In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a flowchart of a data center construction method provided in Embodiment 1 of the present invention. This embodiment is applicable to the construction of a data center. The method can be executed by a data center construction apparatus, and the apparatus can use software and/or hardware. It can be realized in a way and can be integrated in electronic devices.

As shown in FIG. 1 , the data center construction method provided in this embodiment may include:

S110. Build a data center blueprint according to predefined roles of node devices and connection relationships of different node devices, wherein the connection relationships are implemented based on a network topology map.

In this embodiment, each node device configured in the computer room is represented by roles. Each node device corresponds to a role. And, according to the classification of roles, each role under the same type can correspond to any node device of the same type as the role, for example, each role belonging to the switch type can correspond to any switch in the switch device, which can Increase the flexibility of configuring node devices in the computer room. Based on the selected network topology map, each role is marked in the network topology map, and the role connection relationship in the network topology map is the connection relationship of different node devices. The connection relationship between the node devices based on the blueprint construction process is determined in advance according to the construction requirements of the data center. Compared with the prior art, the data center blueprint containing role tags based on the network topology map can more intuitively find out the connection relationship between different node devices based on the roles of different node devices and the connection rules between roles.

Further, in this embodiment, the network topology diagram refers to a network topology diagram with hierarchical structure characteristics, including but not limited to: a fat tree (FatTree) topology diagram, a VL2 data center architecture diagram, a Google data center network diagram (such as Google Jupiter) or multi-level switching network architecture diagram (Clos network).

S120. Send a movement instruction to the first operation device according to the label information of each character, wherein the label information is used to record the position of the node device corresponding to the character in the computer room, and the movement instruction is used to instruct the first operation device to associate with the character The corresponding node device moves to the corresponding position.

Before the construction of the data center, the electronic equipment considers factors such as how to make full use of the computer room space and how to save the construction cost of the computer room according to the node equipment that needs to be configured in the computer room. The information is marked, and then each label information is stored according to the corresponding relationship with the role of each node device to form a location information table. Subsequently, the label information is matched in the location information table according to the role of the node device, and the node device can be moved to the corresponding location. The roles defined in this embodiment not only have a corresponding relationship with node devices, but also have a corresponding relationship with label information used to record the location of node devices. Therefore, as long as the specific role is known, the corresponding node device can be known, and then the node device can be known. The location information where the device should be placed can also be known. During the construction of the data center, it is not necessary to simultaneously record and count the actual positions of each node device one by one as in the prior art, so the construction of the data center is simplified.

Optionally, the presentation form of the label information includes an identification code with readable information, such as a two-dimensional code or a barcode, and the readable information may include the node device type and node device location corresponding to the role. For example, through identification code identification, the location information of the node device stored therein can be obtained. Taking the location information including the coordinates of the slot position of the cabinet equipment as an example, the location coordinates are sent to the first operating device, and the first operating device combines the location coordinates and the computer room map to move the corresponding node device to the location. The first operating device may be any automated equipment that can be used to transport node equipment and identify label information on the ground, such as a robot and the like.

Send a network connection instruction to the second operating device according to the data center blueprint and the role of the node device moved to the corresponding location, wherein the network connection instruction is used to instruct the second operating device to establish a connection between the node device moved to the corresponding location. network connection between.

The process of establishing a network connection is a process of connecting each node device using a network cable, such as a communication optical cable. Based on the constructed data center blueprint, the node devices at various locations in the computer room establish network connections, and the construction of the data center is completed.

The technical solution of this embodiment is to first construct a data center blueprint based on the network topology map according to the predefined roles of node devices and the connection relationships of different node devices, and then send a movement instruction to the first operating device according to the label information of each role , move the node device corresponding to the role to the corresponding position, and finally send a network connection instruction to the second operating device according to the data center blueprint and the role of the node device moved to the corresponding position, and establish a connection between the node devices at each location. In addition, the data center blueprint constructed based on the network topology map in this embodiment can more intuitively and clearly show the relationship between the node devices through the defined roles. The connection solves the cumbersome process of building a data center in the prior art, simplifies the building process of the data center, not only improves the construction efficiency, but also reduces the error rate in the construction process.

Embodiment 2

FIG. 2 is a flowchart of a data center construction method provided in Embodiment 2 of the present invention. In this embodiment, the network topology diagram is taken as an example with the characteristics of a hierarchical structure, and further optimization and expansion are carried out on the basis of the above-mentioned embodiment. . As shown in Figure 2, the method may include:

S210: Determine roles with isomorphism by using a preset classification method according to the roles of the predefined node devices and the network topology, and obtain at least one isomorphic role group, wherein the number k of isomorphic role groups is related to the network topology The number of layers in the graph is the same, and k is a natural number greater than 1.

Specifically, according to the transformation relationship between the undirected graph and the adjacency matrix, the network topology graph can be transformed into a corresponding adjacency matrix, that is, a data matrix, and then a preset classification method is used to determine the roles with isomorphism. Optionally, the preset classification method includes, but is not limited to, a graph isomorphism algorithm or a machine learning method based on classification ideas, such as a scalable unsupervised learning method based on a GraphWave model.

If in the adjacency matrix A of the undirected graph G, the data in the i-th row and the j-th row are exactly the same, then the node i and the node j are isomorphic. Specifically, A _ij =1 in the adjacency matrix indicates that there is an edge connected between node i and node j; A _ij =0 indicates that there is no connection between node i and node j. By identifying homogeneous role groups, it is convenient to classify device roles, which makes the construction of data center blueprints more organized.

S220: Divide the network topology map into at least k-1 two-layer partial network topology maps according to the number of isomorphic role groups and the connection relationship between the roles in the isomorphic role groups.

Based on the structural characteristics of the network topology map, if there is no cross-layer connection in the connection relationship between roles, for k isomorphic role groups, k-1 two-layer local network topology maps are obtained after division; In the case of cross-layer connection, for k isomorphic role groups, more than k-1 two-layer local network topology maps can be obtained after division.

S230: Mark the roles of each layer in each two-layer local network topology map with parameters respectively, wherein, in each two-layer local network topology map, the roles that are in the first row and the second row respectively and have a connection relationship are used The same parameter markers.

Marked parameters can be represented by any character, such as numbers or English letter combinations, etc., and each character can be marked with one or more parameters at the same time. A role with a join relationship with the same value present in the tag parameter.

For example, the labeling parameters of roles include digital identifiers; correspondingly, roles in the current layer of the network topology map that are connected to the roles in the adjacent upper layer and the adjacent lower layer use two-dimensional digital identifiers (x , y) to mark.

S240. Construct a data center blueprint according to the marked parameters of the roles and the connection rules between different roles, wherein the connection rules between different roles are determined according to the connection relationship of different node devices.

S250. Send a movement instruction to the first operation device according to the label information of each character, wherein the label information is used to record the position of the node device corresponding to the character in the computer room, and the movement instruction is used to instruct the first operation device to associate with the character The corresponding node device moves to the corresponding position.

S260. Send a network connection instruction to the second operating device according to the data center blueprint and the role of the node device moved to the corresponding location, wherein the network connection instruction is used to instruct the second operating device to establish a connection between the node device moved to the corresponding location. network connection between.

The following takes the fat tree topology diagram as an example to illustrate the process of building a data center blueprint in this embodiment:

As shown in FIG. 3 , it shows a schematic diagram of a data center blueprint based on a fat tree topology diagram. The fat tree topology diagram includes four layers, namely: server layer, edge layer, aggregation layer and core layer, each layer corresponds to a role type. The four layers correspond to the roles of the node devices in the computer room, namely the server (ServerNode), the edge switch (EdgeNode), the aggregation switch (AggregateNode) and the core switch (CoreNode). There are four automorphism sets (automorphism), that is, four isomorphic role groups in the fat tree topology diagram. Node devices on the same layer belong to the same automorphic set, that is, all servers are automorphic, all edge switches are automorphic, all aggregation switches are automorphic, and all core switches are automorphic constructed. Among them, if the number of ports on the switch is m, the number of servers is m ³ /4, and the total number of switches is 5m ² /4. At the same time, there are m pods (pods, representing container groups) in the fat tree topology diagram, each pod consists of m/2 edge switches and m/2 aggregation switches, and each pod is connected to m ² /4 servers . As an example in Figure 3, the value of m is 4, the number of servers is 16, and the number of switches is 20. Among them, 2 edge switches and 2 aggregation switches form a pod. The data center blueprint includes the correspondence between roles and their locations. The builder does not need to record the mapping information from node devices to the location of the computer room again. The data center network can be constructed according to the mapping information from roles to locations and the connection rules between roles. .

Regarding the marking and connection of device roles, the implementation processes are as follows:

For the role of core switches, based on the same connection, core switches can be divided into m/2 groups, each group has m/2 core switches, core switches belonging to different groups are marked with different group numbers, and those belonging to the same group Core switches are marked with the same group number.

For the role of aggregation switches, based on pods, aggregation switches can be divided into m groups. Each group has m/2 aggregation switches, and each aggregation switch is marked with a two-dimensional identifier (group, index). The index number (index) of the aggregation switch in each group is the same as the group number of the core switch to which it is connected. Aggregation switches that belong to the same group are marked with the same group number, and aggregation switches that belong to different groups are marked with different group numbers.

For the role of edge switches, based on pods, edge switches can be divided into m groups, each group has m/2 edge switches, and each edge switch is marked with a group number (group). Edge switches that belong to the same group are marked with the same group number, and the group number is the same as the group number of the aggregation switch to which they are connected.

For the role of servers, based on pods, servers can be divided into m groups, each group has m ² /4 servers, where each edge switch in each pod is connected to m ² /4 servers. Each server is labeled with a group number. Servers that belong to the same group are marked with the same group number, and the group number is the same as the group number of the edge switch to which they are connected.

Among them, for roles that can be marked using one-dimensional parameters, roles belonging to the same type and group use exactly the same marking parameters, indicating that these roles of the same type and marking parameters are substantially equivalent roles.

In addition to servers, the ordering of the switch's role list determines the only properly connected adjacency matrix between switches. The connection rules between roles are as follows:

1) Node devices with the same role are not connected to each other.

2) There are connections between switches in adjacent layers.

3) For the role of the core switch and the role of the aggregation switch, if the group number of the core switch is equal to the index number of the aggregation switch, there is a connection relationship between the switches of the two roles, otherwise there is no connection.

4) For the role of the edge switch and the role of the aggregation switch, if their group numbers are the same, there is a connection relationship between the switches of the two roles, otherwise there is no connection.

5) For the role of the server and the role of the edge switch, if their group numbers are the same, there is a connection relationship between the roles corresponding to the server and the edge switch, otherwise there is no connection.

Specifically, in the data center blueprint constructed based on the network topology with hierarchical structure characteristics, each role layer is the server layer, edge layer, aggregation layer and core layer in sequence, wherein the server layer is at the bottom and the core layer is at the top. ;

The parameter marking process for each role in the data center blueprint includes:

Each role of the server layer is parameterized in sequence according to the role group in the current layer to which it belongs. The role group is determined in the process of designing the blueprint, and the roles belonging to the same role group are equivalent in the data center blueprint;

According to the connection relationship between the roles in the edge layer and the server layer, the role of the edge layer is marked for the first time with the group number of the server class role connected to it in the server layer, and according to the current layer to which the role in the edge layer belongs The middle role group is marked for the second time in turn, and the marking parameters of each role in the edge layer are obtained;

Each role of the core layer is parameterized in sequence according to the role group in the current layer to which it belongs;

According to the connection relationship between the aggregation layer and the roles in the edge layer and the core layer, the role of the aggregation layer is marked for the first time with the group number of the edge switch class role connected to it in the edge layer, and the role of the aggregation layer is marked for the first time. The role is marked for the second time using the group number of the core switch role connected to it in the core layer, and the marking parameters of each role of the aggregation layer are obtained;

Among them, when the roles of each role layer are marked according to the role group in the current layer to which they belong, the roles belonging to the same role group are marked with the same group number. When two markings are involved, the parameter placement order of the two markings is not specified. limited.

On the basis of the above technical solution, optionally, if in the process of constructing the data center blueprint, the connection rules between different roles refer to the connection relationship between different roles in each two-layer local network topology diagram, the method also further include:

According to the labeling parameters of the roles and the connection relationship between different roles in each two-layer local network topology map, the reference map matrix is obtained;

Determine whether the reference graph matrix is the same as the target graph matrix, wherein the target graph matrix refers to the original graph matrix corresponding to the network topology graph;

Determine the correctness of the constructed data center blueprint according to the judgment result.

If, in the process of building a data center blueprint based on the defined roles, the connection relationship between the device roles is established based on the two adjacent layers that have a connection relationship in the topology network structure. In the case of errors in the data center blueprint, after completing the construction of the data center blueprint based on the connection relationships between different roles in multiple two-layer local network topology diagrams, the reference map matrix corresponding to the constructed data center blueprint can be calculated, that is, Data matrix, compare the reference map matrix with the original map matrix designed before building the data center. If the two are the same, it means that the currently constructed data center blueprint is correct and can be used to guide the construction of the data center; if there is a difference between the two, It means that there is an error in the currently constructed data center blueprint, and the currently constructed data center blueprint cannot be used to guide the construction of the data center network corresponding to the original network topology.

The technical solution of this embodiment obtains at least one isomorphic role group by using a preset classification method according to the roles of the pre-defined node devices and the network topology, and then according to the number of isomorphic role groups and the number of isomorphic role groups in the isomorphic role group The connection relationship between roles, the network topology map is divided into multiple two-layer local network topology maps, and parameters are marked for each role, and then the connection rules between different roles are combined to build a data center blueprint to guide the construction The data center solves the cumbersome process of constructing a data center in the prior art, simplifies the construction process of the data center, improves the construction efficiency, and can reduce the error rate in the construction process.
