Patent number: 8918559Abstract: Partitioning of a variable length scatter gather list including a processor for performing a method that includes requesting data from an I/O device comprising an I/O buffer. The requesting includes initiating a subchannel. The method further includes determining whether the subchannel supports data divisions by requesting SSQD data from the I/O device and inspecting at least one bit in the SSQD data. A determination is made whether the requested data includes a metadata block in response to determining that the subchannel support data divisions. Also, the subchannel is notified that the requested data includes the metadata block in response to determining that the requested data includes the metadata block. A location of storage is identified in an SBAL in response to notifying the subchannel.Type: GrantFiled: June 6, 2011Date of Patent: December 23, 2014Assignee: International Business Machines CorporationInventors: Stefan Amann, Gerhard Banzhaf, Ralph Friedrich, Raymond M.

Patent number: 8825892Abstract: A current value of a changing operating-system-level condition can be determined, wherein the operating-system level condition is a condition of a host related to an operating system resource utilization or an operating system experienced latency. The operating-system level condition can be a condition of a layer of the OSI model above the Data Link Layer. An inbound blocking factor algorithm can execute that uses the determined current value as a variable. A value for an inbound blocking factor can be generated as a result of executing the inbound blocking factor algorithm. The generated value can be utilized as the inbound blocking factor to determine a manner in which incoming messages are to be conveyed from a network adaptor, through an adaptor interface boundary, to an operating system of the host.Type: GrantFiled: April 14, 2008Date of Patent: September 2, 2014Assignee: International Business Machines CorporationInventors: Maurice Isrel, Jr., Thomas D.
