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...

Abstract

The invention relates to the field of computer storage, and discloses a storage resource organization implementation method and architecture in a cloud storage environment. Each storage controller node is connected to each other through an internal high-speed Internet network, and the storage resources of each storage node are uniformly addressed. The mapping relationship between logical disks and physical disks, including storage controllers, high-speed Internet, and back-end disk resources, provides a storage resource organization structure and method in a cloud storage environment. The use of this method and structure can greatly improve storage nodes. The aggregated bandwidth improves the performance and efficiency of the entire storage system, accelerates cloud storage customers’ access to storage resources, effectively improves the aggregated bandwidth of storage controller nodes in the cloud storage environment, increases the performance and storage efficiency of the cloud storage system, and has Strong scalability.

Description

technical field [0001] The invention relates to an organizational structure and realization of storage resources in the field of computer storage, in particular to the organizational structure and realization of storage resources in a cloud storage environment. [0002] technical background [0003] Cloud storage technology is a new network-based IT service value-added, usage and delivery mode, which is a combination of data sharing and service sharing. Cloud storage needs to store and manage EP-level data. How to organize the data in the storage disk is a problem that must be solved first. At the same time, the number of hosts also shows an exponential growth. Different hosts are responding to I / O processing requirements. The time, transmission bandwidth, and transmission granularity are quite different. At the same time, each node of the cloud storage system needs to realize unified storage and management of data. At present, the cloud storage system mainly adopts a struct...
