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 capable of judging connection errors is applicable to a first device and a second device that can be communicated through a SAS interface. The first SAS port of the first device is used for communication connection with the third SAS port of the second device, and the second SAS port of the first device is used for communication connection with the fourth SAS port of the second device. Selected first pins in the first SAS port are coupled to the voltage supply node through LEDs, and selected second pins in the second SAS port are coupled to the voltage supply node through LEDs. The selected third pin in the third SAS port is coupled to the ground terminal, and the selected third pin corresponds to the selected first pin, but does not correspond to the selected second pin.

Description

Technical field [0001] The present invention is about a data transmission system that can be identified connection error, in particular a SAS (Serial Attached SCSI) interface data transmission system that can determine the connection error. Background [0002] Currently, in most servers, the Host connects multiple SAS drives through the Serial Attached SCSI interface to greatly expand the storage capabilities of the server. In general, since the host side and the SAS hard drive are set up on different devices or substrates, they still need to be connected via the SAS transmission cable. It should be noted that there are multiple SAS ports on the host side or its SAS Expansion Adapter Card, and similarly, the SAS hard drive backplane has multiple SAS ports. [0003] However, depending on the design of the server, the one-to-one connection between the host side and the SAS port of the SAS hard disk backplane must be in the specific order in which it is designed, otherwise it will c...
