Embodiment 1
[0030] A method for implementing storage resource organization in a cloud storage environment. Each storage controller node is connected to each other through an internal high-speed interconnection network, the storage resources of each storage node are uniformly addressed, and a mapping relationship between logical disks and physical disks is established.
Embodiment 2
[0032] On the basis of Example 1, the method flow is as follows:
[0033] After all controllers are initialized, the disk management function of the controller will map the local disk resources;
[0034] After the mapping is completed, uniformly address the entire disk resource, so that each controller can manage all storage resources in the storage system;
[0035] When the cloud storage client submits to create a network disk, the storage controller receives a request to create a new logical disk, and the controller makes the newly created logical disk evenly distributed in the entire uniformly addressed storage resource through physical-virtual disk mapping;
[0036] When receiving a cloud client write request, the controller writes corresponding data blocks on different controllers according to the mapping relationship between the logical disk and the physical disk, and the controller is responsible for IO splitting the data to be written;
[0037] When receiving the read...
Embodiment 3
[0040] A cloud storage environment storage resource organization structure is characterized in that it includes: a storage controller, a high-speed Internet, and a back-end disk resource, wherein:
[0041] The storage controller provides protocols to support disk management, and provides a front-end card and a back-end card. The front-end card is connected to the high-speed Internet, and the back-end card is connected to the back-end disk resources. The storage controller runs a dedicated storage system. Map and uniformly address the storage resources of each storage node. After uniformly addressing the global storage resources, map the physical storage space to the logical storage space, so that each storage resource created by the cloud client host is evenly distributed among the storage nodes. In fact, this mapping from physical to logical storage space is transparent to cloud client hosts;
[0042] High-speed Internet, providing low-latency, high-bandwidth network connecti...
