In some examples, a management controller includes a communication interface to communicate with a computing device, where the management controller is separate from a processor of the computing device. The management controller includes a management processor to receive, from the computing device, a first hash value that is based on a first hash function applied on an input value and a salt, generate a second hash value based on applying a second hash function on the first hash value and a pepper, and send the second hash value to the computing device.

Hashing values using salts and peppers

For computing nodes having a first programmable and comprising a first node and a second node, an update of the first node from the first programmable to a second programmable across an external network is initiated. In response to the update being interrupted, the first programmable is automatically reinstated on the first node by retrieving the first programmable from the second node across an internal network. The second node is automatically updated to the second programmable by retrieving the second programmable from the first node across the internal network in response to completion of the update of the first node to the second programmable.

Update of programmable for computing nodes

Example implementations relate to sequential resets of redundant subsystems. For example, in an implementation, a controller may receive a maintenance activity instruction and may perform the maintenance activity on the redundant subsystems. After performance of the redundant subsystems, the controller may sequentially reset each of the redundant subsystems. The controller may wait a random delay between sequential resets of the redundant subsystems.

Sequential resets of redundant subsystems with random delays

One embodiment is a method that segments a bus topology to increase addressable devices that can attach to a bus. Switching occurs between different segments on the bus having multiple bus segments linked together.

Segmenting bus topology

There is provided a system and method for remote management of a computer. The method includes establishing a connection between a remote console and a managed server. Additionally, the method includes detecting a change in the status of the connection and issuing commands to lock the managed server if a change in status of the connection is detected.

System and method for remote management of a computer

In at least some embodiments, a computer system includes a processor and a firmware storage medium in communication with the processor. The firmware storage medium stores a default image invoked during a boot process and selectively stores a customized image. If the customized image is stored by the firmware storage medium, the boot process selectively substitutes at least part of the default image with at least part of the customized image.

Firmware storage medium with customized image

Systems, methodologies, media, and other embodiments associated with managing memory health are described. One exemplary system embodiment includes logic for detecting and correcting single bit memory errors. The example system may also include logic for selectively making unavailable a memory location associated with single bit memory errors.

Managing memory health

In one embodiment, a first client device establishes a remote session between a remote computing device and the first client device. One or more subsequent client devices that attempt to establish a remote session with the remote computing device are re-directed to another computing device that serves as a host for the remote session.

Methods and systems for sharing remote access

A method to communicate provide server management information that emulates a floppy disk drive (FDD) with a management processor. This management processor operably couples to a multi-function integrated circuit having a FDD controller. Monitoring hardware and sensors operably couple to the management processor and write server management information to data files within the emulated FDD. Programs that utilize the server management information may then read this server management information.

Virtual mass storage device for server management information

In at least some embodiments, a system comprises an electronic device having an adjustable hardware inventory and control logic coupled to the electronic device. The control logic initially allocates a first amount of power to the electronic device based on predetermined maximum power needs of the electronic device and later allocates a second amount of power to the electronic device based on a determination of a true hardware inventory of the electronic device.

Methods and systems for allocating power to an electronic device

An apparatus for configuring a computer system is disclosed. The apparatus comprises a processor, a read only memory (ROM) coupled to the processor, and a management device coupled to the read only memory. During operation, the management device preferably receives at least some data from the ROM.

Method and apparatus for configuring a computer system utilizing a read only memory storing an option file containing selectable configuration options and a script file

An apparatus and method for dynamic suppression of spurious interrupts in a computer system. More specifically, there is provided a method that comprises providing a look-up table comprising source IDs and corresponding time delays for each of a plurality of interrupt lines, monitoring each of the plurality of interrupt lines, and updating the time delays in the look-up table based on the monitoring of the interrupt lines, and a system for implementing the method.

Method and apparatus for dynamic suppression of spurious interrupts

The disclosed embodiments relate to the field of remote server management. More particularly, the disclosed embodiments relate to providing secure communications in the context of remote server management. In an exemplary embodiment of the invention, a client computer uses an established encrypted communication channel to request secret data from a managed server. The managed server provides the requested secret data, which is used by both the managed server and the client computer to encrypt communications across a second communications link.

Method and apparatus for initiating strong encryption using existing SSL connection for secure key exchange

The invention is directed to a system and related method of allocating power in a rack mounted computer system where the individual servers are powered from a central power supply system. The structure includes a series of serial communication pathways coupling the servers and the individual power supplies in the power supply system. A series of chassis communication modules communicates with servers in its respective chassis, and relays messages to and from a power supply communication module, which is responsible for granting or denying permission for individual servers to allocate power. The disclosed system also envisions intelligent de-allocation of power, for example in the event of a failure of individual components of the central power supply system.
