Zusammenfassung:A computer-implemented method is disclosed to enhance command burst tolerance in a SCSI system. The method starts with receiving an initiator timeout value at a SCSI target, where the SCSI target is communicatively coupled with a SCSI initiator through a set of communication links, and where the initiator timeout value is associated with a timeout duration after which the SCSI initiator times out if receiving no response from the SCSI target after sending a SCSI command. After receiving the initiator timeout value, the SCSI target determines how long a SCSI command has been pending to be processed at the SCSI target. The SCSI target then returns a response for the SCSI command to the SCSI initiator within the timeout duration associated with the initiator timeout value even if the SCSI command is pending to be processed at the SCSI target.
