Techniques are disclosed for automated detection and notification of interconnect errors or failure. An interconnect is tested via passive or active means. Error data associated with data transferred via the interconnect is measured and analyzed to generate error statistics. Error statistics are then used to determine an error rate of the interconnect and an alert is generated if the error rate exceeds a threshold. Alerts are displayed to users for troubleshooting and/or for indication that the interconnect should be replaced.

Monitoring interconnect failures over time

A mechanism for exchanging information between SCSI devices which allows for specifying multiple source or destination buffers. The mechanism includes a first apparatus for generating at least one move instruction which when executed by the SCSI manager either writes or reads the specified number of bytes to or from that buffer address and subsequently adds the offset field value to the buffer address to create a current buffer address. The current buffer address and the buffer address may be non-contiguous. The mechanism also has a second apparatus for generating at least one looping instruction by which the SCSI manager branches the offset number of instructions until the number is exhausted. This allows the SCSI manager to repeat instructions. During each repetition of the move instruction, the buffer address location gets incremented by the value in the offset field. This incrementing allows buffer locations to be accessed that are non-contiguous; thus, multiple source and destinations can be created and they can be non-contiguous.
