Embodiment Construction

[0023] Below with reference to shown in accompanying drawing, the present invention is further described by specific embodiment:

[0024] A kind of loopback test method of SAS storage board, SAS storage board includes one or more SAS channels, such as figure 1 As shown, the SAS channel includes a signal sending end and a signal receiving end. The signal sending end is responsible for transmitting data to the target channel, and the signal receiving end is responsible for receiving data from the target channel, such as figure 2 As shown, the test method connects the signal sending end of the SAS channel of the SAS memory card with the signal receiving end, and judges the quality of the channel by comparing the difference between the received signal and the sent signal.

[0025] The signal sending end of the SAS channel is connected to the signal receiving end as follows: the Tx+ signal line of the SAS channel is connected to its own Rx+ signal line, and the Tx- signal line is ...

Abstract

The invention discloses a loopback test method and device for an SAS storage board card. The test method includes that connecting the signal transmitting end of an SAS channel of the SAS storage board card with the signal receiving end, and judging the quality of the channel through comparing the difference between the received signal and transmitted signal. The loopback test device for the SAS storage board card comprises the signal receiving end and transmitting end of the SAS channel, wherein the signal receiving end of the SAS channel is connected with the signal transmitting end to form a loopback SAS channel. The loopback test method and device are capable of greatly reducing the production and detection cost for the storage board card, shortening the detection time and improving the detection quality.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a loopback testing method and device for a SAS storage board. Background technique [0002] In the production inspection of SAS storage boards, there is a link to the inspection of the SAS channel, that is, to check the stability of the SAS channel. [0003] The current detection is generally to judge the quality of the SAS channel by connecting the hard disk for reading and writing tests. The disadvantages of this test method are: more hard drives need to be prepared, the test time is long, the hard drive itself is also an unstable factor, and the test results cannot accurately measure the quality of the SAS channel. With more and more SAS channels of SAS boards, the detection process of SAS channels needs to consume a lot of time and cost. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a testing method and devic...
