Abstract: A bare-metal server of a cloud storage management system comprises a system-on-chip (Soc) and a processor. The SoC receives a volume attaching request sent by a public cloud management component of the management system. The volume attaching request includes an identifier of a system volume storing a file for starting an operating system of a bare-metal server of the management system. The SoC stores the identifier of the system volume based on the volume attaching request. When the bare-metal server of the management system is started, the bare-metal server uses the identifier of the system volume to the system volume, and starts an operating system by means of the SoC accessing the system volume.

Abstract: A storage network element discovery method and an apparatus, where the method includes broadcasting or multicasting, by a control network element, a heartbeat message to at least one storage network element, where the heartbeat message includes address information of the control network element, receiving, by the control network element, a response message returned by at least one storage network element according to the heartbeat message, and determining an accessible storage network element according to the response message, where the response message includes network parameter information of the corresponding storage network element. Therefore, in a storage array, by broadcasting or multicasting a heartbeat message and according to a reply from a storage network element, a control network element may determine a storage network element that can be accessed by the control network element.

Abstract: A direct memory access (DMA) transmission control method and apparatus, where the method includes selecting a target channel for the target DMA task according to a priority corresponding to the target DMA task when a DMA transmission request for transmitting data of a target DMA task is received, querying a task type and a priority of another DMA task that has occupied a channel and a task type of the target DMA task when the other DMA task exists on the DMA channel, comparing the task type and the priority of the other DMA task that has occupied the channel with the task type and the priority of the target DMA task, and controlling data transmission on the DMA channel according to a comparison result. Hence, the urgent DMA task can be preferentially processed.

Abstract: According to a storage system, method, and apparatus for processing an operation request provided by embodiments of the present invention, a controller directly encapsulates a SCSI protocol operation request into an Ethernet operation request packet at the MAC layer instead of using the TCP/IP protocol layer and a disk enclosure decapsulates the Ethernet operation request to obtain the SCSI protocol operation request and sends the SCSI protocol operation request to a target disk, thereby reducing layers of encapsulation, reducing a processing delay of the storage system, and improving performance of the storage system.
