IBM Assigned Three Patents

System, method and program product to manage
transfer of data to resolve overload of storage system

IBM Corp., Armonk, NY, has been assigned a patent (8,341,312) developed by Gabriel Alatorre, Long Beach, CA, Aameek Singh, University Place, WA, and Laura Richardson, Ridge Manor, FL, for a "system, method and program product to manage transfer of data to resolve overload of a storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "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."

The patent application was filed on April 29, 2011 (13/097,510).

Apparatus and method to set signal compensation settings
for storage device

IBM Corp., Armonk, NY, has been assigned a patent (8,341,373) developed by Brian J. Cagno, Robert A. Kubo, and Gregg S. Lucas, Tucson, AZ, for an "apparatus and method to set signal compensation settings for a data storage device."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method is disclosed to set signal compensation settings for a data storage device comprising a first port and a second port, where that first port is interconnected to a first switch via a first communication pathway having a predetermined first length. The method determines first signal compensation settings based upon the first length."

The patent application was filed on Aug. 21, 2008 (12/196,169).

Managing power consumption and performance
in storage system

IBM Corp., Armonk, NY, has been assigned a patent (8,341,437) developed by Miriam Allalouf, Ronen Kat, and Kalman Z. Meth, Haifa, Israel, for "managing power consumption and performance in a data storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method for managing power consumption in a data storage system is provided. The method comprises receiving a first input/output (I/O) request identifying an I/O operation to be performed by a storage device; delaying scheduling of the first I/O request to manage amount of power consumed by servicing the first I/O request; and forwarding the first I/O request to a storage controller associated with the storage device. The storage controller schedules the first I/O request using a scheduling mechanism, and the storage device services the first I/O request according to the scheduling mechanism."

The patent application was filed on June 30, 2009 (12/494,288).
