The features and implementations of the present disclosure are described in detail below with reference to the drawings.

Please refer to "Figure 1" for a block diagram of the server system disclosed herein. The server system 100 of this embodiment can run a cloud operation system (cloud OS), and is, for example, a container data center (Data Center) that provides Infrastructure as a Service (IaaS). ). The server system 100 includes a plurality of nodes 110_1 110 110_N, a switch unit 120, a database 130, and a control unit 140 and a router 150, where N is a positive integer greater than one.

In this embodiment, a plurality of nodes (for example, nodes 110_1 110 110_3) may be regarded as a set, and for example, a space accommodated by these nodes is defined as a zone 160_1. It can be seen that the nodes 110_1~110_N of the present embodiment can form a plurality of regions 160_1~160_M, where M<N. Also, a plurality of regions (for example, regions 160_1 to 160_2) can be regarded as a set, and for example, a space accommodated by these regions is defined as a rack 170_1. It can be seen that the regions 160_1~160_M of the present embodiment can form a plurality of cabinets 170_1~170_L, where L<M.

For convenience of description, only the cabinet 170_1 has regions 160_1~160_2, the region 160_1 has nodes 110_1~110_3, the cabinet 170_L has regions 160_M-1~160_M, and the region 160_M has nodes 110_N-2, 110_N- 1, 110_N, that is, taking 3 nodes in each area and having 2 areas in each cabinet as an example, but the disclosure is not limited to the foregoing implementation manner, and may actually be performed according to the volume of different cabinets and areas. The corresponding adjustment.

The switch unit 120 is coupled to the nodes 110_1 110 110_N. In this embodiment, the switch unit 120 may further include a plurality of switches 121_1~121_N, and the switches 121_1~121_N are coupled to each other and coupled to corresponding nodes for performing the nodes 110_1~110_N. Data transfer and information exchange.

There are multiple configuration policies in the repository 130. In this embodiment, the configuration policy may include system security priority, system efficiency priority, download priority, upload priority, and upload priority. The configuration policy can be preset for the server system 100 to be preset in the database 130, or the server system 100 can provide a graphical user interface (GUI) for the user to create another user. Custom configuration policy. That is to say, users establish different priority configuration strategies according to their needs.

For example, the user can set the system efficiency priority, the download priority, and the upload priority to "high", "medium", and "low", so that the server system 100 can set the virtual machine configuration manner accordingly. In addition, the user-defined configuration policy can also include "system efficiency priority, upload priority, download priority." For example, when the configuration policy is "high, high, high", the system efficiency priority, upload priority, and download priority are both "high", that is, the virtual machine in the virtual cluster requires a large amount of computing data, and Virtual clusters require a large amount of external data communication.

When the configuration policy is "Medium, Medium, and Medium", it indicates that the system efficiency priority, upload priority, and download priority are both "medium", that is, the virtual machine in the virtual cluster needs appropriate computing data, and the virtual cluster needs to be appropriate. External communication. When the configuration policy is "low, low, low", it means that the system efficiency priority, upload priority and download priority are both "low", indicating that the virtual machine in the virtual cluster has very small amount of computing data, and the virtual cluster is rarely External communication.

The control unit 140 is coupled to the switch unit 120 (for example, the switch 121_1) and the database 130. In this embodiment, after the server system 100 is configured, the control unit 140 receives the configuration command, for example, by the user through the graphical user interface, and obtains the configuration policy according to the configuration command. As a selection configuration policy, according to the foregoing selection configuration policy, a plurality of virtual machines (VMs) of at least one virtual cluster (VC) are allocated to the corresponding nodes 110_1 110 110_N, so that the server system 100 It works normally.

Next, the control unit 140 collects related information of the virtual machine of the aforementioned virtual cluster. The information related to the virtual machine includes the amount of communication between the virtual machines, the amount of data transmitted by the virtual machine, and the amount of data received by the virtual machine. Then, the control unit 140 analyzes the related information of the virtual machine to obtain the virtual cluster feature corresponding to the virtual cluster, and then correspondingly selects the new configuration policy from the plurality of configuration policies in the database 130 according to the virtual cluster feature. Then, the control unit 140 re-allocates and allocates the virtual machine to the corresponding nodes 110_1~110_N according to the new configuration policy.

In an embodiment, after the new configuration policy is obtained, the control unit 140 can detect the consistent energy signal. When the enable signal is detected, the control unit 140 reallocates the virtual machine to the corresponding node according to the new configuration policy. On the contrary, when the non-enable signal is detected, the control unit 140 does not reallocate the virtual machine, and continuously collects related data of the virtual machine of the virtual cluster to retrieve a corresponding new configuration policy until the detection It is detected that there is a signal.

The router 150 is coupled to the switch unit 120 for transmitting data of each node to the client 190 via the internet 180, or receiving the data transmitted by the client 190 through the network 180 and The received data is transmitted to each node through the switch unit 120. Moreover, the router 150 of this embodiment may include an outgoing router and an inling router. The output router can transmit the data of each node to the client 190 through the network 180, and the input router can receive the data transmitted by the client 190 through the network 180, and the data received by the input router can be further exchanged through the switch. Unit 120 is transmitted to each node. In this way, the control unit 140 can dynamically move the position of the virtual machine according to the operation of the server system 100, so that the server system 100 is adjusted to an appropriate operating state. In addition, the control unit 140 can also determine whether to adjust the operating state of the server system 100 according to the needs of the user, thereby increasing the convenience of use.

Next, the operation of the server system 100 of the present disclosure will be further explained.

First, after the server system 100 is configured, the user establishes the aforementioned virtual cluster through the graphical user interface, and the virtual cluster has multiple virtual machines. Then, the user generates a configuration command (ie, a configuration scheme of the virtual machine) through the graphical user interface, and is received by the control unit 140. Thereafter, the control unit 140 obtains a corresponding configuration policy in the database 130 according to the configuration command to perform configuration of the predetermined virtual machine to enable the server system 100 to operate normally.

When the configuration policy is prioritized for system efficiency, it means that the virtual machines need to be centrally distributed to some of the nodes. For example, control unit 140 may preferentially configure all virtual machines to the same node (eg, node 110_1). In another embodiment, if the number of virtual machines that can be configured by the node 110_1 has reached an upper limit, the remaining virtual machines are further configured in another node 110_2 in the same area 160_1. Then, if the number of virtual machines that can be configured in all the nodes 110_1~110_3 in the area 160_1 has reached the upper limit, the remaining virtual machines are further configured in one node of another area 160_2 in the same cabinet 170_1 (for example, 110_4, Not shown), and so on, until all virtual machine configurations are complete. That is to say, when the configuration policy is selected as the system efficiency priority, all virtual machines are configured as much as possible on the same node, so that the server system 100 can perform a large number of arithmetic operations.

When the configuration policy is prioritized for a system with a high degree of efficiency, it indicates that the virtual machines need to be configured in the same cabinet, the same area, and the same node. Therefore, the control unit 140, for example, arranges all the virtual machines in the cabinet 170_1, the area 160_1, and the node 110_1 in order. When the system efficiency of the system with the degree of "medium" is selected, the virtual machines need to be configured in the same cabinet, the same area, and different nodes. Therefore, the control unit 140 sequentially arranges all the virtual machines in the cabinet 170_1, the areas 160_1~160_2, and the nodes 110_1~110_6, for example.

When you select the configuration policy to prioritize the system with a low degree, the virtual machines need to be configured in the same cabinet, different areas, and different nodes. Therefore, the control unit 140 sequentially arranges the virtual machines in the cabinet 170_1, the areas 160_1 160 160_M, and the nodes 110_1 110 110_N, for example.

When the configuration policy is the download priority and the upload priority, the virtual machine needs to be configured at a node to which the switch closer to the router 150 is coupled. Therefore, the control unit 140 virtual machine is configured at a node to which the switch closer to the router 150 (for example, the switch 121_1) is coupled. When the control unit 140 configures the virtual machine to the node coupled to the switch 121_1 that is closer to the output router, the server system 100 can use the virtual machine to transmit the data through the network 180 in a large amount, that is, the client 190. A large amount of data can be downloaded to the server system 100 via the network 180.

In addition, when the control unit 140 configures the virtual machine to a node coupled to the switch 121_1 that is closer to the input router, the server system 100 can obtain a large number of service requests or data via the network 180. That is, the client 190 can upload the data to the server system 100 via the network 180. In addition, when the control unit 140 simultaneously configures the virtual machine to a node coupled to the switch 121_1 that is closer to the input router and the output router, the server system 100 can transmit the data through the network 180 in a large amount by using the virtual machine (ie, It is transmitted to the client 190) and at the same time a large amount of service demand or data is obtained via the network 180.

When the selection policy is selected to be the "high" download priority and the upload priority, the control unit 140 configures the virtual machine to be coupled to the switch 121_1 that is closer to the router 150 (output router, input router, and output router and input router). Connected nodes. As such, the server system 100 can transmit or receive data in large quantities.

When the selection policy is selected to be the download priority and the upload priority of the degree "middle", the control unit 140 configures the virtual machine to be switched to the switch 121_1 and the switch closer to the router 150 (output router, input router and output router and input router). Nodes coupled between the devices 121_N. As such, the server system 100 can transmit or receive data in moderation. When the selection policy is selected to be a "low" download priority and upload priority, the control unit 140 configures the virtual machine between the switches 121_N far from the router 150 (output router, input router and output router and input router). The node to which it is coupled. As a result, the server system 100 can transmit or receive data in a small amount.

In addition, when the configuration policy is selected as “high, high, high”, the control unit 140 configures the virtual machines in the same cabinet, the same area and the same node, and the virtual machine is disposed in the switch closer to the router 150. (eg 121_1) the node to which it is coupled. When the configuration policy is selected as "Medium, Medium, and Medium", the control unit 140 configures the virtual machines in the same cabinet, the same area, and different nodes, and the virtual machine is disposed in a switch closer to the router 150 (for example, 121_1). A node coupled to a switch (eg, 121_N).

When the configuration policy is selected as "low, low, low", the control unit 140 configures the virtual machines in the same cabinet, different areas and different nodes, and the virtual machine is configured in a switch far from the router 150 (for example, 121_N). The node that is coupled between.

Next, the control unit 140 collects related data of the virtual machine of the virtual cluster, that is, collects the amount of communication between the virtual machines, the amount of data transmitted by the virtual machine, and the amount of data received by the virtual machine. The amount of communication between the virtual machines is represented as the operational efficiency of the data of the server system 100; the amount of data transmitted by the virtual machine indicates the amount of data transmitted to the client 190 via the network 150 via the router 150; the data received by the virtual machine The amount indicates the amount of data received by the client via the network 150 via the network 180.

Thereafter, the control unit 140 analyzes the amount of communication between the virtual machines, the amount of data transmitted by the virtual machine, and the amount of data received by the virtual machine, that is, respectively, by comparing with a preset value to distinguish between "virtual machines." The amount of traffic, the amount of data transmitted by the virtual machine, and the amount of data received by the virtual machine are "high", "medium", and "low", that is, the virtual clustering characteristics of the virtual cluster.

Then, the control unit 140 corresponding to the new configuration policy in the multiple configuration policies in the database 130 according to the virtual clustering feature. For example, when the virtual clustering feature is "high, high, high", it means that the virtual machine in the virtual cluster needs a large amount of computing data, and the virtual cluster needs a large amount of external data communication, so the control unit 140 correspondingly determines the system efficiency. A new configuration policy with a high priority, upload priority, and download priority. After that, the control unit 140 reallocates the virtual machine to the corresponding nodes 110_1~110_N according to the new configuration strategy of “high, high, high”.

When the virtual clustering feature is "high, low, high", it means that the virtual machine in the virtual cluster needs a large amount of computing data, and the virtual cluster needs a small amount of external data communication to receive a large amount of external data, so the control unit 140 correspondingly outputs the system accordingly. The new configuration strategy of “high, low, and high” for efficiency priority, upload priority, and download priority. After that, the control unit 140 reallocates the virtual machine to the corresponding nodes 110_1~110_N according to the new configuration strategy of “high, low, high”. In this way, the control unit 140 can dynamically move the virtual machine according to the operation of the server system 100 to adjust the server system 100 to an appropriate operating state.

In addition, after obtaining the new configuration policy, the control unit 140 may further detect the consistent energy signal. The enabling signal can be generated, for example, by the user through the graphical user interface to control whether the configuration of the virtual machine in the nodes 110_1 110 110_N is adjusted by a new configuration policy. When the enable signal is detected, the control unit 140 reallocates the virtual machine to the corresponding node according to the new configuration policy. On the contrary, when the non-enable signal is detected, the control unit 140 does not reallocate the virtual machine, and continuously collects related data of the virtual machine of the virtual cluster to retrieve a corresponding new configuration policy until the detection It is detected that there is a signal. In this way, the control unit 140 can also determine whether to adjust the operating state of the server system 100 according to the needs of the user, thereby increasing the convenience of use.
