A method for dynamically allocating buffer credits between a system and a storage area network (SAN). The method includes one or more computer processors determining a forecast of a change related to a pattern of network traffic that originates from a computing system that links to a storage area network (SAN) via a network connection. The method further includes determining whether the forecast change related to the pattern of network traffic dictates a change to a buffer credit allocation associated with the network connection. The method further includes responding to determining that the forecast change related to the pattern of network traffic dictates the buffer credit allocation change by determining a value for the buffer credit allocation associated with the change. The method further includes transmitting a request to a switch of the SAN to modify a buffer credit allocation value corresponding to a port of the switch linked to the network connection.
