consumption
Servers are core elements in data centers. Their overall power consumption can account for 40%-50% of the total energy consumption. The KAYTUS V2 servers consistently adhere to green design principles. KR2280V2, a flagship dual-socket model, supports air and liquid cooling designs. It optimizes heat dissipation while maintaining the original performance, reducing power consumption for cooling.
Currently, the KR2280V2 has introduced cold-plated liquid cooling, resulting in a 70% reduction in overall system cooling power consumption compared to air-cooled servers. It also includes leak detection for compute nodes and cabinets, significantly improving the overall system's RAS (Reliability, availability, and serviceability) features. Additionally, to meet different scenarios' I/O requirements, the air cooling mode supports up to 13 PCIe 5.0 interfaces, while the liquid cooling mode supports 7 PCIe 5.0 interfaces, providing exceptional IO resources. In response to the varying specifications and standards of liquid cooling equipment in the market, KR2280V2's liquid cooling module is designed to be compatible with multiple mainstream liquid cooling quick-connect solutions. This not only meets the requirements for complete cabinet delivery solutions, but also enables more flexible decoupling from liquid-cooled cabinets, striking a balance between performance, maintainability, and cost-effectiveness. The liquid-cooled version of KR2280V2 is better equipped to meet data center requirements for green and low-carbon solutions. Its flexible configurations and optimized cooling design allow it to handle high loads and various complex application scenarios more effectively.
The air-cooled version of KR2280V2 features an optimized system cooling design. In addition to the traditional temperature control, it incorporates a composite cooling control based on device power, which enhances energy efficiency, effectiveness, and stability. It utilizes a unique system energy-saving design, including over 400 sensors, various efficient heatsinks, component-level precise detection for intelligent control, server system partition intelligent control technology, and optimization of airflow in the exhaust channel. Based on the system's energy-saving design, it can intelligently control temperatures based on the power consumption of components in different airflow passages, achieving low-latency, partitioned, and intelligent control of the fan speed, improving overall cooling efficiency.
In summary, the KR2280V2 sets the industry design reference for dual-socket servers. It spans three major computing platforms, covers various application scenarios, meets high-standard PUE requirements, and undergoes in-depth optimization from component to system levels. Continuous refinement in design has resulted in the exceptional performance of the KR2280V2. It caters to the growing demands for digitization and intelligence across various industries, making it a solid foundation for users to transition and upgrade in the era of intelligent computing.
