A method according to one embodiment may include receiving data in a receive buffer, the receive buffer comprising a plurality of buffers, and sending a hold command to a transmitting node currently sending data to hold transmission of additional data when a level of the data in the receive buffer reaches a high threshold level. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

Receive buffer in a data storage system

One embodiment of a method may include, in response, at least in part, to one or more received frames, generating an interrupt and preventing transmission of one or more other frames. The one or more received frames may indicate, at least in part, an error condition or a commencement of a data transfer. The method of this embodiment also may include, in response, at least in part, to the interrupt, executing one or more instructions. The one or more instructions, when executed, may optionally result in deleting the one or more other frames, and if the one or more received frames indicate, at least in part, the error condition, commencing recovery from the error condition. If the one or more received frames indicate, at least in part, the commencement of the data transfer, the method of the embodiment may include storing data associated with the data transfer.

Race condition prevention

A method according to one embodiment may include receiving a frame, determining a frame type of the frame, accessing a location of memory associated with the frame type, the location comprising at least one programmable data element, and checking a validity of the frame in response to data in the location of memory associated with the frame type. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
