Abstract

The invention provides a command processing method and device. The command processing method and device are applied to storage nodes in cluster storage. Each storage node in the cluster storage receives and transmits commands through a back-end network, a transmitting end concurrently transmits a plurality of commands with an association relationship, and a receiving end sequentially processes theplurality of commands with the association relationship according to a processing sequence number included in each command. Due to the adoption of a concurrent sending mode, the utilization rate of back-end network resources can be effectively improved; the receiving end can sequentially process the plurality of received commands according to the processing sequence number included in each command without waiting for the transmitting end to transmit the next command after one command is processed, so that the processing performance of the storage node can be effectively improved. In conclusion, the operation efficiency of the whole cluster storage can be effectively improved.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a command processing method and device. Background technique [0002] Cluster storage refers to a storage cluster composed of several general-purpose storage devices, which can provide stronger storage performance, reliability, and utilization than a single storage device. Cluster storage includes front-end network, storage nodes and back-end network. The server can access the storage devices in the cluster through the front-end network to store or read data. Each storage device can exchange information through the back-end network to realize management, data synchronization and remote access. [0003] Information exchange between storage devices is realized through commands, and the involved commands mainly include management commands, write commands, and read commands. In some application scenarios, there is a relationship between commands. For example, if a...
