Abstract: In a data access method, a network device receives access requests sent by a plurality of clients connected to the network device, and sends the access requests to an access queue of a storage unit. The storage unit executes the access requests in the access queue, and returns processing results of the access requests of the plurality of clients. The network device returns the processing results that are of the access requests and that are returned by the storage unit to the clients corresponding to the access requests.

Abstract: A storage system comprises a host, a first control device, a second control device, and a storage drive that has a physical connector A and a physical connector B for connecting to the first control device and second control device, respectively. When the storage drive is configured to operate in first working mode, it provides a shared storage space to be accessed by both the first control device and the second control device. When the storage drive is configured to operate in a second working mode, it provides a first storage space for access by the first control device and a second storage space for access by the second control device.

Abstract: A redundant data calculation method and apparatus. The method is applied to the redundant data calculation apparatus including a processor and a redundant data calculation unit. In the method, after obtaining to-be-processed data, the processor stores the to-be-processed data in cache space of the redundant data calculation unit. The redundant data calculation unit obtains the to-be-processed data from the cache space and performs calculation for checking the to-be-processed data to obtain redundant data corresponding to the to-be-processed data.

Abstract: A chip module has a plurality of first ports, at least some or all of the first ports are first selection ports, and each first selection port may act as a write port or a read port. The chip module further includes a first control module. The first control module controls, based on a transmit/receive requirement of the chip module, the first selection port to be switched to a read port or a write port, to match the transmit/receive requirement of the chip module. The first selection port may selectively act as a read port or a write port, so that switching can be performed based on an operating state of the chip module, increasing a read/write bandwidth. The first control module controls an operating state of the first selection port, to flexibly adjust a quantity of read ports and a quantity of write ports of the chip module.

Abstract: A first storage node communicates with at least one second storage node. A physical disk included in the at least one second storage node is mapped as a virtual disk of the first storage node. The method may include: receiving a first write request, where the first write request carries first to-be-written data; striping the first to-be-written data to obtain striped data, and writing the striped data to a physical disk and/or the virtual disk of the first storage node; and recording a write location of the striped data. For example, the technical solution may be applied to a storage system that includes an NVMe SSD.
