Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a network topology structure based on hybrid co-city dual activity in an embodiment of the invention.
As shown in fig. 1, a network topology structure based on mixed co-city dual activity, the network topology structure includes: the application layer consists of two virtualization platforms; the network layer consists of two core fiber switches, two fiber high-speed network devices and two IB high-speed network devices; the data storage layer consists of a traditional storage database cluster and an all-in-one storage database cluster.
The embodiment of the invention mainly solves the problem of alternating backup between two stations, and the two stations share the same application layer, the same network layer and the same data storage layer. The design for the application layer is executed by adopting a traditional scheme, and each of the two virtualization platforms is deployed with a virtual machine, so that a common virtual environment is built in the application layer and used for providing information technology resources required by application deployment.
Referring to fig. 2, fig. 2 is a specific schematic diagram of a network topology structure based on hybrid co-city dual activity in the embodiment of the present invention, and the network structure of each layer of fig. 1 may be expanded as follows:
in the embodiment of the present invention, the network layer includes two network environments, i.e., a traditional optical fiber high-speed network and an IB high-speed network, and the two network environments are configured by a core optical fiber switch to perform allocation tasks, which is specifically expressed as follows: aiming at an application system with low service performance requirement, relevant data of the application system is stored in a traditional optical fiber high-speed network environment with relatively low performance and low manufacturing cost; for application systems with high service performance requirements, relevant data is stored in an IB high-speed network environment with high performance.
Specifically, each core fiber switch of the two core fiber switches is connected with each virtualized platform of the two virtualized platforms, and is used for executing service splitting, namely complexity identification and corresponding channel transmission allocation are performed according to the unified service distributed by the application layer. It should be noted that, the two core fiber switches are set to implement information interaction with the same virtualization platform in the implementation process, and the reason is that any one virtualization platform can provide resource services for all application systems. In addition, a network connection relationship exists between the two core fiber switches, and when any one core fiber switch has a network transmission blocking fault or a body operation fault, the network connection relationship can be switched to the other core fiber switch for cooperation operation.
Specifically, each of the two optical fiber high-speed network devices includes an optical fiber access switch, and the optical fiber access switch is connected with a corresponding core optical fiber switch, and is used for converging service data with relatively low performance.
Specifically, each of the two IB high-speed network devices includes a long-distance IB switch and a local IB switch; the long-distance IB switch is connected with the corresponding core fiber switch and is used for converging service data with relatively high performance and creating long-distance transmission conditions; and the local IB switch and the long-distance IB switch realize a connection relation through an IB network and are used for reading the service data with relatively higher performance and creating local transmission conditions. Generally, the two long-distance IB switches corresponding to the two IB high-speed network devices have an IB network connection relationship, and when any one long-distance IB switch judges that a local IB switch connected with the two long-distance IB switches has a data transmission failure, all the read service data can be transmitted to the other long-distance IB switch, so that all the service data can be responded normally in time.
In the embodiment of the present invention, the conventional storage database cluster includes two sets of database servers, and each set of database server in the two sets of database servers is connected to a corresponding optical fiber access switch, so as to store the service data with relatively low performance and execute subsequent low-level service docking, which is equivalent to implementing a conventional storage dual-activity solution based on storage virtualization. Each database server in the two groups of database servers comprises a main database server and a standby database server, so that service data loss caused by any server abnormal faults can be timely handled.
In the embodiment of the invention, the all-in-one machine storage database cluster comprises two groups of all-in-one machine database servers, and each group of all-in-one machine database server in the two groups of all-in-one machine database servers and the corresponding local IB switch realize a connection relationship through an IB network, so that the all-in-one machine database server is used for storing the service data with relatively higher performance and executing subsequent high-level service butt joint, which is equivalent to implementing the traditional database all-in-one machine dual-activity solution based on a high-speed IB network. Each of the two groups of all-in-one machine database servers comprises a main all-in-one machine database server and a standby all-in-one machine database server, and a Flash high-speed Flash memory and an SSD high-performance solid state disk are integrated in any one of the all-in-one machine database servers so as to improve the storage and response performances of the all-in-one machine database servers.
The network topology structure based on the mixed same-city dual-activity provided by the embodiment of the invention completes the junction of the traditional pipeline network and the IB high-speed network through the core optical fiber switch and the classified storage of data by utilizing the division of the data storage layer, can realize the fusion deployment and independent implementation between the storage dual-activity solution based on the storage virtualization and the database all-in-one dual-activity solution based on the high-speed IB network, provides a proper response environment for any type of application system to ensure a good running state, simultaneously furthest reduces the capital cost of enterprises for developing the same-city dual-activity construction, and has good practical value.
