Description

TECHNICAL FIELD

[0001] The utility model relates to a server structure technical field, concretely relates to a server based on double KP920 module. BACKGROUND

[0002] VPX architecture is a modular computer architecture widely used in military, aerospace and high-performance computing fields, which realizes high-bandwidth data transmission by using high-speed serial buses such as PCIe and Ethernet; its core features are modularity, high reliability and robustness, supporting hot plug and multiple cooling schemes. KP920 module is a high-performance computing module, usually designed based on multi-core processors, suitable for high-density computing scenarios; and double KP920 module refers to integrating two KP920 computing units on a blade to improve single-board computing power, but also brings higher power consumption and cooling challenges. HP (Horizontal Pitch) is the width unit in VPX standard, 1HP≈5.08mm.

[0003] With the improvement of VPX server blade computing performance based on KP920 module, power consumption also increases continuously. Taking an 8-slot 8-piece 5HP server as an example, that is, 8 KP920 modules as all computing modules in the server case, the original 5HP thickness blade cannot meet the cooling demand. To solve this cooling demand, one can use materials with stronger cooling performance, add liquid cooling equipment or multiple micro-channel cooling; the second can replace the original 5HP thickness blade with a 10HP thickness VPX server blade to meet the cooling demand.

[0004] However, the following problems still exist in the current modification method:

[0006] 2) Replacing the traditional 5HP thickness blade with a thicker 10HP thickness blade can improve the cooling effect, but it will reduce the number of blades by half and increase the cost, and the multiplication of thickness often cannot bring the multiplication of computing power, which will indirectly reduce the computing performance of the entire server. For example, the 5HP blade computing power corresponds to x, and the 10HP blade computing power corresponds to 1.8x. The total computing power of the original 8-piece 5HP blade is 8x, and after replacing it with a 10HP blade, it is only 7.2x. INVENTION CONTENTS
