Problems solved by technology

Because the control units 104_1 - 104_N need to have a certain degree of computing power, the production cost of the adapters 102_1 - 102_N is quite expensive, especially when the number of the adapters 102_1 - 102_N included in the storage system 10 increases, the cost of the storage system 10 will increase. will increase

Embodiment Construction

[0027] Please refer to figure 2 , figure 2 It is a schematic diagram of a software-defined storage system 20 according to an embodiment of the present invention. The software-defined storage system 20 can receive a command CMD from a client and operate on the command CMD. It includes a load balancing unit 200 , adaptation units 202_1 ˜ 202_N and a control unit 204 . The load balancing unit 200 is used for dispatching the command CMD to the adaptation units 202_1˜202_N. The command CMD is a small computer system interface (Small Computer System Interface, SCSI) command, which includes a target information, and is used to instruct the software-defined storage system 20 to perform operations such as reading and writing the target data corresponding to the target information , and the target information corresponds to a virtual target vTGT_y among the virtual targets vTGT_1 ˜ vTGT_M of the software-defined storage system 20 . In general, the adaptation units 202_1˜202_N can f...

Abstract

A storage method utilized in a software defined storage (SDS) system is disclosed. The SDS system includes a load balancer unit, a control unit and a plurality of adaptor units. The plurality of adaptor units corresponds to a plurality of virtual targets. The storage method includes the load balancer unit sending a command to the plurality of adaptor units after the SDS system receives the command; the control unit generating a matching information according to characteristics of the plurality of virtual targets, and sending the matching information to the plurality of adaptor units; and a first adaptor unit of the plurality of adaptor units forwarding the command to the first virtual target according to the matching information and the command, and the SDS system performing operation on a first virtual target. The storage method may reduce the production cost of the SDS system.

Description

technical field [0001] The present invention refers to a storage method and a software-defined storage system, in particular to a storage method and a software-defined storage system that reduce the production cost of the storage system. Background technique [0002] Facing the advent of the Big Data era, the capacity required for storage devices will become larger and larger. In traditional storage systems, it often takes several weeks to expand storage devices, which is quite time-consuming, and compatibility issues between different brands of storage devices need to be resolved. The software-defined storage system separates the storage control function of the storage device from the storage hardware device, such as hard disk array (Redundant Array of Independent Disks, RAID) level setting, data volume management, data protection, data replication, and data snapshot and other functions, and transfer the storage control function to be executed by external software. In this...
