Abstract: Various embodiments are generally directed an apparatus and method for receiving an event notification for a pair of cluster nodes having a first cluster node and a second cluster node, the event notification indicating an occurrence of a takeover event or a giveback event. Further, various embodiments may include suspending copying of information from a source logical unit to a target logical unit, transferring one or more processes from the first cluster node to the second cluster node and resuming importation of information from the source logical unit to the target logical unit.

Abstract: In a method for providing a cloud-based computing service to a user, a request for the computing service to be performed for the user is received, in which, the request includes a selection of at least one flow-slice, the at least one flow-slice comprising a network abstraction of a network pay-per-use unit. In addition, workloads to be performed by a plurality of infrastructure components to satisfy the at least one flow-slice are estimated and a provisioning scheme for the plurality of infrastructure components to implement the estimated workloads on the plurality of infrastructure components is determined.

Abstract: A method of managing power supply to at least one device in a data processing system, the method comprising determining when the at least one device has been associated with no resources for a predetermined period of time; turning off the power supply to the at least one device; determining that the at least one device is required for use by the data processing system; and restoring the power supply to the at least one device.

Abstract: A method of recovering from an operating system crash or failure in a first memory. Upon detecting the crash or failure, a second memory provided as auxiliary memory to the first memory and being of equal size to the first memory is initialized, the operating system is booted in the second memory, content of the first memory is dumped to a dump storage device, and the first memory is prepared for use as auxiliary memory.
