Abstract: This application discloses a power consumption management method. Resources such as computing resources or communication resources in the computer system include a first resource area and a second resource area. In addition, a resource provided in the first resource area includes a computing resource or a communication resource, and is used to support a workload in the first resource area. When a workload migration condition is met, the computer system may migrate a workload in the first resource area to the second resource area. In this case, workloads in the first resource area are reduced, or there is no workload in the first resource area.

Abstract: The present disclosure discloses a method for determining a drive letter, including: obtaining a number of a port connecting a redundant array of independent disk RAID controller to an exchange chip and a location number, of a disk, meeting a report condition in each RAID group under the control of the RAID controller, where the location number, of the disk, meeting the report condition is a location number, of a disk, on a preset location after location numbers of all disks included in each RAID group when each RAID group is configured, are sorted according to a preset sequence; and determining a drive letter corresponding to each RAID group according to the number of the port connecting the RAID controller to the exchange chip and the location number, of the disk, meeting the report condition in each RAID group.

Abstract: In a subrack with multiple boards, in order to enable a server board and at least one client board of the multiple boards to access a same storage device, an embodiment server board acquires, physical information of at least one physical storage device. Then the server board sends a client board the physical information to enable the client board to establish a virtue storage device and receives a first request for accessing the virtual storage device sent from the client board. The server board convertes the first request for accessing the virtual storage device into a second request for accessing the physical storage device, and sends the second request for accessing the physical storage device to a storage controller connected to the physical storage device in order to enable the storage controller to send relevant data to the client.
