Methods for dynamic enabling and di save ring of XFR_RDY, computer programs, and system (dynamic enabling and di save ring of XFR_RDY)

摘要

Problem to be solved: to provide a method for dynamically endowing and saving the use of xfrrdy.In one embodiment of the present invention, such a method determines whether or not XFR RDY is enabled or disabled for a write command to receive a write command at the target . If xfrrdy is disabled, this method determines whether one or more buffers are available at the target. If at least one buffer is available, this method processes the write command by writing data associated with the write command into one or more buffers. The method then returns information indicating the number of buffers still available for the target after the write command is completed. In this specification, corresponding devices and computer program products are also disclosed and claimed.Diagram
