摘要： A computer implemented method monitors activity within a device driver layer of a computer. An arrival rate is identified within a device driver for the node. The arrival rate is a rate at which packets arrive at a network adapter of the node from all other nodes within a network. If the arrival rate exceeds at least one threshold, the node undergoes a state change. The at least one threshold delineates between a plurality of states for the node.

摘要： One embodiment for dynamically loading a service onto a node includes requesting, by a service requester, of a service from a service broker. Further, the method includes selecting, by the service broker, of the node among the nodes. Further still, the method includes re-booting, by the service broker, of the node based on the selecting, and then requesting, by the node, of an image from a TFTP relay agent for the service for the node. Yet further, the method includes querying, by the TFTP relay agent, for a type of the service from the service broker for the node, and then downloading of the image for the type of the service from a software repository accessed by the TFTP relay agent to the node. Finally, the method includes booting, by the node, to the image, informing the service requester that the service is ready for use, and using the service.

摘要： A computer implemented method, a tangible computer medium, and a data processing system are provided for waking a blade server from an operational state of reduced power. When server blade enters the state of reduced power, a service firmware configures a multi-port blade switch of the server blade to direct incoming packets to the service firmware. The service firmware then polls for receipt of a Wake-on-Lan magic packet. When the Wake-on-Lan magic packet is received by the service firmware, the service firmware reconfigures the multi-port blade switch to direct incoming packets to a network interface card of the server blade. The service firmware then initiates a reboot of the server blade.

摘要： A computer implemented method, a tangible computer readable medium, and a data processing system intelligently propagate link status information received by a blade server to the various ports of an embedded multi-port switch. The link status of a switch port in an external switch module can be communicated to the operating systems of individual blade servers that are affected by that link status. When an external switch module is unplugged from a server blade chassis, the bus controller broadcasts a link down event, such as a link down interrupt, to the individual server blades where it is received by the embedded multi-port switch for those server blades. The embedded multi-port switch translates the link down interrupt into a hardware link down event, and forwards the hardware link down event to the other elements connected to the embedded multi-port switch.

摘要： A kernel extension is configured to intercept a call to associate a socket with a port of a node in a network. The call originates from a kernel of the node. The kernel extension is configured to determine the port from the call. The kernel extension is configured to determine that the port is one of a plurality of ports for which the node has authority to modify firewall rules of a firewall of the network. The kernel extension is configured to modify firewall rules maintained by the firewall to allow communications for the port to the node through the firewall.

摘要： A method, system, and computer program product for a self-adjusting application heartbeat management process are provided in the illustrative embodiments. A first application receives from a second application, a response message in response to a heartbeat message. Information is identified in the response message usable for computing a delay in a future response message for a future heartbeat message, such that the information communicates to the first application a system condition existing in the second data processing system where the second application is executing. A response time is adjusted using the information to form a modified response time. The future response message is received after the response time.

摘要： In a method for regulating network bandwidth in a virtualized computer environment, a computer having a hypervisor program receives a request from a first virtual client to transmit data. In response, the computer transfers the data from a memory of the first virtual client to a memory of a virtual server. The computer receives an error notification from a shared virtual network adapter of the virtual server, indicative of insufficient network bandwidth available to transmit the data. In response, the computer notifies the first virtual client that insufficient network bandwidth is available to transmit the data.
