Description
Technical field
The present invention relates to a kind of method of testing of serial I/O SGPIO signal, the method for testing of SGPIO signal on specifically a kind of SAS backboard.
Background technology
SGPIO is the abbreviation of English Serial General Purpose Input/Output, be used for the communication between SAS/SATA control card HBA and the hard disk backboard, HBA obtains the hard disk socket situation on the backboard and sends the hard disk LED condition indicative signal by SGPIO.SGPIO bus and MiniSAS line are placed in the cable, to make things convenient for being connected of HBA and backboard.On the SAS backboard, generally adopt SGPIO signal (by the SFF-8485 agreement) to realize the location of hard disk position, the indication of disk state etc. at present; Parsing to the SFF-8485 agreement is generally realized by the programmable logic device (PLD) that is integrated on the SAS backboard, after programmable logic device (PLD) SFF-8485 agreement is resolved, by LED or LCD display device the state of each hard disk is indicated.Current test for SFF-8485 protocol analysis on the SAS backboard of mass production, the main employing: with the SAS backboard connecting system of hard disk full configuration, after powering on, utilize the system software of SAS card collocation, test the state of each hard disk one by one, this mode has the following disadvantages: the one, and test speed is slow, after all needing system to power on for each SAS backboard, utilize software interface, each hard disk position is tested one by one, bring very big inconvenience for like this volume production of system; The 2nd, with the SAS backboard connecting system of hard disk full configuration, long-term test to all impacting hard disk performance, service time, causes the waste of hard disk resource, simultaneously each hard disk is inserted or extracts backboard, all greatly has influence on testing efficiency with stable; The 3rd, in the early stage of SAS back plate design, whether need debug programmable logic device (PLD) repeatedly correct to the parsing of SFF-8485 agreement, need constantly restart server system, the performance of the server system that participates in debugging is produced greater impact, also cause the unnecessary wasting of resources; Therefore the method for testing that needs SGPIO signal on a kind of new SAS backboard, substitute current efficient lower, cause the test mode of the wasting of resources simultaneously.
Summary of the invention
Technical assignment of the present invention is to solve the deficiencies in the prior art, and the method for testing of SGPIO signal on a kind of SAS backboard is provided.
Technical scheme of the present invention realizes that in the following manner hardware environment comprises: simulation SGPIO signal data takes place and processing unit; Disk state user-defined visual unit; The mini sas interface of standard; Wherein, simulation SGPIO signal data takes place to be responsible for producing the signal form that meets the SFF-8485 agreement that needs with processing unit, simultaneously signal frequency is realized dividing the free conversion and control in cycle, to test the sas backboard to the protocol analysis adaptive faculty in the SFF-8485 agreement specified signal frequency range; Disk state user-defined visual unit is shown in the hard disk imagery on the visual LCD Touch Screen, and by crawl touch to screen, location, the hard disk failure information of hard disk is sent in simulation, and realization is manual or the selection of automatic test pattern, under the manual mode, point touches corresponding hard disk position on the LCD Touch Screen, and gives the indication operation that does well; Under the automatic mode, the test macro of SAS backboard SGPIO signal will be from hard disk sequence number extreme lower position on the SAS backboard, finish hard disk sequence number extreme higher position to the SAS backboard, circulation is sent location, the hard disk failure information of each hard disk that meets SFF-8485 protocol signal form and is given the SAS backboard, the tester only need estimate the situation of flashing and the order of hard disk pilot lamp on the SAS backboard, judges that test sas backboard is to SFF-8485 protocol analysis adaptive faculty;
Its concrete testing procedure is as follows:
1) connect MINI SAS cable, this cable one termination is gone into SAS backboard to be measured, the other end inserts the test macro of SAS backboard SGPIO signal, and SAS backboard to be measured need not to connect hard disk; Simultaneously with the test macro of SAS backboard SGPIO signal, SAS backboard to be measured energising;
2) set test pattern on visualization, test pattern is divided into manual mode and automatic mode: under the manual mode, need one one hard disk positions of touching corresponding demonstration on the visualization, and indication is operated according to state; Under the automatic mode, the test macro of SAS backboard SGPIO signal will be from hard disk sequence number extreme lower position on the SAS backboard, finish hard disk sequence number extreme higher position to the SAS backboard, circulation is sent information such as the location, hard disk failure of each hard disk and is given the SAS backboard, the tester only need estimate the situation of flashing and the order of hard disk pilot lamp on the SAS backboard, can judge that testing SA S backboard is to SFF-8485 protocol analysis adaptive faculty;
3) frequency or the frequency range of setting SGPIO signal on visualization, if set the frequency range of SGPIO signal, then the test macro of SAS backboard SGPIO signal can increase from the low frequency value to the high frequency value automatically, with full test SAS backboard to the protocol analysis adaptive faculty in the SFF-8485 agreement specified signal frequency range;
4) configure test pattern and produce the frequency of test signal after, visualization shows the virtual hard disk location drawing, and the current SAS backboard hard disk port status of testing shown, the tester confirms that according to range estimation the state of LED light of the hard disk port position on the SAS backboard is whether consistent with the information that visualization provides, if both information unanimities, then the SAS backboard is normal to the SFF-8485 protocol analysis.
Described visualization is the LCD touch-screen.
Described SAS backboard hard disk port status comprises hard disk locating information, the hard disk failure information that meets the SFF-8485 agreement.
The beneficial effect of the inventive method is:
The method of testing of SGPIO signal on the SAS backboard of the present invention, have characteristics such as graphical, flexible compatibility and extended attribute, after the system of each SAS backboard powered on, test speed was fast, visualization directly shows all disk states, benefits the volume production of system; Test duration is short, can not impact hard disk performance, service time, reduces the waste of hard disk resource, has guaranteed that testing efficiency is with stable; On the basis that does not change existing server S GPIO signal application framework, directly interconnected by SFF-8485 protocol bus and test macro, with the systemic-function refinement, finish by different functional units respectively, can dispose flexibly, reduce the complexity of system management; Need not to take under the situation of server and hard disk resource, greatly simplified testing process, avoid the repeated switching operation that plugs server under operation and the traditional test mode repeatedly of hard disk, realized graphical, the interfaceization of SGPIO signal testing flow process.
