A method and computer program product are provided for controlling the airflow direction through a device enclosure. A first device enclosure is positioned adjacent a second device enclosure, wherein both enclosures have an airflow pathway extending from the front to the back, and a fan for moving air through the airflow pathway, wherein the fan of the first device enclosure is a reversible rotary fan. The method automatically determines whether the first device enclosure is in a first orientation with its front facing in the same direction as the front of the adjacent second device enclosure or in a second orientation with the front facing in the same direction as the back of the adjacent second device enclosure. The airflow direction imparted by a reversible rotary fan is then controlled according to the determined orientation of the first device enclosure relative to the second device enclosure.

Water is circulated through a cooling system within a compute node to remove heat from a heat-generating component within the compute node. Water leakage from the cooling system is collected into a containment reservoir within the compute node. A rate of the water leakage is measured, a temperature of the compute node is measured, a rate of water evaporation from the containment reservoir is determined based upon the measured temperature, and the rate of water leakage is compared to the rate of water evaporation to determine whether water is accumulating in the containment reservoir. A period of time before the containment reservoir reaches a critical level may also be determined.

A server cloud contains multiple physical servers. A NIC controller device is on a first physical server in the server cloud. The NIC controller device establishes a maximum network bandwidth percentage for the first physical server in the server cloud. The maximum network bandwidth percentage is a percentage of a total network bandwidth capability designed for the first physical server. Response time for operational requests to one or more virtual machines on the first physical server changes beyond a predefined differential in response to the maximum network bandwidth percentage being reached. In response to the NIC controller device on the first physical server determining that the maximum network bandwidth percentage for the first physical server is exceeded, a cloud service hypervisor device moves one or more virtual machines on the first physical server to a second physical server in the server cloud.

An electronic device has a number of ports that have the same physical form factor and that are receptive to cable insertion. The electronic device also has visual indicators corresponding to the ports. Each visual indicator indicates at least link establishment when a cable has been inserted into its corresponding port and a link has been established. When a cable is removed from a port, the electronic device controls its corresponding visual indicator to identify the port as one from which cable removal has recently occurred.
