Abstract: A method, computer program product, and computer system to maintain high availability of a service processor. An embodiment provides program code with a location of a second service processor (the second service processor is communicatively coupled to the first service processor). The program code stops a virtual machine during runtime, including instruction execution and IO operations, where during runtime, the virtual machine executes one or more processes to service and manage computing resources in the distributed computing environment. The program code generates a micro-checkpoint of the virtual machine. The program code resumes the instruction execution of the virtual machine and transmits the micro-checkpoint to a second service processor based on the location and then resumes IO operations. The second service processor utilizes the micro-checkpoint to enable a hypervisor on the second service processor to start a virtual machine on the second service processor.

At least one interlock enables the large or small suction cup to be deployed. The interlocks include passive interlocks, such as ball detents and conventional magnets, and active interlocks, such as a twist lock and electronic actuated magnets.

Abstract: Embodiments of the present invention include a memory module that includes a plurality of memory devices and a memory buffer device. Each of the memory devices are characterized as one of a high random bit error rate (RBER) and a low RBER memory device. The memory buffer device includes a read data interface to receive data read from a memory address on one of the memory devices. The memory buffer device also includes common error correction logic to detect and correct error conditions in data read from both high RBER and low RBER memory devices. The common error correction logic includes a plurality of error correction units which provide different complexity levels of error correction and have different latencies. The error correction units include a first fast path error correction unit for isolating and correcting random symbol errors.

Abstract: An aspect includes detecting a recurring intermittent error in a path of a network in a system that includes at least one data transmission port configured for connection to at least one shared data storage device via a plurality of paths of the network. It is determined by a path control module (PCM) in the network, whether a path recovery action has been initiated by a fiber channel protocol driver in the network. In response to determining that the path recovery action has not been initiated, the data transmission port is prevented from accessing the path for a specified time period by moving the path into a degraded sub-state, and subsequent to the specified time period the data transmission port is provided access to the path. In response to determining that the path recovery action has been initiated, the data transmission port is provided access to the path.

Abstract: A secure cloud computing environment protects the confidentiality of application code from a customer while simultaneously protecting the confidentiality of a customer's data from intentional or inadvertent leaks by the application code. This result is accomplished without the need to trust the application code and without requiring human surveillance or intervention. A client secure virtual machine (SVM) is accessible by a client who supplies commands, operand data and application data. An appliance SVM has the application code loaded therein and includes an application program interface that accesses a memory area shared by both SVMs. All access to the appliance SVM is initially revoked by an ultravisor, except for the shared memory. The appliance SVM processes the commands without ever saving any persistent state of the application data. The ultravisor manages an SVM by maintaining exclusive control over a device tree used by the operating system of the SVM.

Abstract: A system for explosively applying a fire-fighting foam is provided. The system includes a thermoelectric generator that is attached to a battery heat source. A temperature differential across the thermoelectric generator generates an electrical current having a temperature-dependent voltage. A detonator circuit is electrically connected to the thermoelectric generator. The detonator circuit measures the voltage of the electrical current. An explosive foam applicator is communicatively connected to the detonator circuit and includes a trigger mechanism that detonates a propelling charge in response to receiving a signal from the detonator circuit when the detonator circuit determines that the electrical current corresponds to temperature that is greater than or equal to a threshold temperature. The explosive foam applicator is oriented such that detonating the propelling the charge causes the explosive foam applicator to apply a foam to the battery heat source.
