Patent number: 7975027Abstract: Provided are a method, system, and article of manufacture for credit depletion notification for transmitting frames between a port pair. Credits indicate a number of outstanding frames a first device may transmit to a second device. The credits are decremented in response to transmitting a frame to the second device. The credits are incremented in response to receiving a ready code from the second device indicating that the second device processed the transmitted frame. A determination is made as to whether additional credits are needed for communicating frames from the first device to the second device. A credit depletion notification is sent to the second device in response to determining that the additional credits are needed for communication with the second device.Type: GrantFiled: August 6, 2007Date of Patent: July 5, 2011Assignee: International Business Machines CorporationInventors: Louie Arthur Dickens, Roger Gregory Hathorn, Nils Haustein, Craig Anthony Klein, Daniel James Winarski

Publication number: 20110145633Abstract: Described are embodiments of an invention for blocking write access to memory modules of a solid state drive. The solid state drive includes a controller access module or a memory access module that controls write access to the solid state drive and the memory modules of the solid state drive. Upon determining that a memory module has failed, the failed memory module or the entire solid state memory device is configured to be read only to prevent an errant write of data over critical data. Further, a failed memory module, or solid state device memory having a failed memory module, may be replaced upon failure.Type: ApplicationFiled: December 15, 2009Publication date: June 16, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Louie Arthur Dickens, Timothy A.

Patent number: 7809865Abstract: A method to set a communication speed in a Serial-Attached Small Computer System Interface (“SAS”)/Serial-ATA (“SATA”) distance extender apparatus comprising a plurality of supported communication speeds and a local communication speed, a fibre channel interface, a memory, a processor, and a communication bus interconnecting the SAS/SATA Interface, the Fibre Channel interface, the memory, and the processor. The method detects traffic received by the Fibre Channel interface, and determines if the traffic comprises a SAS/SATA Open Address frame. If the traffic comprises a SAS/SATA Open Address frame, the method then determines if the local communication speed matches a communication speed utilized by an interconnected remote SAS/SATA Interface. If the local communication speed matches a communication speed utilized by an interconnected remote SAS/SATA Interface, the method transmits the traffic using the local SAS/SATA Interface.Type: GrantFiled: April 25, 2008Date of Patent: October 5, 2010Assignee: International Business Machines CorporationInventors: Louie Arthur Dickens, Craig Anthony Klein, Timothy A.
