Abstract: The following description is directed to dynamically adjusting a refresh rate. In one example, a method can include determining a rate of memory errors, and dynamically adjusting a refresh rate of a memory based at least partially on the determined rate of memory errors.

Abstract: Methods and systems for detecting passive failure in a cooling system that employs two or more actuators for moving a fluid can include outputting a control signal to cause the movement of an actuator, where the control signal is associated with an expected rate of movement of the actuator; receiving information concerning an output signal from the actuator that is associated with an actual rate of movement of the actuator; and comparing the actual rate of movement of the actuator with the expected rate of movement of the actuator. A passive failure can be detected when the actual rate of movement of the actuator falls outside a nominal range that is based on the control signal.

Abstract: Techniques and solutions for automatically filtering network broadcast traffic are described. For example, network broadcast traffic can be automatically filtered by turning broadcast filtering on and off (e.g., as a continuous strobe pattern that alternates enabling and disabling of broadcast filtering). For example, a computing device (e.g., via a network interface or management controller of the computing device) can automatically enable network broadcast traffic filtering during a first time period (e.g., a four second time period) and disable network broadcast traffic filtering during a second time period (e.g., a one second time period). A computing device can also automatically enable and disable network broadcast traffic filtering according to an on-off pattern (e.g., based on various criteria, such as network queue size, broadcast traffic volume, etc.).

Abstract: A method and system for monitoring performance of an input/output (“I/O”) processor in a server associated with a computing system, such as an intelligent I/O (“I2O”) compliant computer system. A virtual adapter in the I/O processor monitors messages passing through the I/O processor to produce message data. An I/O monitor associated with each server in the computing system constructs a server communications model for its respective server using the message data provided by each of the virtual adapters associated with the I/O processors in the server. The I/O monitor may also collect information regarding non-I2O devices. An I/O user interface builds a computing system communications model using the server communications models provided by the respective I/O monitors in each of the computing system's servers.
