A method for smart mounting of a first storage device to a first server includes receiving, at a first peer-to-peer communication component of a first server, a request from a second peer-to-peer communication component of a second server, the request being a request to mount a first storage device to said first server. The request is a request to mount a first storage device to said first server. The request is using a peer-to-peer communication protocol between the first and the second peer-to-peer communication components without using a central instance between the first and the second server.

Smart mounting of storage devices

A method for smart mounting of a storage device to a server may be provided. The method comprises providing a first peer-to-peer communication component to a first server a first storage device is controlled by, and providing a second peer-to-peer communication component to a second server a second storage device is controlled by. The method also comprises requesting, by said second server, a mounting of said first storage device of said first server using a direct communication between said first peer-to-peer communication component, and said second peer-to-peer communication component using a peer-to-peer communication protocol between said first and said second peer-to-peer communication component without using a central instance between said first and said second server, and providing mounting information of said first storage device to said second peer-to-peer communication component without using said central instance.

A method is presented for reliably operating at least one sensor connected to a central control unit. Each sensor senses a sensor value for its sensor parameter and creates an interrupt to the control unit when its sensor value is outside a sensor value range limited by an upper and a lower threshold. Upon generation of an interrupt by a sensor, a modified sensor value range is calculated so that the sensor value causing the interrupt lies within the modified sensor value range, and the modified sensor value range is applied to the respective sensor. The method further includes repeatedly verifying correct behavior of each sensor. A computer-readable medium, a computer program product, and a system for executing the above-summarized method are also presented.

Method for reliably operating a sensor

Retrieval of status information from a remote device performed on a host system is provided, wherein the remote device is connected to the host system via a bus system comprising at least two signal lines terminated with resistors on the host system side and on the remote device side. The retrieval method includes: activating a sensing phase; sensing the at least two terminated signal lines during the sensing phase; and determining operating state of the remote device based on the sensing result; wherein at least a first operating state representing a connected and powered remote device is detectable.

Retrieving status information from a remote device and corresponding host system

A data processing system boots at least one service processor controlling at least one PCIe card in an I/O unit. The data processing system boots a second service processor located in a processor unit, wherein the processor unit and I/O unit are interconnected using functional path conductors, wherein functional path conductors are according to PCIe standard. The data processing system reads location information from the first at least one service processor, wherein the location information is reported for each PCIe card prior to initializing a functional path to the PCIe card. The data processing system sends location information from the second at least one service processor to a system controller. The data processing system initializes the PCIe card and a hub card of the processor unit in order to initialize a functional path and configures the I/O unit by communicating configuration commands over the functional path.
