Improving the storage-to-compute ratio fills the storage capacity gap, and flexible design meets various data application needs
The Internet of Things (IoT), big data, AI, and other next-generation information technologies are empowering the process of digital transformation, giving rise to a plethora of data-intensive new applications, such as intelligent driving, real-time transactions, remote healthcare, and industrial production quality monitoring. Some of these applications require real-time data processing, some require massive storage space, and others require intelligent analysis. These new applications and scenarios continue to drive the growing demands for storage, computing, and network resources. In actual IT scenarios, there is often a mismatch between computing power and storage capacity. While computing power may be ahead, storage capacity is insufficient, leading to resource waste when seeking the compensation of the storage shortfall.
As a 2U high-density storage server, the KR2266V2 is designed to focus on the significant improvements in storage density, computing power, network bandwidth, and intelligent management. It offers a balanced and symmetrical system architecture that provides more data capacity, greater data throughput, and enhanced data processing capability. It possesses ultimate storage, computing, and network performance.
In terms of performance, the KR2266V2 single-server storage performance is 2 to 3 times that of general-purpose 2U 12-drive servers in the industry. It supports 2 latest Intel® Xeon® scalable processors with up to 350W TDP, achieving a maximum 60% improvement in computing performance compared to its predecessor, meeting the growing demands for computing power in big data analytics. In terms of I/O expansion, it supports data rates of up to 32GT/s with PCIe 5.0, a 100% increase compared to PCIe 4.0 rates, and can support 400Gb networks, delivering a low-latency application experience.
In the face of real-time recommendation, real-time risk control, and other scenarios integrating both streaming and batch processing in the Internet and financial industries, a configuration of high performance CPUs + 24 LFF drives + 4 NVMe or 24 LFF drives + 8 NVMe (8U.2/8E1.S) drives is deployed. It provides ultimate computing power, supporting up to 120 computing cores and a network bandwidth of up to 100GB. It can offer a maximum HDD: SSD ratio of 3:1, meeting the demand for tens of millions of IOPS while also providing several hundred terabytes of data storage. The use of NVMe caching improves the speed of real-time data analysis by 26%.
Taking autonomous driving as an example, its data processing includes collection and labeling processes. Autonomous vehicles with a level of automation at L3 or above generate a daily data volume ranging from 5TB to 8TB. This requires robust scalability supported by distributed storage. Additionally, the development of autonomous driving function involves extensive training. Distributed storage enhances the efficiency of GPU access to data through sending packages to the central control system from several storage nodes. The KR2266V2 meets the storage capacity requirements while providing maximum data access bandwidth and higher I/O throughput, meeting the application demands in the field of autonomous driving.
In the face of data lakehouse scenarios involving massive data storage, intelligent analysis, marketing trend analysis, inventory analysis, and ad-hoc queries, a configuration of CPUs with moderate computing power + 24 LFF HDDs is used. These 24 HDDs can be mounted under a single RAID card, fully utilizing disk performance for more stable and efficient system data transmission. Compared to the general-purpose 2U products with 12 HDDs in the industry, the single-server storage performance is improved by 116%.
For storage-compute separation scenarios, a configuration of CPUs with low computing power + 24 LFF HDDs can provide double storage density of a general-purpose server, saving more than half the data center space and reducing storage power consumption by over 45% per TB.
High-density storage design, with a storage capacity exceeding 600TB in a 2U space
The outstanding performance of the KR2266V2 in storage scenarios is attributed to its patented three-layer pull-out design for the drive bay. The server supports 28 3.5-inch drives, increasing storage density by 133% compared to the industry average. The design optimizes the drive tray, reshapes the 2U three-layer space architecture, introduces an innovative mortise and tenon frame structure, upgrades the die-casting component structure, and innovates the roller slide rail pull-out mechanism, which are all designed for storage performance improvement. To maintain signal integrity, the drive bay eliminates cable, adopts on-board routing, and utilizes an I/O board design. Additionally, the KR2266V2 incorporates a significant number of Redriver chips to enhance the storage data link driving capabilities, improving the overall storage link performance and ensuring that each drive can achieve maximum performance.
From components to the system, the KR2266V2 ensures stability and reliability in all aspects. This includes disrupting traditional vertical backplane design by adopting a flat drive backplane design, which reduces air resistance and ensures more stable drive operation. By suppressing resonance, improving fans, and implementing a vibration buffering design, it enhances drive performance by over 17%. Furthermore, the drive tray structure adopts an integrated metal casting design, meeting the product's structural reliability requirements. It has undergone authoritative institution's Level 9 seismic resistance testing, and adopts a design that ensures high-reliability service operation through derating and tuning.
In response to the essential need for data security, the KR2266V2 has undergone multiple optimizations in terms of the overall design, protection mechanisms, and feature settings. Through the built-in PFR protection mechanism, firmware can self-repair from malicious attacks. It supports one-click secure data erasure to prevent information leakage and provides support for TPM/TCM trusted modules, ensuring customer data and asset security. With BIOS/BMC chip-level redundancy design, it avoids flash software and hardware damage, ensuring that the entire startup or upgrade process is secure and reliable.
