A method of building a large-scale virtual data center using a small number of servers

Abstract

The invention provides a method for building a large-scale virtual data center using a small number of servers, which belongs to the technical field of cloud deployment. The invention connects the leaf spines on each physical host using VxLAN technology to form a logical leaf spine, which is installed on each physical server All virtual machines on the server are connected to this logical leaf spine to form a virtual data center. Greatly speed up the development of cloud products.

Description

technical field [0001] The invention relates to cloud deployment technology, in particular to a method for building a large-scale virtual data center using a small number of servers. Background technique [0002] Now that the data center has been cloudified, how to verify the large-scale deployment of the cloud before deploying the cloud to the data center is a thorny issue, mainly for the following reasons: [0003] 1) The data center requires a lot of hardware resources, and few companies can afford these expensive resources, and use them only for experimental verification. [0004] 2) These hardware resources require a computer room and consume electricity. Few companies have such conditions. [0005] 3) Low-end hardware can only build a simple network, and the network is not easy to change and is not flexible enough. For example, when the leafspine network is changed from an L2 network to an L3 network, the configuration changes greatly. [0006] Leaf-spine is a data ...

Problems solved by technology

[0003] 1) The data center requires a lot of hardware resources, few companies can afford these expensive resources, and use them only for experimental verification

[0004] 2) These hardware resources require a computer room and consume electricity. Few companies have such conditions

[0005] 3) Low-end hardware can only build a simple network, the network is not easy to change, not flexible enough

[0009] Another way is to use OpenvSwitch and VxLAN to connect several servers to form a large logical bridge, and the virtual machines on all servers are hung on this large logical bridge, thus forming a large-scale virtual data center , but the problem is that it cannot simulate the network architecture of leaf spine, and cannot configure various networking methods, such as layer 2 access to leaf switches, leaf switches and spine switches layer 3 access

More complicated, Layer 3 access leaf switch
