Description

Veneer is inserted in ATCA machine frame system, construction method and back
Technical field
The present invention relates to the communications field, after a kind of ATCA (Advanced Telecom ComputingArchitecture, advanced telecom computing platform) machine frame system and construction method and ATCA machine frame system, plug in veneer.
Background technology
Along with the development of telecommunication service, telecom operators pay close attention to flexibility, opening, extensibility and the professional stability of telecommunication platform all the more.So PICMG (PCI Industrial Computer Manufacturers Group; PCI industrial computer manufacturing tissue) related specifications of the open hardware platform of ATCA has been proposed; Be called PICMG 3.X standard, this standard specifies the mechanical framework of ATCA, electric power system, heat abstractor, switching fabric and interconnected, system management, back board structure etc.
According to PICMG 3.X standard; In the system of ATCA framework; Each machine frame is equipped with two CMM (ChassisManagement Module, Shelf management module), is independent veneer; Directly be inserted on the ATCA backboard; Two CMM are active and standby each other, as shown in Figure 1, and each CMM can manage all veneers or FRU (the Field Replaceable Unit in the machine frame separately; But the field replacement unit); All need realize the function of IPMC (Intelligent Platform ManagementController, intelligent platform management controller) simultaneously in each veneer, IPMC mainly accomplishes supervision, control and the management of various key hardware resources on ATCA veneer or other machine frame assemblies; Effective payload part state-detection, veneer temperature and voltage detecting, hot plug management, the FRU information that comprises veneer or module is obtained, alarm management, power management, reset mode, transducer and incident management, log management, E-Keying (electronic switch) management etc.; To accomplish AMC (Advanced Mezzanine Card, senior sandwich sub card) subcard hardware address, temperature, voltage simultaneously, reset, the management and the logout of hot plug and alarm indicator etc., through IPMB (the Intelligent Platform Management Bus of two redundancies; Intelligent Platform Management Bus) bus is communicated by letter with CMM, gives CMM variety of event and information reporting and accepts management and the control of CMM.
Also stipulate in the PICMG 3.X standard, regional by the preceding slotting switching board (HUB BOARD) of ATCA machine frame system at backboard ZONE2, to each Node Board (NODE BOARD) two three pairs of redundant differential clocks are provided, to satisfy the system synchronization demand of strictness.
Along with the field of ATCA system applies more and more widely, the exchange capacity of ATCA system, traffic handing capacity, medium access capability all need to promote.And in the ATCA machine frame system of PICMG 3.X regulation, as shown in Figure 2,14 groove position ATCA machine frames, 7,8 two groove positions are configured to switching board (HUB BOARD), and all the other 12 groove positions are Node Board (NODEBOARD); Switching board BASE Interface (basic interface) maximum only can provide 15 passages; Fabric Interface (Fabric Interface) maximum also only can provide 15 passages; Again because switching board has taken the groove position of 2 Node Boards, the traffic handing capacity of system is restricted simultaneously.In addition, employing of back plug-in card and preceding plug in veneer mainly realize expansions such as preceding slotting single board interface, thereby the medium access capability are not enough to inserting mode in this system.
Therefore; Need improve the ATCA machine frame system architecture of PICMG 3.X standard; Most importantly insert server blade before keeping and meet PICMG 3.X standard, veneer is inserted in the back directly be connected with backboard, and the medium access capability of the plug in veneer in expansion back and exchange capacity etc.
