Publication number: 20140090082Abstract: A data connection of a shared resource is placed in isolation mode to remove its ability to communicate with other data connections of the shared resource. This ability to isolate the data connection is dynamic in that it can be turned on/off at any time. This provides increased data security for the entities using the data connection.Type: ApplicationFiled: November 12, 2013Publication date: March 27, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Angelo MACCHIANO, Bruce H.

Publication number: 20130305247Abstract: Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.Type: ApplicationFiled: July 22, 2013Publication date: November 14, 2013Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Janet R.

Patent number: 8478922Abstract: The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.Type: GrantFiled: June 23, 2010Date of Patent: July 2, 2013Assignee: International Business Machines CorporationInventors: Brenton F. Belmar, David Craddock, Janet R. Easton, Mark S. Farrell, Thomas A. Gregg, Damian L. Osisek, Donald W. Schmidt, Gustav E. Sittmann, III, Richard P. Tarcza

Patent number: 7992149Abstract: A method for communicating from a first virtual machine, defined by a virtual machine operating system, to an external device via a local area network (LAN). The virtual machine operating system also defines other virtual machines and a base portion common to all of the virtual machines. The first virtual machine writes an IP datagram to an output buffer allocated to the first virtual machine. The IP datagram comprises data and a destination IP address associated with the external device. The program functions in the base portion read the IP datagram from the output buffer to determine the destination IP address and then copy the IP datagram from the output buffer into storage allocated to the common base portion whereby the IP datagram passes from the first virtual machine into the common base portion storage without passing through any other virtual machines. Then, the program functions request a tangible adapter card for the network to send the IP datagram to the IP destination address.Type: GrantFiled: February 20, 2008Date of Patent: August 2, 2011Assignee: International Business Machines CorporationInventors: Mary Ellen Carollo, Susan Marie Farrell, Angelo Macchiano, Dennis R.
