Zusammenfassung:Method and system for transferring data between a computing system and a storage device is provided. The system includes a storage controller including a frame snooper module that detects a TMR and generates a pause signal to a channel that stops the channel from sending any non-data frames to a buffer memory, wherein the channel continues to receive and process data frames while the channel is stopped from sending the command frames to the buffer memory; a counter for counting TMRs; and logic for generating an interrupt if a number of TMRs received exceeds a certain threshold value. The method includes detecting a TMR generating a command to stop a channel from receiving non-data frames while continuing to receive data frames from a Fibre Channel interface; and generating an interrupt to a processor after a certain number of TMRs are received.
