Description
本發明係關於測試裝置，尤指一種SAS介面測試裝置。 The present invention relates to test devices, and more particularly to a SAS interface test device.
SAS(Serial Attached SCSI)即串列連接SCSI(Small computer systems interface，小型電腦系統介面)，是新一代之SCSI技術，其是在並行SCSI之後開發出來之全新介面技術。SAS介面設計是為了改善存儲系統之效能、可用性和擴充性。 SAS (Serial Attached SCSI) is a small-scale computer system interface (SCSI). It is a new generation of SCSI technology, which is a new interface technology developed after parallel SCSI. The SAS interface is designed to improve the performance, availability, and scalability of storage systems.
目前，主機板上通常會設置複數SAS介面，當測試該等SAS介面之時，一般做法是測試人員手動將複數SAS硬碟分別連接到該等SAS介面上，再將主機板測試儀與主機板相連，然後再執行相應之測試程式來達到測試SAS介面功能之目的。由於SAS硬碟價格較高，若同時使用較多SAS硬碟必然會造成測試成本過高，但若只使用一個SAS硬碟進行測試，測試人員則需每測試完一個SAS介面後又要重新插拔SAS硬碟，並且還要重新啟動測試程式，這樣則會大大浪費測試時間。 At present, a plurality of SAS interfaces are usually set on the motherboard. When testing the SAS interfaces, the tester manually connects the plurality of SAS hard disks to the SAS interfaces, and then the motherboard tester and the motherboard. Connected, and then execute the corresponding test program to achieve the purpose of testing the SAS interface function. Due to the high price of SAS hard disk, if the SAS hard disk is used at the same time, the test cost will be too high. However, if only one SAS hard disk is used for testing, the tester needs to re-insert after testing one SAS interface. Pull the SAS hard drive and restart the test program, which will waste a lot of test time.
鑒於以上內容，有必要提供一種SAS介面測試裝置，僅需一個SAS硬碟即可同時測試複數SAS介面，且省時省力。 In view of the above, it is necessary to provide a SAS interface test device that can test multiple SAS interfaces simultaneously with only one SAS hard disk, saving time and effort.
一種SAS介面測試裝置，包括複數SAS介面連接器、一SAS硬碟介面連接器及一多路選擇開關，該等SAS介面連接器上之電源引腳分別與該多路選擇開關上之複數開關觸點一一相連，該多路選擇開關上之主端子與該SAS硬碟 介面連接器上之對應電源引腳相連，該等SAS介面連接器上之其他引腳均與該SAS硬碟介面連接器上之對應引腳相連。 A SAS interface test device includes a plurality of SAS interface connectors, a SAS hard disk interface connector, and a multi-way selection switch, wherein the power pins on the SAS interface connectors are respectively touched by the plurality of switches on the multi-way selection switch Connected one by one, the main terminal on the multiplexer and the SAS hard disk The corresponding power pins on the interface connector are connected, and the other pins on the SAS interface connectors are connected to corresponding pins on the SAS hard disk interface connector.
相較習知技術，將該等SAS介面連接器連接複數待測SAS介面，該SAS硬碟介面連接器連接一個SAS硬碟後，該SAS介面測試裝置利用該多路選擇開關對該等SAS介面連接器與該SAS硬碟介面連接器之間進行切換，而不需人力進行手動插拔SAS硬碟之動作，且僅需一個SAS硬碟即可完成對複數SAS介面之測試，節省了成本，也極大地方便了測試人員，提高了測試效率。 Compared with the prior art, the SAS interface connector is connected to a plurality of SAS interfaces to be tested. After the SAS hard disk interface connector is connected to a SAS hard disk, the SAS interface test device uses the multiple selection switch to connect the SAS interfaces. The switch is switched between the connector and the SAS hard disk interface connector, and the manual SAS hard disk is manually inserted and removed, and only one SAS hard disk is required to complete the test of the plurality of SAS interfaces, thereby saving costs. It also greatly facilitates the testers and improves the test efficiency.
請參考圖1，本發明SAS介面測試裝置10用於測試主機板上之SAS介面，其較佳實施方式包括八個SAS介面連接器12、一SAS硬碟介面連接器14及一個八路選擇開關16。該SAS介面連接器12之數量可根據實際需要來設定，該八路選擇開關16可根據該SAS介面連接器12之數量選擇其他多路選擇開關。 Referring to FIG. 1, the SAS interface testing device 10 of the present invention is used to test the SAS interface on the motherboard. The preferred embodiment includes eight SAS interface connectors 12, a SAS hard disk interface connector 14 and an eight-way selection switch 16 . The number of the SAS interface connectors 12 can be set according to actual needs. The eight-way selector switch 16 can select other multi-way selection switches according to the number of the SAS interface connectors 12.
在該SAS介面測試裝置10之內部，該八個SAS介面連接器12上之電源引腳分別與該八路選擇開關16上之八個開關觸點1-8一一相連，該八路選擇開關16上之主端子0與該SAS硬碟介面連接器14上之對應電源引腳相連，該八個SAS介面連接器12上之其他引腳均與該SAS硬碟介面連接器14上之對應引腳相連(連接關係未示出)。本實施方式中，該八路選擇開關16為一自動控制開關，其可透過控制裝置以對其進行自動控制，如果考慮到成本之問題 ，該八路選擇開關16也可選用一手動控制開關。 Inside the SAS interface test device 10, the power pins on the eight SAS interface connectors 12 are respectively connected to the eight switch contacts 1-8 on the eight-way select switch 16, which are connected to the eight-way select switch 16 The main terminal 0 is connected to a corresponding power pin on the SAS hard disk interface connector 14, and the other pins on the eight SAS interface connectors 12 are connected to corresponding pins on the SAS hard disk interface connector 14. (The connection relationship is not shown). In this embodiment, the eight-way selector switch 16 is an automatic control switch that can be automatically controlled by the control device, if cost is considered. The eight-way selector switch 16 can also be selected with a manual control switch.
本實施方式中，以測試一具有八個SAS介面22之主機板20為例加以說明，測試前，使用SAS線纜將該待測主機板20上之八個SAS介面22分別與該八個SAS介面連接器12一一對應相連，將一SAS硬碟30與該SAS硬碟介面連接器14相連，將該主機板20與一主機板測試儀40相連，再將該主機板測試儀40之一控制端與該八路選擇開關16相連，用於控制該八路選擇開關16之運作，並在該主機板測試儀40之測試程式中加入控制該八路選擇開關16之相應程式。 In this embodiment, a test is performed by using a motherboard 20 having eight SAS interfaces 22 as an example. Before testing, the eight SAS interfaces 22 on the motherboard 20 to be tested are respectively connected to the eight SASs by using SAS cables. The interface connectors 12 are connected one by one, and a SAS hard disk 30 is connected to the SAS hard disk interface connector 14, the motherboard 20 is connected to a motherboard tester 40, and one of the motherboard testers 40 is connected. The control terminal is connected to the eight-way selector switch 16 for controlling the operation of the eight-way selector switch 16, and a corresponding program for controlling the eight-way selector switch 16 is added to the test program of the motherboard tester 40.
測試開始時，該八路選擇開關16上之主端子0與該八個開關觸點1-8中之一個觸點(例如觸點1)相連，則此時與該觸點相連之SAS介面連接器12(例如圖1中從上向下數第三個SAS介面連接器)之所有引腳將與該SAS硬碟介面連接器14之所有引腳對應相連，易知，該待測主機板20上對應之一個SAS介面22(例如圖1中從上向下數第三個SAS介面)與該SAS硬碟30實現了電性連接，此時測試程式控制該SAS介面22與該SAS硬碟30之間進行通訊並完成對該SAS介面22之測試。如果測試失敗，該主機板測試儀40將通知測試人員；如果測試成功，測試程式將控制該八路選擇開關16運作並使其上之主端子0與該八個開關觸點1-8中之另一個觸點(例如觸點2)相連，同理該待測主機板20上對應之一個SAS介面22(例如圖1中從上向下數第二個SAS介面)與該SAS硬碟30實現了電性連接，測試程式再控制該SAS介面22與該SAS硬碟30之間進行通訊 並完成對該SAS介面22之測試。之後，測試程式將按照上述過程依次測試其他SAS介面22，直到八個SAS介面22全部測試完畢為止，具體測試過程這裡不再贅述。 At the beginning of the test, the main terminal 0 of the eight-way selector switch 16 is connected to one of the eight switch contacts 1-8 (for example, the contact 1), and the SAS interface connector connected to the contact at this time is connected. All pins of 12 (for example, the third SAS interface connector from top to bottom in FIG. 1) will be connected to all the pins of the SAS hard disk interface connector 14, which is known to be on the motherboard 20 to be tested. Corresponding one SAS interface 22 (for example, the third SAS interface from top to bottom in FIG. 1) is electrically connected to the SAS hard disk 30, and the test program controls the SAS interface 22 and the SAS hard disk 30. Communication is performed and testing of the SAS interface 22 is completed. If the test fails, the motherboard tester 40 will notify the tester; if the test is successful, the test program will control the eight-way selector switch 16 to operate and make the other of the main terminal 0 and the eight switch contacts 1-8 A contact (such as contact 2) is connected, and a corresponding SAS interface 22 on the motherboard 20 to be tested (for example, the second SAS interface from top to bottom in FIG. 1) is implemented with the SAS hard disk 30. Electrically connected, the test program then controls communication between the SAS interface 22 and the SAS hard disk 30. The test of the SAS interface 22 is completed. After that, the test program will test the other SAS interfaces 22 in sequence according to the above process until all the eight SAS interfaces 22 have been tested. The specific test process will not be described here.
如果當該八路選擇開關16選用一手動開關時，該主機板測試儀40則不需與該八路選擇開關16相連以對其控制，測試時只要在每測試一個SAS介面22時將該八個開關觸點1-8中對應之一個觸點手動調整至與該主端子0相連即可。在測試每一SAS介面22時，由於其上之電源引腳是單獨與該SAS硬碟30之對應電源引腳相連的，相當於在測試其資料傳輸性能時也測試了其熱插拔之性能，故該測試方式同時達到了測試SAS介面資料傳輸性能及熱插拔性能之目的。本發明還可將該SAS介面測試裝置整合到該主機板測試儀40上，以進一步節省空間。 If the eight-way selector switch 16 selects a manual switch, the motherboard tester 40 does not need to be connected to the eight-way selector switch 16 for control thereof. The test only needs to be eight switches each time a SAS interface 22 is tested. The corresponding one of the contacts 1-8 is manually adjusted to be connected to the main terminal 0. When testing each SAS interface 22, since the power supply pin on it is separately connected to the corresponding power supply pin of the SAS hard disk 30, it is equivalent to testing its hot swap performance when testing its data transmission performance. Therefore, the test method achieves the purpose of testing the SAS interface data transmission performance and hot plug performance. The present invention can also integrate the SAS interface test device onto the motherboard tester 40 to further save space.
本發明SAS介面測試裝置由於採用了該八路選擇開關16對該八個SAS介面22進行選擇式測試，不需人力進行手動插拔SAS硬碟30之動作，而且也僅使用了一個SAS硬碟30，大大節省了測試時間，也降低了成本。 The SAS interface test device of the present invention performs the selective test on the eight SAS interfaces 22 by using the eight-way selector switch 16, and does not require manual operation for manually inserting and unplugging the SAS hard disk 30, and only uses one SAS hard disk 30. , which greatly saves test time and reduces costs.
