Systems and methods in accordance with various embodiments of the present disclosure provide secure handling of messages at a hardware-protocol level using a logic device on a server. Various embodiments provide approaches for filtering messages on various buses, such as SSIF, SMBus, PMBus, I2C, and SPI, within a server or a computer. Embodiments may include a policy engine through which message handling logic applied to a given bus or buses may be implemented. A message is compared to one or more policies. The message is allowed to be transmitted to a baseboard management controller based on the one or more policies and a type of message.

Secure message handling

Power systems and methods for supplying direct current power to a server rack via a power shelf assembly that includes multiple power supply units (PSUs) and a power shelf controller (PSC) that ensures a correct configuration of PSUs, backup battery units (BBUs), and connection components using a power shelf configuration record. Upon a boot cycle of the PSC, the configuration identified in the power shelf controller is compared to an actual configuration of the components being connected between a server rack and the power shelf assembly to avoid providing power too soon and causing an overload of components for the server rack.

Power control based on power controller configuration records

An assembly for containing and detecting leaks from a coolant line includes a basin with side and end walls, and at least one U-shaped cavity in an end wall for receiving a coolant line of a liquid cooling system. A bottom of the basin includes at least one sloped interior surface arranged to divert water in the basin to a local low point, where a sensor is positioned and operable to detect liquid in the collection basin. A leak detection system can employ a leak detection assembly to detect and/or locate a leak.

Leak detection and containment for liquid cooled computing

A management controller may request units of diagnostic information from a BIOS of the management controller's host computing device. The management controller may trigger an interrupt, in response to which the BIOS, by the execution of a processor of the host, may cause the diagnostic information to be copied to a video memory of the management controller. Upon the completion of the interrupt handler, a graphics controller of the management controller may cause the diagnostic information to be transferred to a non-volatile memory, and transferred out-of-band to a client device.
