Abstract: A control system for a storage apparatus includes two input/output modules (IOMs), and two non-volatile memory (NVM) devices that are electrically connected to the IOMs, respectively, and that each store a firmware code. Each of the IOMs is configured to execute a firmware corresponding to the firmware code stored in the corresponding NVM device, and to enter an active mode or a passive mode after executing the firmware. The IOMs are configured such that when one IOM operating in the passive mode detects abnormal operation of the other IOM operating in the active mode, the one IOM sends, to the other IOM, the firmware code stored in the NVM device electrically connected to the one IOM, in order to update the firmware code in the NVM device electrically connected to the other IOM.

Abstract: A method for recording memory errors includes the following steps: upon detecting a current correctable error that occurred in a volatile memory device, determining whether a count value corresponding to the current correctable error exceeds a predetermined value; and when it is determined that the count value corresponding to the current correctable error thus detected does not exceed the predetermined value, sending update event information corresponding to the current correctable error to a BMC, in order for the BMC to record information of the current correctable error.

Abstract: A method is provided for adding a sensor monitoring feature of a newly-added sensor to a system monitoring feature provided by a baseboard management controller (BMC). The BMC stores a BMC firmware that contains a main program, a sensor library and a sensor data record. The BMC updates the sensor library to a target sensor library that includes identification information of the additional sensor, and functions used to execute the sensor monitoring feature of the additional sensor. By executing the main program, the BMC loads the target sensor library, and adds the identification information of the additional sensor to the sensor data record.

Abstract: A method is provided for optimizing fan speed control of a computer system that includes a fan unit, a temperature sensor, a control unit to control operation of the fan unit, and a disk storage unit. A forbidden range corresponding to a range for a fan speed is determined based on a relationship between fan speed and vibration of the disk storage unit. An optimized fan control table is generated based on a reference table relating to a relationship between ambient temperature and fan speed. The optimized fan control table is generated by making a part of the ambient temperature values in the reference table change to corresponding to a predetermined fan speed not smaller than a fan speed value corresponding to an upper limit of the forbidden range.
