Data read-write control method and system based on hyper-converged storage system and terminal

Abstract

The invention discloses a data read-write control method and system based on a hyper-converged storage system and a terminal, relating to the technical field of data storage. Therefore, effective utilization of processing resources in the hyper-converged storage system is increased. The method comprises the following steps: searching corresponding virtual volume controllers in local nodes according to read-write requests when receiving the read-write requests at the local nodes, wherein the virtual volume controllers are used for controlling read-write operation of virtual volumes corresponding to virtual machines created in the hyper-converged storage system; sending requests for creating the virtual volume controllers in the local nodes to a manager if there is not any virtual volume controllers, wherein the manager is used for managing virtual volume controllers corresponding to all virtual volumes in the hyper-converged storage system; and enabling the virtual volume controllers tocontrol corresponding virtual volumes to perform corresponding read-write operation according to information fed back to the requests by the manager.

Description

technical field [0001] The present invention relates to the technical field of data storage, and in particular to a data reading and writing control method, terminal and system based on a hyper-converged storage system. Background technique [0002] Hyper-convergence is inspired by the construction of large-scale data centers based on software-defined technology. It combines virtualization technology and enterprise IT scenarios to realize scalable IT infrastructure for enterprises. Among them, virtualization technology integrates server clusters based on virtual machines, reducing It eliminates the complexities of storing, protecting, and managing data of all sizes. Moreover, in the hyper-converged system, a distributed architecture is used to store the data in the virtual volume. The virtual volume can be understood as the virtual storage identifier on the virtual machine, which is similar to the disk partition of the computer hard disk, and the data in the virtual volume c...

However, the existing method is to only use the same control host to receive all operation requests for reading, writing, repairing, and migrating data in the virtual volume. When the number of operation requests received by the control host in the same time period is very large , and these operation requests are in a high concurrency state, the control host needs to manage a large amount of operations, and the corresponding generated control information data volume is also very large. Therefore, the control host may be overloaded or fully loaded. The other hosts in the distributed architecture are under a small load or idle state, so the processing resources in the distributed architecture cannot be effectively used, resulting in waste of resources
