Abstract: A method for configuring a connection in a storage system is provided. A configuring device determines that the configuring device cannot communicate with a first control board, and identifies route information related to the first control board in a route information table. The route information is route information between an adapter card and the first control board. The configuring device modifies the identified route information by changing an address of the first control board in the route information to an address of a second control board.

Abstract: A method for configuring a connection in a storage system is provided. A configuring device determines that the configuring device cannot communicate with a first control board; searches a route information table for route information related to the first control board, wherein the route information is route information between an adapter card and the first control board, wherein the adapter card is connected to a north bridge of the first control board through a PCIe bus; modifies the searched out route information by changing an address of the first control board in the route information to an address of a second control board, and stores the modified route information in the route information table.

Abstract: Embodiments of the present technical solution relate to the technique field of storage, and disclose a server and a method for the server to access a volume. The method comprises: determining, from a first list, a block that needs to be accessed according to an access offset of a volume that needs to be accessed; determining, from a second list, a storage controller corresponding to the block that needs to be accessed according to the determined block; and sending a data reading request or a data writing request to the storage controller corresponding to the block that needs to be accessed to process. Embodiments of the present invention can reduce time delay when the data reading request or the data writing request of the server reaches the block that needs to be accessed.

Abstract: A method for implementing a disk array, and a method and apparatus for reading or writing data are provided in embodiments of the present invention. The method includes: creating logical partition regions, where each logical partition region corresponds to one controller in one controller group; recording a mapping relationship between the logical partition regions and the controllers in a controller mapping table; and allocating, chunklets for the logical partition regions from a physical disk that is managed by a controller in a controller group that is corresponding to each logical partition region, and recording a mapping relationship between the logical partition regions and the chunklets in a chunklet mapping table. In the present invention, a chunklet in a physical disk that is managed by a controller in the same controller group is set to corresponding to each logical partition region, so that an expansion operation is completed easily.

Abstract: A method and an apparatus for accessing a network file system (NFS) are disclosed. The method includes: receiving a first request message, which is sent by a user equipment (UE) to the NFS according to an available first file type; converting, according to a preset mapping relation, the first request message into a second request message capable of driving a second file type in the NFS, and sending the second request message to the NFS; receiving a first response message, which is based on the second file type and is sent by the NFS to the UE in response to the second request message; and converting, according to the preset mapping relation, the first response message into a second response message which is based on the first file type, and sending the second response message to the UE. With the present invention, the file system protocol can be converted, and the NFS is compatible with multiple operating systems.
