Description of the Invention: [Technical Field] The present invention relates to a general-purpose debugging assistance device, and more particularly to a general-purpose SAS interface debugging assistance device. [Prior Art] Serial Attached SCSI (SAS) is a hard disk interface technology that can transmit and support dual-speed and is compatible with the s a/saTA (serial port) interface. Expanding the connection function through the expander (Expander), it can be applied not only to the server, but also to various storage devices such as a disk array (RAID). With the continuous upgrade of the SAS protocol version and the increase of the transmission speed, the requirements for debugging (Debug) are getting higher and higher, but there is no effective and simple auxiliary device on the market to help the SAS interface to communicate. Solve the problem of signal errors that may be encountered in the development and operation of electronic products. In the current SAS interface product development and post-operation maintenance process, the traditional debugging method is to connect the SAS Protocol Analyzer (SAS Protocol Analyzer) such as SAS Tracker (SAS TRACER) directly to the starting device by using multiple cables. (Initiator) and the target device (Target), and perform data packet capture, protocol decoding, statistical analysis and other debugging functions. However, such a conventional debugging method using a simple cable connection has the following disadvantages: 1. The target device must be exposed to a place where the connection cable can be plugged and unplugged. When the connection interface of the target device is in the deep inner part of the chassis or the rack in the upper part, it is extremely inconvenient for the operator to plug and unplug the cable in the narrow chassis space or on the upper frame, and the line is very inconvenient. The connection stability is poor, and the cable is prone to problems such as looseness of the cable; the longer the length of the connection cable is, the more the signal is attenuated; 5 201001158 2. Each time the topology of the entire system is changed, the topology needs to be inserted. Pulling cables or moving the instrument may cause unnecessary damage. 3. In some designs, the SAS interface will need to carry some Out-of-Band Signaling, such as control of the hard disk error light signal. Signal. If a conventional debugging method using cable connections is used, these FSB signals will be lost after passing the protocol analyzer, which will destroy the integrity of the system function.
鑒於以上缺點’尤其是於當前要求訊號傳輸速率達3G和6G 之情形下’藉由線纜連接之習知偵錯方法難以保證訊號傳輸之可 靠性。 故有必要提供一種新穎的偵錯輔助設備，以克服藉由線纜 連接之習知彳貞錯方法的缺點。 【發明内容】 本發明夕—+ 主要目的在於提供一種通用偵錯輔助裝置，其可 達成多種連接需求。 本發明之另— 避免丟失外頻訊號 本發明之又一 減少線纜之使用、 拔容易。In view of the above drawbacks, especially in the case where the current signal transmission rate is required to be 3G and 6G, the conventional debugging method by cable connection is difficult to ensure the reliability of signal transmission. It is therefore necessary to provide a novel debug aid to overcome the shortcomings of the conventional method of connecting by cable. SUMMARY OF THE INVENTION The present invention is to provide a universal debugging assistance device that can achieve various connection requirements. Another aspect of the present invention is to avoid loss of external frequency signals. Another aspect of the present invention is to reduce the use and ease of cable extraction.

The above-mentioned contents of the present invention can be more clearly understood. The following description of the present invention will be described in detail with reference to the accompanying drawings. The universal debt error assisting device i of the preferred embodiment mainly comprises: a card board (not shown), a first SAS expander (Ε-〇 131, a second SAS expander 132 and a first MS expander i3i) 7 201001158 is connected to a plurality of external interfaces and a control interface 27. The plurality of external interfaces, including the first interface 2, the second interface 22, the third interface 23, the fourth interface %, the fifth interface 25, and the sixth interface 26 In this embodiment, the card board is configured to carry the first expander 131 and the second expander 132, the plurality of external interfaces, and the control interface 27. The switch board is provided with a conductive line (not shown). For electrically connecting the first expander ΐ3ΐ and the second expander 132, the plurality of external interfaces, and the control interface 27. Of course, the first expander 131 and the second expander 132, the plurality of external interfaces, and the Electrical connection between control interfaces π It can also be achieved by wires. The first interface 21 has a 29-terminal sas socket connector for connecting the target device. The second interface 22 has a 29-terminal sas plug connector for connecting the starting device. The aforementioned third interface 23, fourth Each interface of the interface %, the fifth "face 25 and the sixth interface 26 includes four industry standard MiniSAS connectors, wherein the third interface 23 is connected to the initiating device, and the fourth interface 24 is used to connect the target. The device 'and the fifth interface 25 and the sixth interface % are used to connect to the SAS test device, such as a SAS protocol analyzer (Analyzer) or a SAS information generator (Generator) or a SAS information interference transmitter (Jammer), etc. The first interface 21, the second interface 23 and the fifth interface 25 are respectively connected to the second S AS expander 132, and the second interface 22, the fourth interface 24, and the sixth interface 20 are respectively connected to the first SAS expander 131. The first SAS expander 131 has two general-purpose I/O port 'GPI〇's, wherein a general-purpose input/output interface is connected to the first interface 21' and another general-purpose input/output interface is connected. The second interface 22 can transmit control signals between the devices connected to the first interface 21 and the second interface 22. The first SAS expander 131 is configured to capture and transmit the drive control signals or transmit via the external frequency signals 172, 174. External frequency control signal, etc. (detailed later). 8 201001158 In this embodiment, the control interface 27 is an RS232 type connector, one end of which is used for external control device 271 (such as a personal computer or an external control module). The connection is to provide a user error detection interface, and the other end of the control interface 27 is connected to the first SAS expander 131 and the second sas extension 132 via the toggle switch element 270. Thereby, the control device 271 can switch between the first SAS expander 131 or the second SAS expander 132 via the switch element 270 as needed to selectively use the controller of the first SAS expander or the second SAS expander. The program can control the connection state between the internal circuit of the general error debugging auxiliary device 1 and the external interface, including the link switching, the connection topology of the flexible configuration data, and the like (described later in detail). It should be noted that the types of the expanders, the protocols and the number of interfaces, the external interfaces, and the types of control interfaces are only examples of the universal debug assist device 1 of the present invention, but do not limit the patent of the present invention. Scope; In essence, the universal debugging auxiliary device 1 of the present invention can adopt other protocols or various types of expanders according to actual needs (for example, when used as a fiber-optic device for debugging, the fiber expander should be used) and various types of external interfaces and control interfaces. And can increase the number of external interfaces, control interfaces, and expanders. In other embodiments, the control device 271 can also be a simple switchover device (not shown) that is not directly connected via the control interface 27, but is directly disposed on the card in the general-purpose debug auxiliary device. The first SAS expander 131 and/or the second SAS expander 132 are directly connected to control the connection state between the internal circuit of the universal debugging auxiliary device 1 and the external interface. The universal debugging aid 1 can also have the above two control devices, that is, the control device 271 connected via the control interface 27 and the outside of the universal debugging aid 1 (such as the surface of the card) and directly connected to the first device. The SAS expander 131 and/or the control device of the second SAS expander 132 'the two control devices can implement the same function, and the operator can 9 201001158 to select which control device to use according to the actual situation, for example, when General Blessing When the auxiliary device 1 is in the upper frame, the control device 27〇 connected via the control interface 27 can be used. When the universal debugging assist device 1 is in a position accessible to the operator, the setting is used in the general detection. The control device external to the wrong auxiliary device 1 is more convenient. Of course, the two control devices can also control different connection states to achieve different functions. Please refer to FIG. 2 and FIG. 3A for explaining an application example of the universal debt assisting device 1 according to the present invention, that is, the universal debugging assisting device can be a card type to facilitate insertion into a general storage device such as a disk array ( In the RAID) device, the connection debugging is performed to diagnose whether the signal of the internal hard disk interface of the storage device is abnormal. Before the universal debt auxiliary device 1 is inserted into the storage device, the general storage device includes a midplane (Midplane) 33, a plurality of SAS/SATA hard disks 31, and a chassis, and the SAS/SATA hard disks 31 are parallel. The stacking is arranged and electrically connected to the backboard 33 via a connecting component (such as a = terminal SAS connector) (not shown), and the backplane 3 disc 31 is disposed in the chassis 35. In order to perform debugging, for example, when the host cannot identify or unidentify a certain hard disk 31 through the backplane, the hard disk 31 can be pulled out from the shop first, and then the universal ship auxiliary device of the present invention is used. i is inserted into the storage device such that the corresponding interface of the hard interface is interfaced with the first interface 21 of the universal debugging aid 1 to serve as the first target device, and the corresponding interface of the backplane 33 is docked with the second interface 22 to The first device's fifth interface 25 and the sixth interface % are respectively connected to a sas test: the input of the standby 4 (such as the protocol analyzer/information interference transmitter) and the wheel-out interface control interface 27 are coupled to the control. Device 271. To perform the debugging operation, the operator forces the backplane 33 to input from the external control device via the connection of the four 201001158 internal frequency signal channels 152 between the woven first SAS expander 131 and the second Μ expander 132. The information flow of the first SAS expander 131 is turned as shown in FIG. 2, and the information flow is directed to the input and output ends of the backplane 33 and the SAS testing device 4 via the second interface 22, the signal channel 154 and the sixth interface 26. The information flow between the 'and/or forced hard disk 31 input to the second SAS expander 132 is turned as shown in FIG. 2, and the information flow is directed to the hard disk via the first interface 21, the signal channel 156, and the fifth interface 25. 31 is between the input and output of the SAS test set 4. With the above information flow steering, the SAS test equipment 4 can make an internal signal diagnosis for the storage device. On the contrary, the operator can also close the signal channel of the first SAS expander 131 and the second SAS expander 132 to the SAS test device 4 via the control device 271, and reopen the connection between the first sas expander 131 and the second SAS expander 132. The connection of the four internal frequency signal channels 152 achieves a direct connection between the hard disk and the backplane to change the external frequency signal (described in detail later). Therefore, the present invention can achieve the function of a programmable connection topology, and can reduce the use of cables, increase the stability of signal connection, and facilitate on-site operation. In this application example, since the universal debugging assisting device 1 is in the environment of the chassis 35, the power can be directly supplied from the backboard 33, that is, the power terminal of the 29-terminal SAS connector on the backplane 3 3 is used. The corresponding power supply terminal of interface 2 provides power to the universal debug assist device of the present invention. In this application example, if the second interface 22 or the interface 21 carries a control signal such as, for example, a hard disk error signal issued by the backplane, and a control for powering on or off the power of one disk, the hard disk is issued. The hard disk is inserted into the signal, and the external frequency signal on the second interface 22 is transmitted through the first external frequency signal channel ο] i SAS expander 131. After the first SAS breaks into the first row, the pole A, ° and some of the external frequency signals go in, and the second external frequency signal channel 174 transmits the data to the hard disk transmission function. The direction of the external frequency signal on the first interface 21 is opposite to the direction of the external frequency signal on the surface 22. If yes, these external frequency signals are directly transmitted to the hard disk 31 via the universal debugging aid 1 of the present invention, without having to pass the SAS testing device 4, so that the problem of loss of the external frequency signal as in the prior art can be avoided, so the present invention The integrity of the system function can be preserved while performing the debugging process. In addition, according to the needs of the operator, the first SAS expander 131 can transmit the external frequency signal through the backplane or the hard disk, or even directly send the external frequency signal to the virtual backplane or the hard disk, so that the external SAS expander 131 can realize The function of changing, reconstructing, and simulating these EMF signals is thus 'the general debug aid 1 of the present invention has better debugging flexibility. For example, when we need to debug the backplane, we can even test the backplane without actually accessing the hard disk' and just send a virtual FSB signal (such as a hard disk insertion signal) from the first SAS expander m. Whether it can respond normally, the same can be used to debug the hard disk 31 using the virtual backplane signal. The universal debugging auxiliary device 1 of the present invention can add more external interfaces for detecting between a target device and multiple initial screams. It can also be used between multiple target devices and one starting device. The debugging can also be used for debugging between multiple target devices and multiple starting devices.
