Problems solved by technology

However, there are differences in the network connection bandwidth between different data centers and the processing capabilities of the storage systems in the data centers, which will cause the cloud storage platform to be unable to provide users with real-time and reliable data services like traditional enterprise-level storage systems
For example, the system will encounter sudden peak access requests, resulting in local or global network congestion; in addition, the reliability of the WAN link is not high, and the service quality of the platform cannot be guaranteed

Embodiment Construction

[0019] A hierarchical architecture is used to manage multiple data centers of different levels on the WAN. like figure 1 As shown in the figure, the first-level data center usually sets the computer room in the center of the area to facilitate network coverage. The first-level data center deploys two core switches at the network boundary to aggregate the dual uplinks of each second-level data center to avoid single point of failure.

[0020] The secondary data center is a branch of the primary data center, and the computer room is usually built in the center of the secondary area. The secondary data center connects to the primary data center with two optical fiber dedicated lines to realize high-speed data exchange between business systems. The two dedicated lines can not only increase the bandwidth through aggregation, but also realize link redundancy.

[0021] The third-level data center is a further diversion of the second-level data center. The computer room is built o...

Abstract

The invention provides a cloud storage platform with QoS guarantee. The cloud storage platform comprises four levels of data centers, and virtual data centers containing a plurality of levels of the data centers are divided according to geographic positions; duplicates of the same data are cached on different levels of data center storage systems in the virtual data centers; the first-level data center is provided with a global resource controller which controls data access loads of services of different QoS levels by allocating network and storage system resources cloud-stored in all data centers; all other levels of the data centers are provided with partial resource controllers so that network flow of the data centers and storage system load conditions can be reported to the global controller in real time; a user downloads data from the fastest data center through an API of the cloud storage platform. By means of the cloud storage platform, the balance condition of the network flow and the storage system load of cloud storage platform of a wide area network is obviously improved, the access speed of the user is improved, and the overall throughput rate of the system is improved.

Description

technical field [0001] The invention relates to the technical field of computer information management, in particular to a wide area network distributed cloud storage system, and in particular to its system connection structure and resource scheduling method. Background technique [0002] With the continuous popularization of cloud computing technology, users have higher requirements for the data quality of service (QoS) of cloud storage platforms. Cloud storage platforms are usually built based on multiple data centers on a wide area network. However, there are differences in the network connection bandwidth between different data centers and the processing capabilities of the storage systems in the data centers, which will cause the cloud storage platform to be unable to provide users with real-time and reliable data services like traditional enterprise-level storage systems. For example, the system will encounter sudden peak access requests, resulting in local network or...
