A technique includes a baseboard management controller receiving, from a requestor, a request for a security function to be performed, where the request is directed to a physical security device other than the baseboard management controller. The technique includes, the baseboard management controller responding to the request to emulate a response to the security device to the request.

Emulating physical security devices

A system is provided, which manages, by a microcontroller internal to a fan installed in a server, power data associated with the fan, wherein the fan includes two pins configured to communicate signals based on an inter-integrated circuit (I2C). During operation of the fan, the microcontroller measures a first and second amount of power consumed by the fan at a first and second time. The microcontroller transmits, via the two pins, the information to a system management entity which monitors and manages the server, wherein the system management entity controls a speed of the fan in response to receiving the measured power data and based on a net power comprising a difference between a total amount of power consumed by the server and an amount of power consumed by the fan.

Fan enhancements to improve server performance and quality

An apparatus includes a host and a baseboard management controller. The baseboard management controller includes a semiconductor package; and the semiconductor package includes a memory, a security hardware processor; and a main hardware processor. The main hardware processor causes the baseboard management controller to serve as an agent that, independently from the host, responds to communications with a remote management entity to manage the host. The security hardware processor manages the storage of a secret of the host in the memory.

Managing storage of secrets in memories of baseboard management controllers

Some examples described relate to securing a memory device of a computing system. For instance, a method may comprise comparing a command for the memory device to each command in a list of commands. The command is accepted when the command matches an authorized command in the list of commands. The accepted command is issued to the memory device.

Securing a memory device

A process includes an application layer of a host of a computer platform using a smart network interface card (NIC) of the computer platform to provide an input/output (I/O) service for the application layer. The I/O service includes a service that is associated with a cloud operator domain; the smart NIC is installed in a connector; and the application layers associated with a cloud tenant domain. The process includes a baseboard management controller of the smart NIC managing the computer platform. Managing the computer platform includes the baseboard management controller managing the host; the baseboard management controller managing components of the smart NIC other than the baseboard management controller; and managing the host includes the baseboard management controller communicating with the host via the connector to control a system power state of the computer platform.

Server network interface card-located baseboard management controllers

A process includes a port of a bridge providing a reference clock signal to a first end of an interconnect extending between the first port and a network interface controller. The reference clock signal propagates over the interconnect to provide, at a second end of the interconnect, a delayed reference clock signal at the network interface controller. Pursuant to the process, the bridge senses a timing of the delayed reference clock signal. The process includes communicating management traffic between a network interface of a baseboard management controller and the network interface controller via the interconnect. The communication of the management traffic includes the port, responsive to the sensing of the timing of the delayed reference clock signal, synchronizing communication of data with the first end of the interconnect to the delayed reference clock signal.

Communicating management traffic between baseboard management controllers and network interface controllers

Examples described herein relate to consumption monitoring device and method for changing a client for its use of a networked resource. The consumption monitoring device may receive information regarding an out-of-band (OOB) performance parameter from a manageability controller corresponding to a networked resource subscribed by the client. The consumption monitoring device may determine a resource consumption metric corresponding to the networked resource for the client based at least on the information regarding the OOB performance parameter received from the manageability controller. The client may be charged based on the resource consumption metric.

Consumption monitoring device and related method for networked resources

An apparatus can include a fan including a control pin. The fan may receive a pulse width modulated (PWM) signal at the control pin. The fan may further control a speed of the fan based on a duty cycle of the PWM signal when the PWM signal is in a first range and, responsive to the duty cycle of the PWM signal being in a second range, transmit information corresponding to the fan to an external controller.

Example implementations relate to system and method of managing transitioning of a computing system to a power-on state from a standby-power state. The computing system includes a manageability controller, an initialization controller, an auxiliary device, and a processor. In such examples, the manageability controller may first determine an initialization status of the auxiliary device from a data corresponding to the auxiliary device, when the computing system is transitioning from the standby-power state to the power-on state. In one or more examples, the initialization status may include the auxiliary device in an initialized stage or a non-initialized stage. Later, the manageability controller may direct the initialization controller to delay the transitioning of the computing system from the standby-power state to the power-on state, in response to determining that the initialization status of the auxiliary device is in the non-initialized stage.

Managing transitioning of computing system to power-on state from standby-power state

A processor executes firmware to write control data describing transfer descriptors for a bus protocol engine to an address that is associated with a transfer descriptor buffer for the bus protocol engine. The bus protocol engine performs an operation according to the transfer descriptors with a slave device; the processor is part of a first semiconductor package; the bus protocol engine is part of a second semiconductor package other than the first semiconductor package; and the address corresponds to a memory of the second semiconductor package. A first physical interface of the first semiconductor package communicates with a second physical interface of the second semiconductor package to direct the control data to the memory.

Directing control data between semiconductor packages

An example computing system includes a baseboard management controller (BMC), a motherboard, and a daughterboard communicatively coupled to the motherboard. The BMC includes a serial interface. The daughterboard includes a universal asynchronous receiver/transmitter (UART) terminal, a bridging chip, and a microcontroller communicatively coupled to the BMC via the bridging chip. The BMC establishes a serial connection, through the serial interface and the UART terminal, with the microcontroller.

Serial connection between management controller and microcontroller

An arrangement for securing a memory device of a computing system in which a memory access command is compared to each command in a list of commands. The command, with specified attributes, is authenticated when the command and its attributes match an entry in the list of commands. Following authentication, the command is evaluated according to usage and behavior metrics in order to identify and prevent unauthorized or malicious access of the memory device. If no violation of usage or behavior metrics is detected, the command may be issued to the memory device for execution.

Securing a memory drive

A system and method for a computing device having a processor, a memory module including volatile memory for random access memory (RAM), and an integrated circuit to intercept an error signal from the processor, the intercept delaying a system shutdown of the computing device. Firmware is executed by the processor to copy contents of the volatile memory to a non-volatile memory during the delay of the system shutdown.

Data copy to non-volatile memory
