Abstract: In some examples, a system includes a processor, a management controller; and a programmable device to provide input/output (I/O) expansion emulation to support communication with a plurality of I/O devices of a subsystem coupled to the system, where the programmable device provides a plurality of virtual registers as part of the I/O expansion emulation, the virtual registers associated with respective I/O devices of the plurality of I/O devices. The processor writes a value to a first virtual register of the plurality of virtual registers to trigger an output event relating to a first I/O device of the plurality of I/O devices at the subsystem. The management controller reads the first virtual register and, in response to the value written to the first virtual register, interact with the subsystem to issue the output event relating to the first I/O device at the subsystem.

Abstract: 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.

Abstract: 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.

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.

Abstract: 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.

Abstract: 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.
