Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Embodiments of the present invention disclose a method, apparatus, device and computer-readable storage medium for determining node topology information based on a storage network, so as to quickly determine topology information of storage nodes according to interconnection information of FC ports.

Referring to FIG. 1 , a method for determining node topology information based on a storage network provided by an embodiment of the present invention includes:

S101. Obtain interconnection information between each FC port of each node in the storage network;

It should be noted that the interconnection information between FC ports refers to the information about the connectivity between FC ports. For example, if P1 and P2 respectively represent the port numbers of the FC ports, the interconnection information (P1, P2) indicates the ports P1 and P2. port is connected. For nodes in the storage network, each node can have multiple FC ports. The interconnection information can only describe the interconnection between different FC ports, and it is impossible to know whether different ports belong to the same node. Therefore, through the interconnection information The interconnection between the nodes cannot be directly reflected, and the topology information of the nodes cannot be obtained directly according to the interconnection information. With the method for determining node topology information described in the present application, the storage end can analyze the FC port interconnection information identified by the storage to obtain the topology structure information of the FC network where the storage is located. According to the analyzed results, the user can intuitively see the actual interconnection information based on network nodes.

S102. Determine independent sub-networks of the storage network according to the interconnection information; wherein, each independent sub-network is composed of FC ports and switches with interconnection;

In this application, since the interconnection information records the connectivity of different FC ports, based on the connectivity of each FC port, an independent sub-network of the storage network can be obtained, and the number of the independent sub-network may be one, or may be There are more than one, which is mainly determined according to the port connectivity status recorded in the interconnection information. And, due to the reality of network connections, a port can only be directly connected to another port, just like a line has only two vertices. If multiple ports can be reached from one port, there must be a fork between the ports, and there must be a switch at the cross point of the fork. For example, if there is interconnection information (P1, P2) and (P1, P3), it can be seen that P1 can be connected to both P2 and P3, that is, one port of P1 can reach the two ports of P2 and P3, Then, in the independent sub-network composed of P1, P2 and P3, there must be a cross point between P1, P2 and P3, and the cross point is the location where the switch exists. Therefore, in this application, the independent sub-network is composed of FC ports and switches with interconnection.

S103 , using the corresponding relationship between each node and the FC port, aggregate and replace the FC ports belonging to the same node in the independent sub-network to obtain the actual topology information of each node.

It should be noted that, in this solution, the independent sub-networks included in the storage network can be analyzed according to the interconnection information of the FC ports obtained by the storage end, and the FC ports are divided into corresponding sub-independent sub-networks, thereby generating Port and network attribution information. After the network analysis is completed, each port is aggregated and abstracted into a node by using the corresponding relationship between the node and the port in the storage itself, and then the topology information based on the node is generated. Here is a case to illustrate S103: if the independent sub-network includes: P1 is connected to P2 and P3 through a switch, and P1, P2 have a corresponding relationship with node 1, and P3 has a corresponding relationship with node 2, then in this independent sub-network In the sub-network, if P1 and P2 are aggregated and replaced by node 1, and P3 is replaced by node 2, the generated actual topology information of nodes corresponding to the independent sub-network is: the topology relationship between node 1 and node 2.

Further, in the present application, after obtaining the actual topology information of each node, the method further includes: comparing the actual topology information with the planned network topology information, and judging whether the actual topology information and the planned network topology information are the same; if If it is different, a fault link prompt message will be generated.

It should be noted that, after obtaining the actual topology information, the present application can compare and analyze the actual topology information with the preset planned network topology information to determine whether the actual topology information is consistent with the planned topology information. There may be a faulty link in the network, at this time, a faulty link prompt message can be generated to remind the user of possible faults in the storage network, thereby effectively assisting the user to analyze and deal with network connection problems.

To sum up, it can be seen that this scheme uses algorithms to automatically realize the work that originally required manual analysis and manual investigation, which improves the analysis efficiency and avoids human omissions. According to the analysis results, users can quickly grasp the actual network topology information, quickly find problems, locate problems, and solve problems.

Based on the foregoing embodiment, in this embodiment, determining the independent sub-network of the storage network according to the interconnection information in the foregoing S102 specifically includes the following steps:

S11. Select unanalyzed initial interconnection information from interconnection information;

S12, setting the interconnection relationship of the two FC ports of the initial interconnection information in the initial sub-network, and using the FC port with the interconnection relationship as an identified port;

In this embodiment, when establishing an independent sub-network, it needs to be determined according to the interconnection relationship between the ports. If the two ports have interconnection information, it is considered that the two ports have an interconnection relationship. For example: Suppose that the unanalyzed FC port interconnection information forms a set S1; select a piece of initial interconnection information (P1, P2) from the set S1, and the initial interconnection information includes the port numbers of two FC ports that can identify each other, respectively P1, P2.

Here, in order to better illustrate the process of establishing an independent sub-network, it is assumed that P1 and P2 are two points on the horizontal axis of the plane coordinate system, P1 is at the origin of the coordinate system, and P2 is a point far enough away from P1 on the horizontal axis. This coordinate system can be considered as the initial sub-network N1 of an independent sub-network. Moreover, in this scheme, the interconnection information that has been selected from the interconnection information is called the analyzed interconnection information, and the interconnection information that is not selected from the interconnection information is called the unanalyzed interconnection information. The FC ports in the information are called identified ports. For example, the initial interconnection information (P1, P2) selected from the interconnection information is the analyzed interconnection information, and P1 and P2 are identified ports.

S13, select unanalyzed target interconnection information from interconnection information, and one of the FC ports in the target interconnection information is an identified port;

S14, according to the target interconnection information, update the port interconnection relationship of the initial sub-network, and set a switch at the intersection of the port interconnection relationship;

It should be noted that, in the process of establishing an independent sub-network, it is necessary to select unanalyzed interconnection information from the interconnection information to update the initial sub-network. During the selection process, it is necessary to select the interconnection information including the identified ports. In addition, the present application updates the port interconnection relationship of the initial sub-network according to the target interconnection information, and the process of setting switches at the intersection of the port interconnection relationship may specifically include: adding to the existing port interconnection relationship of the initial sub-network. The interconnection relationship between the identified ports and the unidentified ports in the target interconnection information, set switches at the newly added cross points of the port interconnection relationship; determine whether there is a target switch in the existing port interconnection relationship of the initial subnet, and the port corresponding to the target switch is the same as the one. The port not identified in the target interconnection information has an interconnection relationship; if it exists, the newly added switch is merged with the target switch.

It can be understood that since a port needs to be connected to multiple ports through a switch, a switch needs to be set at each cross point of the initial sub-network. Since a switch can realize the connection between one port and multiple ports, it can switches are merged. For example: the existing port interconnection relationship of the initial subnet is: there is switch H1, H1 realizes the connection between P1 and P2 and P3, and the selected target interconnection information is (P1, P4), then in the existing port interconnection relationship Add the interconnection relationship between the identified port P1 and the unidentified port P4, and generate a switch H2 that realizes the interconnection between P1 and P4 at the newly added cross-point of the port interconnection relationship; at this time, you need to check whether there is a target switch, and the target switch exists. The corresponding port and target interconnection information (P1, P4) does not identify the switch with the interconnection relationship of port P4. In the existing port interconnection relationship, switch H1 has P3 port. At this time, it is necessary to judge the switch H1 from the interconnection information. Whether the P3 port has an interconnection relationship with the unidentified port P4 in the target interconnection information (P1, P4), if it exists, H1 and H2 can be combined as a switch.

Here, based on the above process of establishing the N1 network, a specific situation is listed to illustrate the process of S13-S14:

1) Select a piece of target interconnection information including the identified ports in the N1 network from the set S1, the target interconnection information is (*, P1) or (*, P2), * represents the unidentified port, and the target interconnection information is used here. Explain for (P1, P3);

2) Select an intersection between the P1 and the N1 network in the middle of an entity closest to P1 (currently P2), as H1, H1 exists in the network as a switch, and P3 is interconnected with P1 through H1, because the FC network It can be determined that there is a piece of interconnection information (P3, P2) in S1, and P3 and P2 are also interconnected through H1;

It should be noted that since this application will abstract the positions of P1 and P2 into the coordinate system, for the convenience of calculation/understanding, the position of the switch H1 is selected at the middle position on the straight line segment determined by the two points P1 and P2, Of course, the position of H1 can also be selected at any position on the straight line segment of the two points P1 and P2, which is not specifically limited here.

3) Continue to select a piece of target interconnection information containing the identified ports in the N1 network from the set S1, that is (*, P1) or (*, P2) or (*, P3), where the interconnection information is assumed to be (P1, P4 );

4) Select a point in the middle of an entity (currently H1) closest to P1 in the P1 and N1 networks as switch H2, assuming that P4 is interconnected with P1 through H2;

5) Find out whether there is interconnection information (P3, P4) in the set S1. If it exists, it is considered that H2 is the target switch, and H2 can be merged with H1. If it does not exist, we consider that H2 is an entity independent of H1;

It should be noted that if P3 and P4 cannot be connected, it is considered that H2 has been configured, which restricts the connection between P3 and P4, and is considered to be an independent H2 in form. If P3 can communicate with P4, it is considered that H2 is actually H1 in form. Although it may be two independent in fact, it is one in terms of business performance, which cannot be determined only through interconnected information.

S15, determine whether there is target interconnection information with an identified port in the interconnection information; if so, continue to execute S13; if not, execute S16;

S16, take the final initial sub-network as an independent sub-network, delete the analyzed interconnection information from the interconnection information, and delete the identified port;

S17: Determine whether there is unanalyzed interconnection information in the interconnection information; if so, continue to execute S11 to identify other independent sub-networks in the interconnection information; if not, end the process.

It can be understood that after analyzing the target interconnection information, it is necessary to continue to obtain the target interconnection information (Pm, Pn) involving the identified ports in the N1 network from the set S1, where Pn is the identified port in the N1 network, and Pm is the N1 network. Unrecognized ports in the network, and continue to perform S13-S14 for sub-network aggregation, until there is no target interconnection information involving the identified ports in the N1 network in S1, the N1 network topology identification is completed, an independent sub-network is obtained, and all The identified interconnection information is removed from the set S1; if there is still unanalyzed interconnection information in the interconnection information, continue to execute S11 to identify a new sub-network, until the set S1 becomes an empty set, the storage network topology identification is completed, and the generation of Corresponding information of ports and networks.

It should be noted that this application needs to obtain storage node information, which includes the FC port number information of each storage node, and then obtain the host port number binding information that has been configured in the storage system, and the information includes the configured ports. host aggregation information, that is, the information records the correspondence between a node and a port number. After obtaining an independent subnet reflecting the attribution information of ports and subnets through the above steps, the nodes and the network can be correlated with each other by combining the obtained storage node information and host port number aggregation information to generate node-based network topology information.

To sum up, it can be seen that the application can analyze the topology structure of the FC network where the storage is stored at the storage end, and generate node-based network topology information, so as to obtain the network topology information quickly and accurately, and after the logical analysis is completed, it can be graphically analyzed. The network topology information is displayed in the way of , so that users can intuitively see the FC network topology structure where the storage is located and improve user experience.
