Aspects of the present invention disclose a DIMM extraction tool for extracting a DIMM from a DIMM socket. Exemplary embodiments of the DIMM extraction tool include a frame adapted for use as an air baffle within the DIMM socket, a first arm and a second arm pivotably connected to the frame. When the first arm and second arm are in a resting position, the first and second arm respectively engage a first resting detent and a second resting detent to prevent pivotable rotation of the first arm and second arm in exemplary embodiments of the DIMM extraction tool. When the first arm and second arm are in a working position, the first arm and second arm respectively are adapted to releasably engage the DIMM and bias resilient latching arm of the DIMM socket.

A method includes performing operations on a compute node including a plurality of processors each having a local PCI processing element and a local processor interconnect, wherein the local processor interconnect of each processor is connected to the local processor interconnect of at least one other processor. The method further includes identifying a PCI device that is directly attached to the local PCI processing element of a first one of the processors and positioned in an upstream airflow direction from the first processor. The operating system monitors the PCI device and, in response to determining that the PCI device is performing a power-intensive operation, directs operations away from the first processor to a second one of the processors, wherein the local processor interconnect of the second processor is directly connected to the processor interconnect of the first processor.

Minimizing thermal impacts of local-access PCI devices

A method for securing a serial bus shared by a control module and one or more subordinate electronic devices, the serial bus having a protocol specifying that messages on the serial bus have a source address and a destination address. The method comprises examining, by one or more processors of the control module, each message appearing on the serial bus that was not originated by the control module; identifying, by one or more processors of the control module, a suspect message that satisfies one or more suspect message criteria. The method includes updating, by one or more processors of the control module, an event metric, and testing to determine whether a threshold has been exceeded; and in the event the threshold has not been exceeded, initiating, by one or more processors of the control module, a co-transmission sufficient to disrupt consumption of the suspect message by a subordinate device.

Securing a shared serial bus

An electronic system comprises: a pin sensor; and an integrated management module, wherein the integrated management module: identifies a location of a damaged connector between a semiconductor chip and a hardware socket, wherein the location of the damaged connector is described by one or more readings from the pin sensor, and wherein the damaged connector prevents a particular signal from being supplied to the semiconductor chip via the hardware socket; identifies the particular signal as an input for a particular semiconductor function; determines whether the semiconductor chip provides the particular semiconductor function; and adjusts a use of the semiconductor chip based on whether or not the semiconductor chip uses the particular signal to provide the particular semiconductor function.

Adjusting the use of a chip/socket having a damaged pin

Administering a remote session between a target computing device and a remote computing device, including: identifying, by a remote session administration module, a confidentiality level of content displayed by a target computing device, the target computing device engaged in a remote session with remote computing device, the remote session carried out by software executed by the target computing device, software executed by the remote computing device, and an active data communication link between the target computing device and the remote computing device; and controlling, by the remote session administration module, the remote session in dependence upon the confidentiality level of content displayed by the target computing device.

Embodiments of the invention provide a method, system and computer program product for dynamically locating a device within a data center. A method for dynamically locating a device within a data center includes wirelessly receiving in a fixed device amongst a multiplicity of devices in a data center, a request from a mobile device to locate a target device amongst the devices. The method also includes broadcasting a request to the multiplicity of devices to establish respective wireless identifiers based upon a proximity of each of the multiplicity of the devices to the target device relative to adjacent ones of the devices. The method yet further includes establishing a wireless identifier for the fixed device based upon a wireless identifier of an adjacent one of the devices. Finally, the method includes returning to the mobile device by the fixed device the established wireless identifier for the fixed device.

An I2C system comprises an inter-integrated circuit (I2C) master device coupled to an I2C multiplexer via a master I2C bus. A plurality of slave I2C busses emanating from the I2C multiplexer couple the I2C multiplexer to a plurality of I2C slave devices. Each of the slave I2C busses comprises a serial data (SDA) line and serial clock (SCL) line. Each of the slave I2C busses, which is coupled to two I2C slave devices, has a first channel and a second channel. The first channel puts bidirectional serial data on the SDA line and clock signals on the SCL line, and the second channel puts bidirectional serial data on the SCL line and clock signals on the SDA line. A channel selector, associated with the I2C multiplexer, selectively couples the I2C master device to one of the two I2C slave devices via the first channel or the second channel.

Double density I2C system

An apparatus, system, and method are disclosed to failover to a standby server when a primary server is under broadcast storm or denial-of-service ('DoS') attack. A primary attack sensing module is included to monitor a rate of incoming data from a computer network to a primary server and to determine if the rate of incoming data is above a primary data rate threshold. A standby contact module is included to request a standby data rate status from a standby server in response to the primary attack module determining that the rate of incoming data to the primary server is above the primary data rate threshold. The standby server is connected to the primary server over a private network. The standby data rate status includes a determination by the standby server of whether a rate of data received by the standby server is above a standby data rate threshold. A standby receiver module is included to receive a standby data rate status from the standby server over the private network. A switchover module is included to deactivate the primary server and to send a command to activate the standby server as a primary server in response to the received standby data rate status indicating that the rate of data received by the standby server has not exceeded the standby data rate threshold.

A computing system is provided with real-time capabilities so that the system is capable of running applications such that one or more real-time criteria are satisfied. An interrupt architecture of the computing system is disabled. The interrupt architecture generates interrupts sent to a firmware of the computing system in response to events. A different architecture is substituted within the computing system for the interrupt architecture. The different architecture is responsive to the events without violating the real-time criteria. In response to the events occurring, the different architecture causes one or more corrective actions to be performed.
