Abstract: A first storage node is connected to a host by using a first network interface card of the first storage node, and is connected to a second storage node by using a second network interface card. The first storage node receives a data processing request from the host, wherein the data processing request carries a target storage address of to-be-processed data, determines the second storage node based on the target storage address of the to-be-processed data, and sends the data processing request to the second storage node by using the second network interface card, wherein the data processing request instructs the second storage node to process the to-be-processed data.

Abstract: A redundant array of independent disks (RAID) management method includes, when detecting that a component in a storage medium fails, recovering, based on a RAID policy, data stored in the failed component, saving the recovered data into a pre-defined redundant space of the RAID, and mapping an address of the failed component with the address of the redundant space, converting, according to the mapping, an address of to-be-accessed data comprised in an accessing request into an address within the redundant space, and accessing the to-be-accessed data from the redundant space according to the address within the redundant space.

Abstract: A data writing method includes: receiving a write command, where the write command carries a type of to-be-written data; determining, based on the type of to-be-written data, a type of storage area that is in an SSD and into which the to-be-written data is written, where the SSD includes a plurality of types of storage areas; determining, based on the type of storage area, a target storage area into which the to-be-written data is written; and writing the to-be-written data into the target storage area. In embodiments of this application, data processing efficiency can be improved.

Abstract: A solid state disk and a data moving method are disclosed. The SSD includes a storage medium and a control chip, where storage space of the storage medium is divided into at least two blocks for storing data, and the control chip includes: a service processing module sends a moving command to a moving module; and the moving module receives the moving command; read valid data from the source block according to the moving command, and perform ECC checking on the valid data; and write checked data into a blank page of the destination block. The SSD can control movement of data from a source block to a blank page of a destination block; compared with a data moving process in which read and write are separated, a path that data moving passes through is simple and reduce impact of the data moving process on performance of the SSD.

Abstract: A storage system, includes a controller and a solid state disk. The controller creates multiple segments in advance, selects a first die from the multiple dies, selects a first segment from the multiple segments, determines an available offset of the first segment, generates a write request, where the write request includes a write address, target data, and a data length of the target data, and the write address includes an identifier of a channel coupled to the first die, an identifier of the first die, an identifier of the first segment, and the available offset, and sends the write request to the solid state disk. The solid state disk receives the write request, and stores the target data according to the write address and the data length.
