A data processing method and a storage apparatus are disclosed. The data processing method includes: receiving, by an NVMe storage device, an NVMe write command sent by a host, where the NVMe write command carries a key and a value pointer, the value pointer points to first storage space, and the first storage space is used to store a value; obtaining, by the NVMe storage device, the key from the NVMe write command and a value length, and allocating second storage space to the value according to the value length, where the second storage space is in the NVMe storage device; and obtaining, by the NVMe storage device, the value from the host, and storing the value in the second storage space.

Data processing method and NVMe storage device

A data processing system and method, and a corresponding apparatus, where the data processing system includes a controller and at least two storage nodes. The controller is configured to receive, using a first coupling between the controller and a host, an operation request received from the host, where the operation request includes an identity of target data and an operation type, determine at least one target storage node from the at least two storage nodes according to the identity of the target data, and send an instruction message to the at least one target storage node using a second coupling to the at least one target storage node, where the at least one target storage node is configured to send the target data to the host or obtain the target data from the host according to the instruction message.

Method, apparatus, and data processing system including controller to manage storage nodes and host operations

This application describes a method, a system, and a related device for network attached storage (NAS) data access. The method includes receiving, by a NAS client, an access request message, and determining an operation object according to information about to-be-accessed target data in the access request message, where the operation object includes a directory and/or a file to which the target data belongs. The method may also include generating a first direct memory access file system (DMAFS) packet according to a format described by using a preset file system type, where the preset file system type is used to describe a format of a DMAFS packet. Furthermore, the method may include sending the first DMAFS packet to an acceleration apparatus, so that the acceleration apparatus converts the operation object and an operation type that are in the first DMAFS packet into NFS data, and encapsulates the NFS data into a network protocol packet and sends the network protocol packet to a NAS server.

Method, system, and related device for NAS data access

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.

Method for implementing NVME over fabrics, terminal, server, and system

A data processing method and a storage apparatus are disclosed. The data processing method includes: receiving, by a non-volatile memory express (NVMe) storage device, an NVMe write command sent by a host, where the NVMe write command carries a key and a value pointer, the value pointer points to first storage space, and the first storage space is used to store a value; obtaining, by the NVMe storage device, the key from the NVMe write command and a value length, and allocating second storage space to the value according to the value length, where the second storage space is in the NVMe storage device; and obtaining, by the NVMe storage device, the value from the host, and storing the value in the second storage space.

The present invention relates to the field of communications, and in particular, to a method and a system for dynamically upgrading a chip and a baseboard management controller. The method includes: obtaining an upgrade file that is used for upgrading a chip; upgrading, based on the upgrade file, data in a flash memory that is used for storing data of the chip, and not performing a reset operation on the chip at this time; and when it is acquired through detection that the state of a service system that is connected to the chip is a service idle state, replicating the upgraded data in the flash memory to a random access memory in the chip, and performing a reset operation on the chip. According to the present invention, the availability and maintainability of the system are improved.
