Abstract

A switch including a processor and method for monitoring bandwidth in the storage switch (204). The switch includes at least one physical port coupling at least one target (206) and at least one initiator (102) via the physical port (250). The monitoring method may include the steps of determining whether congestion occurs on the physical port and assigning a weight to bandwidth usage between the initiator and the target based on a minimum (220,224) and maximum bandwidth (222,226) settings for each target. The switch may further include a step of controlling bandwidth usage by ea of said at least two targets based on minimum and maximum bandwidth settings for each of the targets.
