Abstract: The present application relates to a storage device operation control method, a storage device, and a management node. The method includes: receiving at least one request sent by at least one management node; and when one of the at least one request is a permission application request, determining, according to a current permission status, whether to assign operation permission to a management node that sends the permission application request; or when one of the at least one request is an operation request, determining, according to a current permission status, whether a management node that sends the operation request has operation permission, and performing an operation according to the operation request when the management node that sends the operation request has the operation permission. This avoids a conflict caused by simultaneously performing an operation on a storage device by multiple management nodes, and prevents successive serial operations from being interrupted.

Abstract: A method for implementing NVMe over fabrics includes generating, by a terminal, a NVMe instruction, where the NVMe instruction indicates a data read operation or a data write operation. The method further includes sending, by the terminal by using remote direct memory access (RDMA), the NVMe instruction to a submission queue (SQ) that is stored in a server. When the NVMe instruction indicates the data read operation, the method includes receiving, by the terminal by using the RDMA, to-be-read data sent by the server. Alternatively, when the NVMe instruction indicates the data write operation, the method includes sending, by the terminal, to-be-written data to the server by using the RDMA. The method further includes receiving, by the terminal, an NVMe completion instruction sent by using the RDMA by the server; and writing, by the terminal, the NVMe completion instruction into a completion queue (CQ) that is set in the terminal.
