Abstract: When a baseboard management controller (BMC) is used to control a fan speed of a fan unit of a server by executing a firmware with fan parameter data stored in one temporary storage region, the fan parameter data is updated by receiving fan parameter update data and storing the fan parameter update data in another temporary storage region, and updating the fan parameter data using the fan parameter update data after determining that the received fan parameter update data is valid.

Abstract: A storage enclosure connected to a server via an external network and includes a network switch, an expander that is connected to the network switch and that is configured to generate enclosure data that supports a format conforming with SCSI Enclosure Services, and a board management controller (BMC) that is connected to the network switch and the expander. The BMC is configured to translate the enclosure data into enclosure translating data that supports a Redfish® format. The expander is configured to, after generating the enclosure data, transmit the enclosure data through the network switch to the BMC via an internal network. The BMC is configured to translate the enclosure data into the enclosure translating data, and to transmit the enclosure translating data to the network switch. The network switch transmits the enclosure translating data to the server through the external network.
