Appl. No.:

13/097510

Inventors:

Gabriel Alatorre - Long Beach CA, US
Aameek Singh - University Place WA, US
Laura Richardson - Ridge Manor FL, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/50
G06F 9/45
G06F 3/00
G06F 13/28
G06F 13/00

US Classification:

710 33, 703 13, 703 22, 710 5, 710 15, 710 29

Abstract:

Managing a data transfer from one or more source storage devices to one or more target storage devices. The data transfer comprises concurrent transfer of a multiplicity of data units pursuant to respective data transfer commands. The concurrent transfer of the multiplicity of data units is currently in-progress. A computer determines a currently-overloaded storage component involved in the data transfer. The computer determines a plurality of the data transfer commands that involve the overloaded storage component. The computer determines an approximately-minimum number of the data transfer commands to cancel to stop overload of the overloaded storage component. In response, the computer cancels the minimum number of the data transfer commands.

US Classification:

Abstract:

Scheduling a proposed additional data transfer from one or more source storage devices to one or more target storage devices. A computer receives a request for the proposed additional data transfer, and in response, determines a measure of the proposed additional data transfer. The computer determines a measure of recent actual data transfers. The recent actual data transfers involve one or more of the source storage devices and one or more of the target storage devices. In response to the request for the proposed additional data transfer, the computer estimates performance of one or more of the source storage devices and one or more of the target storage devices that would occur during the proposed additional data transfer based on the measure of recent actual data transfers combined with the measure of the proposed additional data transfer. The computer compares the estimated performance to a corresponding performance threshold, and if less, the computer postpones execution of the proposed additional data transfer.
