Description
Technical field
The present invention relates to a kind of implementation method of distributed hardware management functions, belong to the network access server field, relate in particular to a kind of with a plurality of hardware management module object distribution on each veneer, realize respectively to hardware monitoring, to the method for hardware operation.
Background technology
" network access server (NAS) technical manual " according to The Ministry of Information Industry of the People's Republic of China, MOII's promulgation, when access server is moved (comprising electrifying startup) in system, need possess following hardware management functions, 1) detects the variation (such as board slot item, plate hot plug, masterslave switchover) of hardware discrete signal in real time, 2) need according to system operation, to hardware carry out specific operation (comprise be provided with host apparatus invalid, system restart is set).Because the basic function that each single plate hardware administration module will be realized is similar, common implementation method is to adopt same module (being specially same target), realize the union of various single plate hardware management functions, and in realizing logic, fully take into account the concrete nuance of each function items on variant veneer.But this method has following shortcoming: 1; specific implementation is very numerous and diverse; the intelligibility of scheme and the readability of program are all poor; because in large-scale complicated system; the function of hardware management module is comparatively complicated; and because the status difference of each veneer in system; make each veneer that bigger difference be arranged on the concrete function of hardware management; and; the another one factor is that master control borad and power board are when realizing redundancy protecting (being masterslave switchover) function; the concrete function that hardware management module realized on host apparatus and the stand-by equipment has again than big-difference (just implementing to write the hardware incapability operation to main with the master control borad of status as having only), and is just bigger specific to the nuance of realizing details.This just causes the steering logic of this module, realization flow very numerous and diverse, finally causes the complexity in Code Design stage, thereby the readability of program and maintainability are reduced greatly, has reduced development efficiency.2, unnecessary complicated of this module and other module interface relation, because occuping the hardware management module of the master control borad of core the driver's seat is one of upper layer software (applications) nucleus module, the hardware discrete message that it will be responsible for collecting simultaneously reports to other correlation module, and the message that receives other relevant module (as: it is invalid that host apparatus is set to implement specific operation to hardware, veneer is set to be restarted), still all hardware information (comprises static information in addition, as slot number, hardware version numbers and multidate information, as: single board state) write unique passage of database, therefore, hardware management module on the master control borad and other module, other subsystem has more interface conjunctionn, but other veneer does not need to possess interface relationship with other module such as the hardware management on the ply-yarn drill, implements comparatively simple.3, bring problems to system performance, the inevitable association of hardware management module on ply-yarn drill some unnecessary or non-existent object types of coming at first as mentioned above, only reside on the master control borad as the database subsystem, its related problem is that one side has produced functional redundancy, has produced a large amount of code redundancies on the other hand, in addition, on the ply-yarn drill administration module will with original non-existent object type interface on the ply-yarn drill, increased communication-cost, increased technical difficulty simultaneously.Secondly, because that the SDRAM (sound attitude random access memory) on the ply-yarn drill and FLASH (nonvolatile memory) capacity are compared with master control borad is much smaller, therefore, the redundancy of program might have serious consequences to ply-yarn drill.
Summary of the invention
The purpose of this invention is to provide a kind of distributed a plurality of objects and realize the method for hardware management on the distributed veneer, can simplified design, reduce the development technique difficulty, can avoid code redundancy again, simultaneously, also improve programmed readability and ease for maintenance.
Method of the present invention is achieved in that it may further comprise the steps: step 1 is obtained this property of single plate, main and standby competition sign, thereby analyzes the functional requirement difference of hardware management module on each veneer; Step 2 is obtained the incidence relation of hardware management module and database subsystem, analyzes that the interface conjunctionn of hardware management module and other module concerns difference on each veneer; Step 3 is obtained the memory size of each veneer, analyzes the difference of hardware management module running environment condition on each veneer; Step 4 according to the functional requirement difference of hardware management module on each veneer, concern the difference of difference, running environment condition with the interface conjunctionn of other module, is divided the hardware management object, and definite one by one needed hardware management object.
Analysis result is in the wherein said step 1, and the hardware management module on the P CPB (Primary Control ProcessBoard, main control board) will realize following function, 1), obtain the main and standby competition sign; 2), the single plate hardware attribute information is provided, as slot number, hardware version information, port information; 3), read veneer hot plug discrete signal; 4), read veneer off-line discrete signal; 5), provide masterslave switchover discrete signal control interface (reading/be provided with); Software reset's function of each veneer 6), is set.B CPB (Backup Control Process Board, slave control board) compares and has lacked the 3rd), 4), 5) function.Hardware management module on the P SPB (Primary Switch Process Board, the main power board of using) is compared and has been lacked the 3rd) function; Hardware management module on the B SPB (Backup Switch Process Board, standby power board) is compared and has been lacked the 3rd), 4), 5) function.Hardware management on the ATM (Asychronous Transfer Mode, this specially refers to the user interface card of asynchronous transfer mode) is compared and has been lacked the 1st), 3), 5) function.Other ply-yarn drill is identical with ATM as the hardware management on the ether card.
Wherein said step 2, the hardware management that has only on the master control borad in all veneers in native system need be related with database subsystem, and database also only resides on the master control borad simultaneously.
Wherein said step 4, analysis result according to above-mentioned steps, because the hardware management that has only on the master control borad in all veneers in native system need be related with database subsystem, for fear of bringing power board and ply-yarn drill with this association, therefore, at first the hardware management on the master control borad is designed to an independent object type, i.e. single plate hardware management type (OBJECTHARDSYSCTRL).And the hardware management on the power board is than having more the 1st on the ply-yarn drill), 5) function, and running environment is difference to some extent also, therefore the hardware management on the power board is designed to another independent object type, i.e. power board hardware management type (OBJECTSPBHARDSYSCTRL); Though as for each ply-yarn drill board type difference, its function items is in full accord, and running environment is also consistent, a therefore unified object type, i.e. the single plate hardware management type (OBJECTBOARDHARDSYSCTRL) of being designed to.
Adopt UML (Unified Modeling Language standard modeling language) design tool to design to above-mentioned three object types, the realization of three class hardware management object types, respectively by residing in master control borad, master control borad hardware management module on power board and each ply-yarn drill (comprising: ATM, Ethernet card), power board hardware management module and ply-yarn drill hardware management module are carried out monitoring management to relevant hardware.
Said master control borad hardware management module to hardware monitoring management flow process mainly is: the basic hardware attribute that at first will obtain this plate comprises slot number, hardware version type, port information, obtain active and standby value of statistical indicant and the flow process below this value decision, if host apparatus, check that each veneer is on the throne, and foundation situation on the throne judges whether minimum system satisfies, if satisfy, then detect whether hot plug or switching request are arranged, if have, also to go shake, if hot plug is arranged really or switches generation, then complain to system; If whether stand-by equipment, it is invalid to detect host apparatus, invalid and still invalid after the past shake as if discovery, then complains to system and trigger this plate to be upgraded to host apparatus.
Said power board hardware management module is to the hardware monitoring management, flow process mainly is: the basic hardware attribute that at first will obtain this plate comprises slot number, hardware version type, port information, obtain active and standby value of statistical indicant and the flow process below this value decision, if host apparatus, detect whether switching request is arranged,, also will go shake if having, if switch generation really, then complain to system; If whether stand-by equipment, it is invalid to detect host apparatus, invalid and still invalid after the past shake as if discovery, then complains to system and trigger this plate to be upgraded to host apparatus.
Said ply-yarn drill hardware management module is to the hardware monitoring management, flow process mainly is: the basic hardware attribute of obtaining this plate comprises slot number, hardware version type, port information, whether detect has the request of hardware off-line, if have, also to go shake, if the request of hardware off-line is arranged really, then complains to system.
Each veneer memory capacity concrete condition is, the capacity of the sound attitude internal memory SDRAM of master control borad is 64M, the capacity of Nonvolatile memory FLASH is 8M, the capacity of the sound attitude internal memory (SDRAM) of power board and the capacity of Nonvolatile memory FLASH are 8M all, and all ply-yarn drills such as ATM155, ETH1000 SDRAM size and FLASH size all are 2M.
