Method for designing lU system based on MicroTCA standard

Abstract

The invention provides a 1U system design method based on MicroTCA standard, wherein a backboard is in horizontal arrangement and provides the physical connection based on the high speed serial technology between the high class interlayer card, and backboard is equipped with a extra strong pipe switching module, a enlargement module controller and an x86 COM-EXPRESS module. The project of the invention solves the problem of the system performance and the price under the premise which perfectly accords with the MicroTCA module interconnecting criterion with good applying foreground.

Description

technical field [0001] The invention relates to a 1U system design method based on the MicroTCA standard. Background technique [0002] MicroTCA is a medium and low-cost equipment specification defined by the international organization PICMG on the basis of ATCA (Advanced Telecom and Computing Architecture) defined by PICMG 3.0. It is one of the most important industrial standards for the new generation of telecommunications and computing equipment. In the MicroTCA standard, there are 5 key modules. The most important module is Advanced Mezzanine Card-AMC (Advanced MezzanineCard), which is a modular hardware board unit that can be upgraded on site. The second is the backplane, which provides the physical connection between AMC cards based on high-speed serial technology. Then there is the MicroTCA bearer hub-MCH (MicroTCA Carrier Hub), which is a special AMC that provides high-speed data and control information exchange between AMCs. The MCH is integrated with a general sw...

Problems solved by technology

On the other hand, the current mainstream equipment used by enterprises is based on PC server technology, and the system height of most logarithms is 1U, mainly because the Internet data center charges according to the height of the equipment, and the operating price increases for every 1U increase in the height of the equipment. 1 times

But in MicroTCA R1.0, there is no definition of 1U size equipment

The main reason is that, under the limitation of 1U height, AMC must be changed from a vertical insertion system to a horizontal insertion system, which brings corresponding changes in backplane design, power module and cooling unit design, and standard units cannot be reused

Due to the limitation of the width at 19 o'clock, the 1U system can only accommodate 4 AMCs, and the expansion capability is limited

[0006] In summary, the 1U size MicroTCA system has the above shortcomings, and the research on the design method of the 1U system based on the MicroTCA standard will be a major technical issue worth studying.
