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

A kind of 1U design method based on the MicroTCA standard

Technical field

The present invention relates to a kind of 1U design method based on the MicroTCA standard.

Background technology

MicroTCA is the middle low-cost device standard of the PICMG of international organization definition on ATCA (the AdvancedTelecom and Computing Architecture) basis of PICMG 3.0 definition, is one of telecommunications of new generation and the most important industrial standard of computing equipment.In the MicroTCA standard, there are 5 key modules.Most important module is advanced mezzanine card-AMC (Advanced MezzanineCard), be can field upgrade modularized hardware integrated circuit board unit.Next is a backboard, and the physical connection based on the high speed serialization technology is provided between the AMC card.The MicroTCA of being carrying hub-MCH (MicroTCA Carrier Hub) is arranged again, be a kind of special AMC, for the data at a high speed and the exchange of control information are provided between each AMC, on MCH, be integrated with general Switching Module (Common Option Fabric), the MCMC of extra heavy pipe Switching Module (Fatpipe Fabric) and responsible AMC platform management.In addition also have cooling unit (Cooling Unit) that the wind-cooling heat dissipating of system is provided, power module provides the power supply of system to supply with and management.

MicroTCA is not only towards telecommunications and computing equipment market, also because its low cost, high-performance and flexibility can be supported the application of medical treatment, industry control and military aspect future.The hardware formats of several systems has been proposed in MicroTCA R1.0 version.System's machine frame of MicroTCA has various selection, can support the AMC of varying number, and the kind of AMC can be multifarious, different functions is provided but all meets the interconnected and management regulation of module of MicroTCA regulation, thereby modular Hardware Design becomes possibility.Fig. 1 is that the typical case also is a kind of 19 o'clock 4U size MicroTCA system design that meets the carrier class application of single frame capacity maximum the most.

Power module, cooling unit, MicroTCA carrying hub important in this system have all been realized 1: 1 Redundancy Design, it is same functional unit repeated configuration in system, one be master unit another be auxiliary unit, master unit plays a role at ordinary times, auxiliary unit is in off-line state, only accepts system mode and upgrades.When the situation that master unit lost efficacy took place, auxiliary unit can Upgrade Now and take over system into master unit, has improved the reliability of system greatly.

Because the original idea of MicoTCA is telecommunications and computing equipment market towards low and middle-end, this wherein the enterprise market can be to occupy very big part.Can realize the switch of enterprise-level, safety means, video conference and watch-dog, memory device and VoIP switch device easily based on MicroTCA framework and AMC unit.On the other hand, the main flow equipment of enterprise's application at present is based on the PC server technology, and the system height of exhausted big logarithm all is 1U, mainly because Internet Data Center is to charge according to device height, and the height of the every increase of equipment 1U, 1 times of operation price increase.But in MicroTCA R1.0, do not define the equipment of 1U size.Its main cause be because, under the restriction of 1U height, AMC must change horizontal insertion system into from vertical insertion system, has correspondingly brought the design of back plate design, power module and cooling unit to change, standard cell can not be reused.Because the restriction of 19 o'clock width, the system of 1U can only hold 4 AMC, and extended capability is limited.

To sum up, there is above-mentioned shortcoming in the MicroTCA system of 1U size, based on the research of the 1U design method of MicroTCA standard, will be a key technical problem that is worth research.

Summary of the invention

The purpose of this invention is to provide a kind of 1U design method, interconnect under the prerequisite of standard meeting the MicroTCA module fully, solved the problem of systematic function and price based on the MicroTCA standard.

Purpose of the present invention is achieved through the following technical solutions:

A kind of 1U design method based on the MicroTCA standard, it is characterized in that: backboard is and is horizontally disposed with, backboard provides between the advanced mezzanine card based on the physical connection of high speed serialization technology, and extra heavy pipe Switching Module, enhancement mode block controller and x86COM-EXPRESS module are arranged on the backboard.

The outstanding substantive distinguishing features and the obvious improvement of technical solution of the present invention is mainly reflected in:

All AMC that meet the AMC standard definition can be inserted into native system, its IPMI, it goes without doing any change of Common Option Fabric and Fatpipe Fabric interface.Realized and modular system design flexibly.Power module can use the ATX power supply of PC standard, and does not need to use the MicroTCA power source special, has reduced system cost.Cooling unit uses the fan wall of PC server standard, and does not need the cooling unit that uses MicroTCA proprietary, has reduced system cost.On backboard, realize the function of Fatpipe Fabric, can support Serial Rapid IO and PCI-EXPRESS switching technology simultaneously, do not needed to use special Fatpipe Fabric AMC, greatly reduced system cost.The controlled function that business equipment much needs x86CPU to provide generally needs to use x86CPU AMC, and the present invention can save an AMC groove position in the integrated x86CPU functional module of backboard, compares x86AMC simultaneously, and cost reduces by 50～60%.The Machine Design of the 1U machine box for server of use standard and ATCA carry the AMC connector that card uses, and greatly reduce system cost.

Description of drawings

Below in conjunction with accompanying drawing technical solution of the present invention is described further:
