What please note is, the type of the initial equipment card 1 of universal error detecting auxiliary device of the present invention and target device card 2 above-mentioned each interface and used element (for example: balanced device 14, signal improve element 160, multiplexer 260, switch switching device 26 and port and select element 29 etc.) only is the example that universal error detecting auxiliary device of the present invention is lifted, but does not therefore limit claim of the present invention; In fact, universal error detecting auxiliary device of the present invention can adopt other agreement or all types of interface and elements according to the actual requirements, and can increase the quantity of interface and element.
Please refer to Fig. 5, be the application example of explanation according to universal error detecting auxiliary device of the present invention, it is interior to carry out online debug with convenient general storage facilities of insertion such as disk array (RAID) equipment that wherein initial equipment card 1 can be a kind of clamp pattern, promptly diagnoses the signal of this storage facilities internal hard drive interface to have no abnormal.Before initial equipment card 1 inserts storage facilities, backboard (Midplane) 41, several SAS/SATA hard disks 43 and cabinet 42 in the middle of general storage facilities promptly comprises one, and these SAS/SATA hard disk 43 parallel stacks are arranged and electrically connect (not shown)s via Connection Element (as the SAS connector) and backboard 41 respectively, and backboard 41 and hard disk 43 are arranged in the cabinet 42.
In order to carry out debug, for example can't discern or can not correctly discern a wherein a certain hard disk 43 when main frame sees through backboard 41, can earlier this hard disk 43 be extracted in cabinet 42, again initial equipment card 1 of the present invention is inserted in the storage facilities, the corresponding interface of backboard 41 is docked to be used as initial equipment with initial equipment interface 11, the corresponding interface of this hard disk 43 docks to be used as target device with the target device interface of target device card 2, in the present embodiment, hard disk 43 docks with the first target device interface 22.The first target external interface 21 of the initial external interface 12 of initial equipment card 1, target device card 2 is coupled to the input end 31 and the output terminal 32 of SAS testing apparatus 3 respectively by cable.
By above connection, information flow is directed between the input end 31 and output terminal 32 of backboard 41 and SAS proving installation 3 via initial equipment interface 11, inband signaling channel 13 and initial external interface 12, and/or information flow is directed between the input end 31 and output terminal 32 of hard disk 43 and SAS proving installation 3 via the first target device interface 22, inband signaling channel 251 and the first target external interface 21.By turning to of above information flow, can make the diagnosis of internal signal for 3 pairs of these storage facilitiess of SAS testing apparatus.
Please refer to Fig. 6, disconnect being connected of 32 of the input end 31 of the first target external interface 21 and SAS testing apparatus 3 of initial external interface 12, target device card 2 of initial equipment card 1 and output terminals, connect the first target external interface 21 of the initial external interface 12 of initial equipment card 1 in target device card 2, make straight-through connection of 41 of hard disk 43 and backboards, realize the direct communication of the signal of 43 of backboard 41 and hard disks.
If carry on the initial equipment interface 11 or the first target device interface 22 some out-of-band-signal for example backboard send to the control signal of Hard disk error cresset and to the control signal of hard disk energising or outage, the hard disk that hard disk sends inserts signal etc., connect the first initial external interface 21 of the out-of-band-signal interface 15 of initial equipment card 1 in target device card 2, out-of-band-signal on the initial equipment interface 11 inputs to out-of-band-signal interface 15 via out-of-band-signal channel 16, transfer to the first target external interface 21 via connection cable (not label), obtain these out-of-band-signal after by out-of-band-signal channel 261 at the first target external interface 21, multiplexer 260, out-of-band-signal channel 262 data transmissions are given hard disk 43, finish the out-of-band-signal transfer function.The direction of the out-of-band-signal on the transmission direction of the out-of-band-signal on the initial equipment interface 11 and the first target device interface 22 is opposite.Like this, these out-of-band-signal directly transfer to hard disk 31 via universal error detecting auxiliary device of the present invention, and needn't pass through SAS proving installation 3, thereby can avoid the problem that has out-of-band-signal to lose as prior art, so the present invention also can possess the integrality of systemic-function when carrying out the debug program.In addition, needs according to the operator, control via switch switching device 26, can control out-of-band-signal that backboard 41 or hard disk 43 send finishes transmission or covers backboard 41 or out-of-band-signal that hard disk 43 sends, even direct virtual backboard or hard disk send these out-of-band-signal, therefore can realize the function of the function of transmission control of these out-of-band-signal and change, reconstruction, these out-of-band-signal of emulation, so universal error detecting auxiliary device of the present invention has preferable debug dirigibility.Universal error detecting auxiliary device of the present invention can be set up more a plurality of initial equipment cards 1 or target device card 2, debug when being used between a target device and a plurality of initial equipment, debug when perhaps being used between a plurality of target devices and the initial equipment, can also be used for the debug between a plurality of target devices and a plurality of initial equipment, principle is the same, does not give unnecessary details.
In above-mentioned application example, the length of the clamp 10 of initial equipment card 1 is slightly larger than or equals the length of hard disk 43, after inserting in the cabinet 42, the initial external interface 12 of this initial equipment card 1 and out-of-band-signal interface 15 are exposed to outside the cabinet 42, in order to being connected with miscellaneous equipment.Because initial equipment card 1 is the environment that is in cabinet 42, so can directly provide power supply by backboard 41, the power supply terminal that just utilizes the SAS connector on the backboard 41 provides power supply via the power supply terminal of the correspondence of initial equipment interface 11 to initial equipment card 1.Initial equipment card 1 also can be provided with a supply socket (not shown), and in order to be connected to externally fed equipment (as the 220V power supply) so that universal error detecting auxiliary device is powered, principle is not given unnecessary details with the supply socket of target device card 2.
Please refer to Fig. 7, is the application example that universal error detecting auxiliary device of the present invention is used for the debug of the hard disk 43 in the storage facilities itself.When the circuit of 41 of hard disk 43 and backboards well and only is a hard disk 43 when itself going wrong, universal error detecting auxiliary device of the present invention can connect 6 pairs of hard disks of a SAS/SATA information generator 43 and carry out debug.The first target device interface 22 of the target device card 2 of universal error detecting auxiliary device of the present invention docks with the corresponding interface of hard disk 43, the first target external interface 21 is coupled to SAS/SATA information generator 6, information is exchanged between SAS/SATA information generator 6 and hard disk 43, SAS/SATA information generator 6 sends test signal, according to the response of hard disk 43, the problem that judgement and debug hard disk 43 occur.
Universal error detecting auxiliary device of the present invention adopts the two clips design, design initial equipment card 1 and target device card 2 respectively, the complex circuit designs degree is low, structural member is realized easily, applied widely, the firmware development cost is low, reduced total cost, and have and connect the steadiness height, execute-in-place is convenient and plug advantages such as easy.
