The KR1280V2 series maximizes the performance, computing density, and scalability in a 1U space and is suitable for a variety
of computing-intensive service scenarios such as high-performance computing and virtualization. With rich storage matrices,
the KR1280V2 meets the needs of scalability and network balance to the greatest extent. It also satisfies the low-PUE needs of
more high-density data centers by integrating multi-dimensional cooling solutions such as air cooling, cold plate cooling, and
immersive cooling in the 1U models.
Excellent performance and high efficiency
Built on the 4th Gen Intel® Xeon® Scalable processors, the KR1280V2 series supports up to 60 cores and 120 threads per CPU with
a TDP of up to 350 W 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) to deliver high speeds and superior availability.
Flexible configurations and outstanding scalability
The KR1280V2 series supports up to 12 2.5-inch SAS/SATA/NVMe drives or 32 E1.S SSDs at the front, and up to 2 2.5-inch
SAS/SATA drives at the rear (refer to the specific configurations).
Supports PCIe 5.0/4.0, up to 2 optional hot-swappable OCP 3.0, and provides 1 Gb, 10 Gb, 25 Gb, 40 Gb, 100 Gb, 200 Gb, and 400 Gb
With Compute Express Link (CXL), an open-source and standard cache-coherent interconnect protocol, and E3.S storage medium,
the KR1280V2 provides caching media in addition to traditional DIMMs to meet the core needs of large-capacity cache services.
Security, reliability, and smart O&M
The front I/O design enables O&M personnel to operate in the cold aisle, which simplifies O&M operations, extends the service life
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 flash, ensure 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.
High efficiency, carbon emission reduction, and energy conservation
Supports cold plate cooling and immersive cooling, and provides comprehensive liquid-cooling solutions for data centers. With
full-stack liquid-cooling capabilities, the KR1280V2 series can drop the PUE of data centers to below 1.1.
By working with unique zonal intelligent control technology, the KR1280V2 series can adjust the fan speed intelligently
based on the power consumption of components in different air ducts, eliminating temperature transmission delays and realizing
energy-saving fan speed regulation and accurate air supply.
With the focus on environmental protection, key components of the series meet the lead-free requirements (RoHS), and all
packaging and packing materials are recyclable.
