Abstract: A method for routing System Area Network (SAN) packets to multiple partitions within a single end node is provided. A range of Local Identification addresses (LIDs) are assigned to a channel adapter port within the SAN. Lower order bits within the LID are then assigned to select the particular partition in the end node. The Local ID Mask Control (LMC) field is used to assign multiple LIDs to a single port, using those low order bits to then route the message to the appropriate partition in the end node.

Abstract: A low-level function which enforces logical partitioning establishes a set of virtual indicator lights for certain physical components, the virtual indicator lights being only data in memory, a separate set of virtual indicator lights corresponding to each respective partition. Processes running in a partition can switch and sense the virtual indicator lights corresponding to the partition, but have no direct capability to either switch or to sense the virtual lights of any other partition. The low-level enforcement function alone can switch the state of the physical indicator light, which is generally the logical OR of the virtual indicator lights of the different partitions.

The differential driver circuit includes a variable resistance circuit on each leg of the differential driver circuit. A replica of one leg of the differential driver circuit is configured for adjusting the variable resistance circuits so that the differential driver circuit's source resistance appears to a load as substantially similar to the termination resistance.

Abstract: The present invention relates to systems and methods to port controller state and context via non-volatile portable memory to controllers employing an open operating system. The present invention provides for saving a controller's state and context, for example after the controller has been suitably configured. The saved image can then be employed for subsequent controller startups to resume a particular state and context, utilized during maintenance to return a controller to a previously saved state and context, and employed to efficiently configure similar controllers via porting and/or loading the saved image to the similar controllers, which mitigates manual controller configuration. The present invention can be employed in connection with various industrial controller designs, memory configurations, and data transfer techniques. In addition, the present invention provides for serial and/or concurrent state and context transfers between controllers and memory devices.

Abstract: A method for associating reliable datagram queue pairs with an underlying end-to-end context of a channel adapter is provided. The method comprises storing a reliable datagram domain (RDD) within the context of a reliable datagram queue pair (RD QP). The same RDD is stored within an end-to-end context (EEC). A partitioning key (P—key) is also stored within the EEC. The RDD cannot be accessed by consumer processes. In the case of incoming messages, the P—keys of the incoming data packet and EEC are compared. If P—keys match, then the RDD's of the RD QP and EEC are compared. If the RDD's match, the packet is processed normally. In the case of outgoing messages, the RDD's of the RD QP and EEC are first compared, and if they match, the P—Key of the EEC is inserted into the transport header of the data packet.

Abstract: A method in a network computing system for managing a plurality of subnet managers in the network computing system. An identification is received of a set of subnet managers within the plurality of subnet managers. The set of subnet managers is allowed to participate in a master election to select a master subnet manager. Subnet managers other than the set of subnet managers are placed in a dormant state. The master subnet manager is elected from the set of subnet managers through the master election, wherein other subnet managers within the number of subnet managers poll the master subnet manager to allow the other subnet managers to elect a new master subnet manager if the master subnet manager fails.

Abstract: A method, system, and apparatus for preventing input/output (I/O) adapters used by an operating system (OS) image, in a logically partitioned data processing system, from fetching or corrupting data from a memory location allocated to another OS image within the data processing system is provided. A hypervisor prevents transmission of data between an input/output adapter in one of the logical partitions and memory locations assigned to other logical partitions during a direct memory access (DMA) operation by assigning each of the input/output adapters a range of I/O bus DMA addresses. The I/O adapters (IOAs) are connected to PCI host bridges via terminal bridges. A single terminal bridge may support multiple IOAs, in which case every terminal bridge has a plurality of sets of range registers, each associated with a respective one of the IOAs to which it is connected. An arbiter is provided which selects one of the input/output adapters to use the PCI bus.

Abstract: A method for determining the security level associated with transmissions in a telecommunications network includes means for alerting parties of the security status of the transmission.

Alternatively, the parties may elect to decline or alter content of the communications to preserve integrity.

Abstract: A method in a node within network computing system for selecting a master network manager, wherein the first node is associated with a first priority. Requests are sent to the network computing system to discover other nodes within the network computing system. A second priority from the request is identified in response to receiving a response to one of the requests from another node within the network computing system. The first node shifts to a standby mode if it discovers a master subnet manager or the second priority is higher than the first priority. The first node shifts to a master mode if a response containing a priority higher than the first priority is absent in responses received by the first node and the first node has completed checking all other nodes in the network computing system.

Abstract: A computer system has physical pages of memory subject to access by input/output (“I/O”) devices, and a certain table with entries associating the physical pages with the I/O devices. Responsive to a request for data be moved from a first physical page to a second physical page, an entry is selected for the first physical page in the table. The selected entry indicates an association of the first physical page and one of the I/O devices. Arbitration is temporarily disabled for the selected I/O device so that I/O operations for the I/O device are temporarily disabled. Once arbitration is disabled for the device the data is moved from the first physical page to a second one of the physical pages and the entry is updated in the table to reflect a new association between the I/O device and the second physical page.

Abstract: The present invention relates to a system and methodology for saving and restoring controller state and context in an industrial controller.

Abstract: A method for enabling a Q_key that is tamper proof from applications on a distributed computer system to protect selected network operations is provided. Applications and an operating system (OS) execute on the end nodes and each may access various network resources. In the invention, the network resources are configured for selective access by particular applications or OS. In a preferred embodiment, a control bit of a Q_key, which allows applications to authenticate their use of particular communication resources, i.e., the send and receive queues, is reserved and utilized to signal whether a particular application is allowed access to the resources. Setting the control bit to 0 allows the Q_key to be set by an application directly. When the control bit is set to 1, the Q_key cannot be set by an application and can only be set using a privileged operation performed only by the OS.
