Abstract
An expander coupled between at least a first and second SCSI device for transmitting data and training patterns is provided. The expander includes, a first detection module for detecting a training pattern received from the first device; a second detection module that detects when a first section of the training pattern has been transmitted to the second device; and means for changing the expander's mode from a training mode to a repeat mode after the first section.
Claims9
A method for transmitting a training pattern to an expander coupled between at least a first and second SCSI device, comprising:
- detecting an end of transmission of a first section of the training pattern from the expander to the second device;
- and
- switching from a training mode to repeat mode for transmitting a second section of the training pattern after detecting the end of transmission of the first section of the training pattern.
An expander coupled between at least a first and a second SCSI device for transmitting data and training patterns, comprising:
- a first detection module for detecting a training pattern received from the first device;
- a second detection module that detects when a first section of the training pattern has been transmitted by the first device;
- and
- means for changing the expander's mode from a training mode to a repeat mode after the first section of the training pattern has been transmitted to the second device.
