Problems solved by technology

[0003] However, depending on the design of the server, there must be a one-to-one connection between the host and the SAS ports on the SAS hard disk backplane in a specific order, otherwise it will cause the host to send commands to the wrong SAS hard disk , even data transmission cannot be performed normally

Abstract

A data transmission system for discriminating a connection error is applicable to a first device and a second device that are communicatively connected through a SAS interface. The first SAS port of the first device is used for communicating with the third SAS port of the second device, and the second SAS port of the first device is used for communicating with the fourth SAS port of the second device. A selected first pin in the first SAS port is coupled to the voltage supply node through the light emitting diode, and a selected second pin in the second SAS port is coupled to the voltage supply node through the light emitting diode. A selected third pin in that third SAS port is coupled to the ground terminal, and the selected third pin corresponds to the selected first pin and not to theselected second pin.

Description

technical field [0001] The invention relates to a data transmission system capable of identifying connection errors, in particular to a SAS (Serial Attached SCSI) interface data transmission system capable of identifying connection errors. Background technique [0002] Currently, in most servers, the host (Host) connects multiple SAS hard disks through the SAS (Serial Attached SCSI) interface, so as to greatly expand the storage function of the server. Generally speaking, since the host end and the SAS hard disk are respectively disposed on different devices or substrates, they still need to be connected through a SAS transmission cable. It should be understood that there are multiple SAS ports on the host or its SAS expansion adapter card, and similarly, the SAS hard disk backplane also has multiple SAS ports. [0003] However, depending on the design of the server, there must be a one-to-one connection between the host and the SAS ports on the SAS hard disk backplane in a...
