Abstract: Embodiments of the disclosure are directed to a cabinet for storing server equipment. The cabinet includes a fan cover disposed over the cabinet and configured to secure a plurality of fan units, and a locking system for securing the fan cover. The fan cover has a channel disposed along a front edge of the fan cover. The locking system includes at least one T-bar and a bracket. The at least one T-bar includes a horizontal bar movably disposed within the channel, and a vertical bar extending generally perpendicularly to the horizontal bar from a first end of the vertical bar.

Abstract: A cache device includes a cache module, which comprises a sensor data access interface, a sensor data acquisition module and a driver library. The sensor data access interface receives a data request of back-end sensors from a front-end monitoring system. The sensor data acquisition module inquiries the sensors for the sensor data in accordance with the received request, receives and saves sensor data from the sensors, and replies the sensor data to the monitoring system through the sensor data access interface. The driver library includes at least one driver program, the sensor data acquisition module reads the sensors via executing the driver program, wherein, the driver library selects a corresponding communication protocol which is used by the inquired sensors for the executed driver program to use thereto.
