Abstract:
1. A method for managing a data transfer from one or more source storage devices to one or more target storage devices, the data transfer comprising transfer of a multiplicity of data units pursuant to respective data transfer commands, the method comprising the steps of: determining, by one or more processors, a currently-overloaded storage component involved in the data transfer; determining, by one or more processors, a plurality of the data transfer commands that involve the storage component; and determining, by one or more processors, a target number but not all of the data transfer commands that involve the storage component to cancel to avoid the overload of the storage component, the one or more processors determining the target number by modeling an effect on the load of the storage component of hypothetically cancelling one or more different numbers of the data transfer commands that involve the storage component; and canceling the target number of the data transfer commands that involve the storage component.
